Sarah with a twist of her head and a pop, took Derrick's dick out of her mouth, and with half annoyance and lust she stood up and looked the increasingly desperate young man in front of her and stated, "Oh no, I don't swallow. If you want those little wrigglers out of you, we're just gonna have to do this the old fashioned way."
Derrick, who was beginning to think he might suffer from blue balls if Sarah delayed any longer, agreed and began to paw at her clothes to speed the process up. Not only was he due for class soon, but he really needed this done and out of his system.
Before he knew it, Sarah was guiding his erection right into her, causing them both to shudder before Sarah grabbed a hold on a fold-up ladder that was leaning against the wall as Derrick began to move his body into a rhythm that was fast enough for them both, without going too fast at first. The pulls and pushes became faster with each passing second and then, Derrick felt a release as the sperm that made up Tanner was released into Sarah's waiting womb.
Derrick released himself before Sarah came to her own climax. Knowing that Derrick would need a few seconds to recover from the afterglow, she took a deep breath and then pulled her lover's ear down to her lips and whispered in a low but demanding growl, "Now it's my turn, and you better deliver."
Derrick, still somewhat foggy after his release knew that he'd cum earlier than he usually did, and even after releasing that load still felt himself still half-way cocked, so he it was time to make this closet rendevous worth Sarah's time for doing him the favor of getting him off--and besides perhaps round two could work to the benefit of them both. And so he began stroking lightly on the inside of her thigh, working up as he continued to push and pull. His hand then, unable to go further in, slowly traced itself up over her ever so slightly curving belly and to her smaller but still ample breasts.
Sarah moaned softly as Derrick's hands roamed up her body gently and then began to caress her breasts which for some odd reason were beginning to feel somewhat sore and in need of some attention and love. And so Derrick worked at pleasing her, himself beginning once again to feel aroused within her and so he picked up speed.
Unbeknownst to either of them, up in Derrick's dorm room the Chronivac had turned itself on and the following words on the screen lit up:
Error Detected. Correcting the Problem.
Within Sarah's womb at the same time, the sperm that was Tanner suddenly hurried up, travel at double the speed to find an egg ready and waiting to be penetrated, which he did.
