Jimmy takes her from behind
From Torg Adventure
Jimmy's cum felt warm and comforting in Jenny's womb. She could feel it's heat inside her. Her heart rejoiced that Jimmy was the one to take her virginity and make her a true woman. You can't get pregnant your first time, she thought, so she didn't tell him she was not on birth control. Little did she realize that she had ovulated on the flight to Aruba, and she was at her peak fertility. His sperm was swimming hard and fast in her uterus, and an egg was drifting down her Fallopian tubes, eager to meet them for drinks and dinner.
Jimmy's big brain wasn't thinking of much at all, except how crazy good it felt to fuck Jenny and cum inside her. He figured that she would have said something if she needed him to pull out without filling her with sperm. Still buried balls deep inside her, Jimmy's cock was starting to revive from the twitches of Jenny's inner muscles and the wiggling of her body.
"That was fantastic, Jenny. I didn't know you were still a virgin."
"Mmm-hmm, but I'm glad you were the one. I feel protected with you."
"Well, now that you've done Cowgirl, we should go through as many positions as we can, so you know what they are." He pushed her body up and off his member, and stood up. "I think we should try from behind now."
Jenny kissed him and fondled his junk. It had been semi-hard, but her fingers brought him to full-staff in seconds. Jimmy pushed her shoulders over, and Jenny braced herself on the side of the hot tub. Jimmy rubbed his sister's fine ass, and slapped it sharply once. Jenny squeaked, then turned back to him with a smile.
"Not so hard, big boy! I'm a delicate fucking flower!"
Jenny loved the feel of her brother's strong hands gently grasping her hips. She spread her legs wider, and bent lower to give him a good look at her ass and pussy lips from behind. As he got right up behind her, she reached through her legs and guided his cock to her throbbing womanhood. She couldn't get him inside her fast enough.
She gasped when he thrust into her. It felt just as good as the first time, maybe even better, since Jimmy was a little deeper inside her. As Jimmy started pumping his stiff shaft in and out of her, she cried out in passion every time he was all the way in. A burst of pleasure exploded inside her when he hit that deep. She was going to come very fast this time.
Jimmy grunted as he plunged into his sister. She was so tight, yet so wet and slippery. Her squeals and moans got him really worked up. The water splashed as he plundered her body till his continued thrusting into her G-spot brought her to climax. She shrieked and writhed below him, and her pussy squeezed him rapidly. He roared as he pushed as far inside her as he could reach and his cock erupted in a shower of fertile sperm. Gravity in this position as well as her sustained orgasm helped pull his tiny swimmers deep into her womb, giving them a boost in their arduous journey toward her patient egg.
Jimmy stepped back, pulling his shaft from his sister's shaking body, and sat on the other side of the hot tub. The fast sex and the sun from earlier had taken their toll of his energy. Jenny sat with her ass in the air, overwhelmed by the ecstasy she felt, unconcerned and unaware of the possibilities in store for her and Jimmy.
