Hot Tub Hijinks

Hot Tub Hijinks

By Caligula

Roy was in the hot tub with his sister Grace. They had always been very close...too close. The siblings had always teased each other sexually, and where Grace was naturally dominant, Roy was naturally submissive. It worked out for a perfect relationship between them.

The first time they both realized they were turned on by opposite sides of the same coin, and became sexually attracted to one another, was when they were roughhousing and Grace accidentally kicked Roy in his balls. Roy fell to his knees and Grace went to his aid, giggling at his exaggerated moans. As she pried his hands away from his crotch and felt the area, she realized her brother was hard. They talked about it afterwards and Roy admitted that something about her kicking him had turned him on. It was like she activated a switch in his brain. He also confessed that he found her very attractive. Grace in turn revealed that she had gotten wet when she kicked him, and that she also found him to be really good looking.

And things progressed, as these things often do. Grace took to wearing revealing clothing...crop tops, daisy duke denim shorts, tight leggings that would showcase her camel toe...and Roy was mesmerized by it all. It wasn't uncommon to find them together watching a movie, Roy's fingers rubbing his sister's womanhood thru her tights, with Grace's hand in his lap squeezing his balls. The teasing was constant and Roy often wondered if women could suffer from blue balls the same as guys.

So they sat there across from each other in the hot tub, Roy without his swim trunks on. Grace's foot was between Roy's legs, the ball of her foot and her toes caressing the tip of his rock hard cock. He moaned softly, enjoying this moment so much. Grace traced down the length of his shaft with her foot, and then gripped his balls with her toes and squeezed. Roy moaned again, this time a different type of moan as his sister's toes gripped his nuts and tortured them. She smiled knowingly and released his balls and went back to rubbing the tip of his cock.

And then quite suddenly her foot was gone and Roy's mind started to work again. Their mother Marie was lowering herself into the hot tub and took a seat next to Grace. Normally Roy wouldn't mind seeing their mother in her bikini and spending hot tub time with her, as his mother was very attractive for her age. But their mother's sudden appearance meant the fun was over. He looked at Grace and she gave him a "what are you gonna do?" look and a small shrug.

Staring at his mother's boobs in her tiny bikini top did nothing to shrink the size or intensity of his erection, but it just caused more frustration as now there was nothing he could do about it. Between the four really big boobs sitting across from him. and the tiny revealing bathing suits, he just continued to ache.

And then his sister's foot was back! He felt the friction from the ball of her foot as she returned to teasing his cockhead. He looked up at her quickly and she was just smiling at him. He was thankful that the froth from the bubbles disguised the stroking from the oh so soft foot that was expertly stroking his manhood. Provided they both played it cool, their mother would never know that her daughter was jerking off her son.

And then the toes were squeezing his balls again and he found it harder to maintain his composure. Wow she was really getting rough, he thought.

"So how was your first day at college today Roy?" asked his mother. It's almost like she knew he needed something to distract him from his sister's crushing toes.

"Good," he said, with a higher pitch than he normally spoke with. "It doesn't seem like the classes are going to be too...rough." He said the last word looking at his sister, who gave him another small shrug.

His sister's foot isolated his right nut and started tugging it away from his body, squeezing and twisting his nut like it was a stressball. He whimpered slightly.

"That's good. I'd hate to see you get overwhelmed. Between school and your part-time job it would be very easy to bite off more than you could chew. Life can be a real KICK in the balls, so enjoy it while you're young." said their mother.

Roy blushed at his mother's statement, but Grace laughed. "Oh I agree," she said. "Life really can kick you in the balls. Right Roy?

Damn she was really working that nut over. "I...I guess. I never gave it much thought." he said through clenched teeth.

And then his ball was released and the foot was back to alternating between rubbing his frenulum with the ball of her foot and twisting her toes back and forth on his glans. His eyes rolled slightly up into his skull as he enjoyed his sister's talented toes. It felt like she was switching between trying to buff the wax on a freshly washed car and trying to unscrew the cap off a pickle jar.

"Well you should be thinking about it," said their mom. "You need to protect the family jewels."

And then his sister grabbed his balls again, even rougher than before. It took every ounce of self-control not to cry out. As it was his body spasmed slightly with the viciousness of her kneading toes and he bent forward, while fighting his body's natural reaction to force him into the fetal position.

And then his sister announced, "Well I'm gonna go in and get ready for bed. You two have fun."

Grace stood up and stepped out of the hot tub, and it was only then that he realized it was his mother's foot that was clenching his balls and masturbating his cock. It was his sister who had been unaware of what was going on under the roiling water, and his mother who was playing the little vixen. Grace went inside the house and left mother and son alone.

He just stared open-mouthed at his mother who grinned and returned to stroking his shaft and tip with her loving foot. And suddenly his mother understood and it was her turn to be surprised. "Oh! You thought it was your sister who was jacking you off!" She laughed.

"I...uh...uhhhhhhh..." he lost focus as his mother's foot continued to feverishly work his knob.

"Now that your sister is gone you and I can talk. A mother has needs after all, and I've honestly been day dreaming about hurting your balls for quite a while now. Sometimes life kicks you in the balls, and sometimes it's your mom." she said with a smile.

"Uh...yeah...uuhhhh...kick my balls...yeah...uhhh..." was all Roy could manage to say.

"Now what I have to decide," said his mom, "is whether I help you BUST a nut, or whether I BUST your nuts."

And then she took her bare heel and rammed it into his family jewels. Roy finally gave into the pain and squealed like a girl as he grabbed his mother's foot under the water, and finding he lacked the strength to free his trapped nuts. He finally stopped struggling and just looked at his mother, who seemed to be lost in a dreamy haze of her own. The hot tub shut itself off at that moment, the froth cleared, and he could see his mother's fingers working down in her bikini bottoms. She involuntarily twisted her foot, further crushing his balls, as she approached orgasm.

It was only as Roy pleaded, "Mom...you're crushing my balls," that she finally reached climax and removed her foot from her son's groin.

Through heavy breaths she said, "I want you to tell me everything that's been going on between you and your sister. And if you don't, the next time your sister goes to play with your boy bits, she's going to find that your balls are missing."

Marie smiled at her son and raised her eyebrow. "Well?"

Roy sighed and started to spill the beans, realizing that his life was about to change yet again.
