Part 4

My Sister in Law Cindy tries Ballbusting Here are some stories about my sister in law Pam, this is complete fiction, except for the descriptions of the women.

I'm on vacation this week with my wife Marcy and her two sisters, Pam and Cindy. Pam and I have always had kind of flirty relationship, and this vacation I accidentally touched her breasts and pulled her swim suit top off. She's been blackmailing me ever since, threatening to tell Marcy that I did it on purpose if I don't do as she says. Most of what she says is that she wants to bust my balls, in exchange she lets me play with her absolutely perfect breasts, and she let me cum a few times, but mostly I am just getting my balls beaten on.

The strange thing is, I like it. I've been completely on edge all week, and Pam keeps flirting with me and grabbing my balls at every opportunity, my cock has been hard at least half the week. And Marcy caught me with a hard on and figured it was because I was looking at her tits, and she give me a sympathy blowjob. Things are working out my way.

Marcy and Pam wanted to go down to the pool early to swim some laps, I decided to just hang out in the apartment and read the paper. I didn't know where Cindy was, but I found out soon. Cindy came walking into the living room wearing just a bottom of a swimsuit, and that swimsuit bottom was really more of a thong than a bottom.

"Hi Matt, I hope you don't mind, but since no one else is around I hate wearing swimsuit tops and bras. I have great tits, why restrain and hide them?" she said.

I looked up at her, "Wow, you're right, your tits are perfect. The women in this family all sure have nice racks." I said.

Cindy laughed at me and walked around the living room cleaning up, I tried to read my paper, but my eyes followed her wherever she went.

"Matt, come into the kitchen and help me put away some of this stuff in the high cabinets." she said.

I followed her in, staring at her ass with every step she took. She handed me some boxes and I put them over the oven. Then I helped her clean up. She started doing dishes and I couldn't help but stare at her ass as she worked.

"I see you staring, it's okay, you can touch my ass. And if you want you can touch my tits too." she said.

Wow, this got real quick. I started to walk towards her.

"It might cost you though." she said.

"Let me guess Cindy, will I be paying with my balls?" I asked.

"Yes Matt, I hope so. Pam told me she's been busting your balls this week, and I have always wanted to try ball busting. I'm the only one in the family who has never done it before." she answered.

"Pam said you would let me do just about anything to your balls if I gave you a blowjob."

"Pam told you that? She's probably right, but I'm surprised she talked to you about it." I stammered.

"We're sisters Matt, we share everything, that's how it is around here." she answered.

That was something to think about, I wondered if she was saying that Marcy knows what's going on here too. It has been very convenient how I keep being left alone with Pam, and now suddenly when Cindy wants to bust balls I am alone with her. Something to think about later, but for now, Cindy's tits had me more interested in them. I walked straight up to Cindy and put my hands on her breasts, she didn't flinch. I pulled over a kitchen chair and sat down, I pulled her down onto my lap and sucked and kissed her breasts.

Cindy has these cute freckles on her chest, especially between her breasts, for some reason I just find that very attractive, I was completely taken with Cindy's tits. I could have spent the day playing with them. My cock was getting hard and straining to get out of my swimsuit, I'm sure Cindy could feel it push up on her as she sat in my lap.

"Matt, let's get your swimsuit off, and let's get started. I would like to squeeze your balls first, just to get a feel for it. Are you ready?" Cindy asked.

I gave her one last squeeze and we stood up, I took off my suit and stood in front of Cindy naked. My cock was hard now, it pointed at Cindy.

"Pam also told me you have a big cock, and she was fucking right. You are even bigger than my ex, when we get to the blowjob later, this will be a challenge." she said.

Cindy reached down for my balls, she cradled them in her hand. "I am going to squeeze your balls, I want to get a feel for what you can take." she said.

She started pretty easy, still I winced a bit.

"That hurt you?" she asked.

"Yes, but not terribly, I can take more." I answered.

She squeezed harder and harder, soon I reached for her shoulder to steady myself, and not much later my knees started to give out from under me. I was heading for the floor when she finally stopped.

"Holy shit Matt, balls are that sensitive? I never would have guessed." she said.

"Yes Cindy, they really are, go ahead and give me a quick really hard squeeze, maybe dig your thumb into one and you will see." I answered.

I wasn't sure why I would answer that way, but I wanted Cindy to give me the full hurt for some reason, it felt good to have another woman do it to me too. I must be going crazy.

Cindy felt around my balls for a moment, adjusting her grip, and then she dug her thumbnail into one of my balls. The pain was intense and quick, I dropped to the floor immediately.

"Fuck, my balls." I cried out.

Cindy started laughing at me as I lay on the floor, "Pam told me if I really nailed you that I would hear you cry out my balls my balls. She said all men do it." Cindy said while still laughing at me curled up on the floor and clutching my balls in my hand.

"Come on Matt, get up, I want to do it again, it's making me horny as fuck." she said.

I slowly worked my way back to my feet, it helped me get up watching Cindy's magnificant breasts as she bent over to give me a hand. She held my cock in her hand and slowly jerked me off.

"I'm sorry I hurt your balls so much, I will try and take it easier, I just can't believe how weak your balls are." she said. As she spoke she continued to stroke my cock back and forth, I was starting to feel better and better. Of course I was staring at her tits.

"Pam told me if I really hurt you I should blow you for awhile so you feel better, do you want me to do that?" she asked.

Of course I said yes, she knelt down and took my cock into her mouth. She was just as good at blowing me as Marcy and Pam were, she had been married, she knew how to handle a cock. Her tongue flicked around the head of my cock, and she licked the shaft. She worked me softly for awhile, eventually I started pushing into her mouth. soon I gagged her.

"Fuck Matt, your cock is too big, I thought my ex Tony's was big, but this is ridiculous. Are you feeling better yet?" she asked

"Yes, I'm pretty much recovered. Thanks Cindy, you do that very well." I answered.

"Yeah, I've had some practice." she said. She stood up next to me. "Matt, I would like to kick you in the balls, Pam told me that is the ultimate, total power over a man. I was so excited just from squeezing your balls, I want to see how kicking feels."

"Okay Cindy, but do the first few easy, you have to learn to control it or you will just crush my balls and then I will be useless until I can recover." I said.

Cindy stepped back and lined up a kick, I looked down to see if my cock was in the way, but of course I was hard from the blowjob.

Thump! Her foot swung up to meet my balls, pain flooded my balls and then my stomach, she had nailed my left ball. I could feel it smash up against my pelvis and compress. I started to fall to the ground, but managed to stay up at the last second. I was bent over with my hands on my knees panting, trying to catch my breath.

"Shit Matt, I was really holding back, it's that bad?" she asked.

"Yes Cindy, it's that bad. You really smashed my left ball, I could feel it squash against my body." I answered.

She knelt down in front of me and took my balls in her hand.

"Oh yes, this one is red and maybe a little swollen. Wow!" she said.

"Let me try a softer kick Matt, I just want to get dialed in on this." she said.

She got up and stepped back, she snapped her foot up into my balls. Thump. I didn't know what to expect, she said it would be softer, but my balls were so sore. The pain again flooded through my body, my mind was getting hazy, I dropped to my hands and knees this time.

"Matt, are you okay, I thought I didn't kick you that hard." she said.

"You didn't, but I didn't recover long enough, my balls are so sore that they are crazy sensitive now." I said. I stayed on my knees for another few seconds just trying to breathe, then I tried to get back onto my feet. As I turned I saw that Cindy was fingering herself. She was definitely getting off on crushing my balls. That made me want her more and more. Her eyes were closed, I just stared at her tits as she fingered herself. I didn't want her to stop, but she noticed that I was trying to stand.

"Matt, can I kick you once more, I'm so hot that I think it might make me cum." she said.

She looked so fucking beautiful and sexy, her tits were so great, what could I do. "Of course Cindy, I want you to kick my balls." I said.

She smiled at me, she lined up with me, and she took another hard kick at my balls. THUMP!

The next thing I remember I was on the floor on my back, I opened my eyes to see Cindy sucking my cock while she held my balls in her hand. I was dizzy and a little nauseous, but I was starting to feel better as she worked my cock.

"Matt, are you awake, are you okay?" she asked.

"Yes Cindy, I think so, you really nailed me." I said.

"I didn't mean to kick you so hard, I'm not sure what happened. I'm sorry Matt, can I make it up to you?" she said.

I didn't know what she meant but I nodded yes. She did what I was hoping she would do, she climbed onto me and put my cock into her pussy. Fuck yeah.

She was completely worked up, we managed about two strokes before she started cumming. And she was having a good one, she was screaming out, "Fuck me Matt. Holy fuck!". She started riding me faster and faster, her breasts were swinging back and forth, her face was red, her hair was everywhere, she looked so fucking hot. I started cumming too, there was no way I could slow myself down.

"Ohhhh fuck!" I moaned. I shot loads of cum into Cindy, she was just hammering my balls with her ass, it hurt but I was loving it, the pain and pleasure mixed together. She kept riding me even after I was spent, she was still cumming and I didn't want to stop her, but it was start to get really intense for me. Just as I was about to push her off of me, she let out a loud groan and wrapped her arms and legs tightly around me and just held on.

"Fuck Cindy, that was incredible. What are we doing?" I asked.

"Well Matt, that was fucking. It was next level fucking for sure, but that was fucking." she said.

"Yeah, I know that, but you are Marcy's sister. It's pretty obvious that she knows what's going on, why are you sisters doing this to me?"

"You're right Matt, she knows, but I don't want to answer you. Marcy will do that when she's ready. For now you can just enjoy it."

I just lay there on the floor with her on top of me recovering from both the beating and the orgasm, I heard the Marcy and Pam come in from the pool. There was no use getting up and running away, whatever was going on was about to come to an end. This should be interesting…

Part 5

My Wife's Plan to Bust My Balls Finally Revealed Here are some stories about my sister in law Pam, this is complete fiction, except for the descriptions of the women.

I'm getting near the end of my vacation week with my wife Marcy and her two sisters Pam and Cindy. It has been a crazy week, first Pam and then Cindy have been blackmailing me with threats of telling Marcy that I grabbed their tits. In exchange for not telling on me, they have been busting my balls. Hard. My nuts are killing me.

I've been kneed, kicked, and squeezed to within an inch of my life. It's not something I've ever done before, but I have to admit that I like it. They have kept me completely on edge all week, my cock has been hard almost the whole week, it's been a lot of fun, but in the back of my mind I have been wondering what Marcy will think of this.

In the last couple days I have come to realize that she knows what is going on. I asked Cindy to tell me, but she refused, she said Marcy would tell me when she's ready. She had to be ready soon, because she had just walked in on Cindy and me as we finished fucking in the middle of the living room.

I decided to head her off at the pass, to let her know that I knew. "Hi Marcy, your plan seems to be working, whatever the fuck it is. Your sisters have been having a real party with my balls." I said. Cindy climbed off of me, she pulled her thong back on and sat on a towel on the couch.

"I didn't tell him anything Marcy, I Ieft it to you, but he figured out that you knew." Cindy said.

"Yeah, I expected him to eventually figure that out, it's okay." she said.

Marcy sat down next to me as I lay on the floor, "I probably should have told you earlier, but I knew you were having fun with Pam and her huge tits, and I knew you would enjoy Cindy too, and she was so excited to play with your balls."

"So here is the truth Matt. Our marriage is very valuable to me, and I wanted to take us in this direction for a while, but I wanted to be sure it could work for you. Pam loves busting balls, and she volunteered to find out how you would react. I'm not the jealous type, so I let Pam have some fun with you. At this point I believe it's pretty obvious that it could work in our marriage. If it hadn't worked, if you had freaked out, then I would have dropped it and our marriage would have continued as before."

"Matt, you've had nearly a week of how things could be, I would like to continue this way. I have no problem with our sex life, but you can see that it can be much more intense. I love busting balls, but I would only do it to you with your permission. And just to add to the fun, my sisters would like to continue with you too if that's okay with you. It's up to you." Marcy said.

I could barely believe what I was hearing, and even though I had just cum a few minutes before, as Marcy spoke my cock was getting harder. I know that she already knew my answer, but I said it anyhow.

"Absolutely Marcy, will of you all kick my balls please?" I asked as I looked around the room. "Though I could use a little while to recover first, I just came, I'm pretty sensitive."

Marcy took my balls in her hand, she examined them closely, "Yeah, you're not kidding, this one is a bit swollen, Cindy must have nailed you today. Let's wait until after lunch." she said.

Marcy squeezed my balls, for the first time, she's so fucking sexy, I loved having her hand on my balls. This was going to be fun.

"Let's hit the pool for awhile, I could use some chill time." Marcy said. We all went to our rooms and got dressed, I took a quick shower and got dressed, I was the last one to get to the pool. The three sisters were lying around in tiny swimsuits, I felt a bit like I had a harem, but I knew that was bullshit, they had me.

We laid about the pool for a couple hours, Marcy was the first to head up for lunch, I went with her.

"I'm excited to play with your balls Matt, I think we're going to have a lot of fun." Marcy said to me as we entered the apartment. "Pam tells me you are pretty tough, I thought you would be. And both my sisters keep going on about how big your cock and balls are, you are very popular in this family." she said.

A few hours ago I was worried that Marcy might divorce my cheating ass, now I found out she arranged all of it.

"Marcy, this is new ground for me, I don't know what to say to something like that, but I love you and I am excited to move into this next phase of our marriage." I said.

"You couldn't have said anything better than that Matt, you are a sweetie." she said. "Let's eat first, then I want to have some fun."

Marcy went to our room, she took off her suit and switched to a loose fitting tank top and some very short shorts. She looked incredible, I watched her every move as we made lunch and ate. I must have peeked a look down her top fifty times in that half hour, her breasts looked so squeezable, I couldn't wait to get at them. I ate most of my lunch with an erection under the table.

After we finished we went back to our room, she pulled her top off and smiled at me, "I hear you will let girls squeeze your balls if we let you play with our breasts."

"Yeah, I'm pretty crazy these days." I grabbed her and hugged her, then I felt her up for awhile, I pulled us onto the bed and we made out for a couple minutes.

"Matt, I want to squeeze your balls." she said.

I stood up and took my suit off, I stood in front of her as she sat on the bed. "I want you squeeze my balls Marcy, I can't wait for it."

She cupped my balls with her hand, and the she gave me a mild squeeze, it felt good, I was loving the new Marcy.

"You can squeeze harder Marcy." I said. She tightened her grip, but it still wasn't bad at all, I took it with no trouble.

"I'm more of a kicker than a squeezer Matt, I like to kick balls." she said. She loosened her grip and stood up. "Are you up it?" she asked.

"Yes Marcy, I want you to kick my balls." I said. And I did. I was so hard, I felt like cumming already. It was so exciting to watch her look at my balls and line up her kick. She swung her leg back, then let it fly into my balls. Thump.

It hurt, but she really didn't kick me very hard, I stayed on my feet.

"I can take more Marcy, go ahead and kick my balls harder." I said. Stupidly.

Thump! Again it hurt, but not that bad. She really wasn't kicking me hard.

"Matt, it's really hard for me to kick you. I've done this before, but never to someone I love so much. It's actually difficult for me." Marcy said.

"I understand that, I love you so much too, I want you to nail my balls. I need it from you, I want to give that to you." I said. I meant it too, I really did want Marcy to blast my balls.

THUMP! She let fly a much harder kick, but it was still something I could handle pretty easily, I bent over and had to work to get air into my lungs, but I was recovered in a few seconds. She looked so hot and sexy standing there, I knew she was enjoying kicking me, I decided to just enjoy the lighter kicks.

"Marcy, I am so hot for you, would you please kick me in the balls again." I said.

She smiled at me, and she stroked my cock a few times, then she unleased a real kick finally.

THUMP!

I fell backwards from the force of the kick and landed on the floor on my back, my cock was trying to cum. I couldn't believe it, but it was dribbling pre-cum and throbbing up and down, but the cum wouldn't come out without a little help. Marcy must have noticed too because she lowered her pussy onto my face and at the same time took my cock into her mouth. I sucked on her clit hard, she was completely wet, she was definitely ready to cum or already cumming.

"FUCK! I'm cumming!" one of us yelled. Or both of us yelled, I don't even know. I kept sucking on her clit as I shot load after load of cum into her mouth. We were locked together in a 69 for minutes, it was the most intense orgasm I've ever had, and this week I've had a few unbelievable ones. Cumming like that with my wife was perfect, it was exactly what I wanted. Even if my balls were aching. What a treat.

As we both lay there recovering I couldn't help but think about how great this change to our marriage would be. I had really enjoyed being so charged up all week, and it's clear the women all liked it too. It's a complete change in how we live our lives, it sounds like it will be awesome. As long as my balls can take it.

Part 6

Pam was taking forever to kick me in the balls, she wanted to make the perfect kick. Or maybe she just wanted to torture me, only Pam knows. I stood at attention, my hands behind my back, she stood in front of me thinking while she stroked my cock and occasionally squeezed my balls in her hand.

Pam was naked except for a pair of high heels, her enormous breasts had my complete attention, though I was pretty aware of those high heels too. Pam knew I loved her breasts, everybody there knew, Pam used them to mess with me all the time. It always worked, I can't help myself. More than once I traded a feel for a kick to the balls.

Pam cradled my balls in her hand and gave them a light squeeze, "Maybe I want you on your knees for this kick." she said. She squeezed my balls a little harder when the word kick left her lips.

I stood wondering why I let myself get into these situations. We were having game night with my wife Marcy and her sisters Pam and Cindy, it was the last night of our vacation. Since I lost badly, each of the women got to kick me in the balls at the end of the game. The girls all put on their high heels for the kicking, each was naked with a pair of black heels, they all looked fucking stunning.

Marcy's oldest sister Cindy was the first to kick my balls, but she was easy on me. During the game, I lost a round to her and my task was to eat her pussy and make her cum, she was still a bit in a daze from cumming. I'm sure she wanted to kick me harder, but she just didn't have the strength to really bust me.

She strolled back and forth in her high heels, I watched her strong lean legs as she walked, waiting for my balls to get blasted up into my stomach.

"It's time Matt." Cindy said, and she turned quickly and drove her foot up into my balls. I waited for the rush of pain to flood over me, but she really didn't connect. I was so relieved to be standing afterwards instead of rolling on the floor in agony. Let's be honest here, the kick was still pretty hard, it was just that I was able to stand through it.

"That wasn't your best kick Cindy." Marcy said. "I'll make up for it."

It was Marcy's turn to taunt me, to stroll back and forth in front of me in her high heels, I couldn't decide whether to watch her legs or her beautiful breasts, my eyes were all over the place. She looked so pretty, it was hard to believe that she could be so brutal to my balls. I didn't blame her though, I have been kind of flirty with her sister Pam. Marcy is not the jealous type in the least, but every woman has her limits. Marcy might have found hers.

THUMP!

Her foot snapped up into my balls at full force, the next thing I remember is being on the ground on my hands and knees, just barely able to breathe. The pain from my balls was intense, I had trouble even staying up on my knees. But I didn't want to curl up in a ball on the floor in front of the three women, it would be too embarrassing, so I did my best to just stay up on my knees. I'm not sure it was any more dignified than laying on the ground, especially since I was wobbling a little.

After a couple minutes I recovered enough to get back up on my, and here I am now, waiting for Pam to finish the game. Waiting for Pam to decide how she wants to crush my balls. My already aching balls. Great.

Pam continued to walk around in front of me, trying to decide on the best course of action to destroy my balls. She stopped to look me in the eye, "I don't know what to think, I can kick you harder when you're standing, but I love having you on your knees."

I knew better than to answer, I stood quietly staring at her big breasts. Fuck, I love those tits, even as I was about to get blasted in the balls, all I could think about was burying my head between them, or tit fucking her and then blasting cum into her pretty face. I have a real weakness for big tits, I need to get over that I thought.

"Get down on your knees Matt." she ordered. I did as asked, I dropped to my knees, my face was just about the height of her pussy, her long legs with high heels looked so good from down there.

Pam took her foot and rubbed it against my balls, her leg was rubbing against my cock. It felt great. I wanted to pull her leg into me, but the women told me to keep my hands behind my back when I lost the game. She kept doing it, a little harder each time, I was starting to get pretty excited. The suspense of waiting to get kicked in the balls along with the stimulation always gets to me. Plus, Pam's legs look so good. And then, to top it off, my wife is watching me intently, and she looks fucking awesome standing naked in high heels staring at her sister fuck with my balls.

Pam gives me a light kick, I hoped that might be it, but of course not.

"No, Matt, I decided, I want you standing today." she said.

Pam helped me stand back up, then she took my cock in her hand. "I want to make you cum, and then I'm going to kick your balls while you cum." she said.

That didn't sound that great, just as I give in to the pleasure of cumming, my balls are going to get crushed. Fuck. That's mean.

Marcy looked at me half smiling, she walked over and kissed me. "You poor boy, you must have done something to piss Pam off." she whispered in my ear.

Pam looked me in the eye, "Go ahead Matt, ask me to kick you in the balls." she said.

"Pam, please kick me in the balls." I said. I reached for one of her breasts and squeezed it. It was part of a game we played, we've been doing it since she started busting me.

Pam lowered herself onto her knees and took my cock into her mouth. I loved the feeling as my cock was sucked in, Pam gives great head, she sucks it hard, and it's so much fun to watch Pam's big breasts sway as she blows me. She sucked me for a few minutes, I was getting close to cumming, but not quite there yet.

Pam stood up, she brought her knee up between my legs. She rubbed my cock with her knee, she pushed her knee into my cock and balls, my cock was so hard, it just felt incredible.

Then she pushed her knee up hard into my cock and that was it, "Fuck Pam, I'm cumming." I said.

Pam stepped back, and as the first load of cum came out, she blasted my balls with her foot.

THUMP!

Her foot smashed my balls up into my stomach, flattening them right as another load of cum tried to escape. Cum shot everywhere, onto her foot, up in the air, some on my chest and some on hers. I nearly began to laugh, but then the pain rolled over me and I dropped slowly to my knees. As I dropped down Pam stepped forward and pushed her leg into my cock and balls, I grabbed her leg and pulled it into myself. I was pretty much fucking her leg at this point, I didn't care, I was in the middle of an insanely intense orgasm.

"Pam, kick me again." I heard myself say, almost as if somebody else said it. I let go over her leg and she slammed her foot into my cock and balls at the same time.

THUMP!

Once again a load of cum shot out of me onto her leg, the feeling was insane, both pain and absolute pleasure, the orgam was so strong I felt like fainting. I grabbed her leg again and pulled it into my cock and balls. Holy fuck.

"Another kick Matt?" Pam asked. I nodded yes, she pulled her leg back and drove it into my balls.

THUMP!

"FUCK!" I cried out, the last drops of cum shot from my cock onto her leg, I pulled her leg into me again, then I pulled Pam down on top of me as I lay back. She gently pushed her knee into my balls as I groaned in ecstasy. I hugged her tight, I looked over at Marcy who was watching us, her eyes wide.

"Fuck Matt, that was crazy." Marcy said.

Pam was still kneeing my balls lightly, and I was holding onto her a bear hug, but just then everything in my body seemed to go limp, my arms dropped away, all my energy was gone. I lay on my back completely shot.

As I lay there recovering I thought about how much fun this week had been. My balls hurt, but the whole week was so exciting sexually, I had a hard on almost the entire week. And the orgasms after busting were so good, so intense.

"It's going to be hard to beat this vacation Marcy, I can hardly wait for next year." I said.

"Oh, you wont have to wait until next year, Pam asked if she could come over next week, she volunteered to let us use her however we want. Do we have any rope Matt?" Marcy said.

Holy fuck, things sure changed quick.
