Science Fiction Sex Story: Chapter 7 - When Bob brought some prototype marketing samples of his company's new miracle menopause drug home, he had no idea his niece would find them and think they were just candy. He also had no idea how they would affect her. Oh ... and his nephew got into them too. That's when things just got crazy.

It turned out that while both Clarissa and Matt were fully cognizant of the concept of oral sex, neither had been willing to try that. It was too easy to just just rut, and that got the job done, more or less. The only reason they knew about any position other than the missionary position was because of the accident in which Clarissa lost her virginity.
Clarissa's world expanded a lot that night.
She got over the "ewww" feeling within seconds after he sucked her clitty into his mouth. He chewed it and she went off like a bomb. She was almost crying from the joy of it when he lifted his mouth. He'd only been sucking for a couple of minutes.
"I didn't KNOW!" she panted. "Can you do that again?"
"Dozens of times," he said, smiling.
He got her off four times with his mouth. Then he moved to her breasts and showed her what it felt like to be tasted there. His fingers, much more educated than Matt's brought her three more orgasms while she wailed and squirmed, holding his head to one breast while he sucked lustily at a nipple, and then pushing it to the other breast while her hips arched up to try to get his finger deeper in her.
It was actually her unbridled love of everything he did to her that broke Bob's will to resist completely. His balls started to ache and he asked her if she'd be willing to learn how to please him with her mouth. After everything that had happened her reticence was gone, and she happily agreed.
She was a quick, and avid learner. She loved the feel of the different kinds of skin on his prick against her lips. Several times she took her mouth off of him to closely examine with her eyes what she'd been feeling with her tongue and cheeks. It had the effect of both prolonging Bob's delightful experience and making him tend to get used to her stop and go technique. That was to become important a few minutes later.
She loved that he was so hard for her. She also knew that, no matter how wonderful everything had been, this handsome hard cock in her hand would feel even better in her pussy.
So she stopped sucking it, and sat on it, cowgirl style. Bob just thought she was shifting to a more comfortable position and left his eyes closed. He had no idea she was going to fuck him.
"Ohhhh," she sighed as Bob realized what had just happened. "You're bigger than Matt."
"Oh damn," he groaned as tight, hot pussy flesh surrounded his cock and squeezed it.
"It feels different," she said, giving an experimental twitch with her hips. Her pussy muscles milked the thing in her lovingly. "Not better, exactly ... just different."
The reluctance to do this with his niece disappeared like a puff of smoke in a strong wind. In Bob's defense, that was because his pride was stung. What did she mean it wasn't better?! That sting fueled his lust, and his desire to convince her he WAS better than a stripling youth. He pulled her down and rolled as she squealed, landing on top of her and crushing her to the bed. His knees moved between her thighs roughly and she spread her legs. He'd come halfway out of her during the roll and he surged forward hard enough to make her body move a few inches on the bedspread.
Her "Uhhh!" as he drove deep spurred him on and he stayed deep. Digging in his toes he pushed with his arms until he was lifted enough that her breasts felt spongy and supportive against his chest. Then he moved to his right, squashing her young clit flat.
"AHHHHH," she groaned.
He kissed her while her mouth was still open and licked at her tongue. Her hands, on his sides, tensed as he kept moving, sliding down a little and then completing a circle with the base of his prick, to crush her clit again. He kept moving in that small circular pattern, basically moving only two inches of prick in her as her legs kicked and her fingernails dug into his sides painfully. Then her knees came up and she groaned into his mouth as her heels hit the bed and her loins thrust hard, as if she were trying to lift him.
Continuing his circular assault on her clit, he licked her lips and bit her lower lip gently, pulling at it with his teeth before letting it loose again.
"Oh pleeease," she moaned. "Don't stop!"
"Oh, I'm nowhere near stopping," he panted.
"Gonna cum!" she grunted.
Her mouth opened in a wide, soundless scream as she went rigid. He felt her pussy muscles try to grip him, but he wouldn't let them, pulling out and slamming back in. She made a noise then, a mixture of what sounded like agony and ecstatic joy that started on a low groaning note and ripped up the scale until she was wailing.
He ground harder against her, feeling the tip of his prick battering her young cervix, giving her no chance to rest from the constant stimulation of her sexual center.
"Oh yes," she panted. "It's happening again!"
Over the next ten minutes she went rigid, went completely limp, flopped like a rag doll and kicked as if she were having a seizure, as orgasms came one after another until, finally, her "Oh yes" became "Oh no" and then "Oh nooooo" and finally a gasping "I can't take any more!"
Only then did Bob begin allow himself long strokes in her, providing the stimulation needed to tip him over the edge. She was on the pill, so he could enjoy it fully. His prick belched ropes of thick cum, soaking her pussy and seeping through her cervix into her womb.
"Please tell me you took your pill," he gasped as his prick jerked in her.
She couldn't answer. She had nothing left. She'd used up every bit of energy in her body having orgasms. All she could do was smile a dreamy smile while she caught her breath.
"I didn't know it could be like that," she whispered. Her head was lying on his shoulder and her arm lay limply across his chest. "It's never been anything close to that with Matt."
"He has much to learn," said Bob, feeling much better about his prowess.
"He sure does," she sighed. "I feel like I got caught in the dryer and have been spinning around for an hour."
"We only went twenty minutes," he said. "I'm out of shape."
"Out of shape? Twenty minutes? No way!"
"I used to go for at least half an hour when I was younger."
"How could she stand it?" sighed Clarissa. "I thought you were going to fuck me to death!" She played with the hair on his chest. "Not that I'm complaining, because I'm not. I loved it."
"Me too," he said. "That's the problem. I loved it so much I'm going to want to do it again."
"OK," she said instantly.
"I wasn't supposed to fuck you, sweetheart," he said. "I kind of lost control."
"Technically I fucked you first," she said. "Even if it was only for about ten seconds."
"The point is that we can't do this. I could get in big trouble if anybody found out, and they'd take you away from me."
"Well then we'll just make sure that nobody finds out," she said, with the overconfidence of youth.
"Maybe you should stop taking 684," he mused. "It's pretty clear in my mind that it's what caused your sudden maturation. And life might be easier for you if you didn't get so overpoweringly horny."
"But I like being horny," she complained. "And I love being full of nice hard cock. I love that part the most!"
"You can have that with a man you can love and stay with forever," he said.
"Right now I wouldn't mind staying with you forever," she said. "I already love you and I already know you know how to make me crazy."
"You can't marry me," he said. "You need a man you can marry and have babies with."
"Maybe," she said. "But that will be years from now, so until he comes along, I just want you to do that to me again, every so often."
"How often?" he asked.
"Twice a day?"
He choked and she laughed, delighted that she'd been able to tease him so thoroughly.
Half an hour later she wasn't laughing any more. She was in what he called the three point stance, supporting herself on the bed on her knees and head. That left her ass high in the air, with his thick cock in her pussy from behind.
"You rub your own clit," he said as he reached under her to cup and play with her breasts. "That way you control when you cum."
"It feels so different," she said, her voice half muffled by the bedspread. "It's like I'm getting a massage inside me. I could do this all night long!"
"Well I'm not going all night. I'm going long enough to give you a chance to work off your horny attack. Then I'm going to take a nap."
"Nap?" She was starting to pant as her hand flitted rapidly between her legs. "It's nighttime!"
"I know that," he said. "But I have a feeling you're going to wake up in the middle of the night horny again. If I just take a nap, I won't mind. If I go to sleep for the night I might get grumpy when you wake me up."
