You look at the pill for a few moments, and pick it up. You hold it near your mouth for a bit, pause, and swallow. "Ok." Sarah says. "The couple had sex right after." And in one swoop, she removed her bra and shirt over her head. Topless, her nipples perked upwards, and she began to undo her pants.
"Holy crap!? Are you serious?" You weren't a very stereotypical guy. I mean, you had your weaknesses, but you could usually resist temptation pretty easily.
"Yeah! Now come on! Pants off!" She said.
You began to realize now that Sarah's obsession was more severe than you thought...but you thought about two things. First, you'd get some action, regardless of if this worked or not. Second, You both might grow...
By the time you thought of this, you looked up, and Sarah was nude. The light coming in from behind her made her look like a angel, and her beauty radiated throughout the room. You took off your shirt and pants, and Sarah tackled you, kissing you on the mouth for a while, and then moving down to your neck.
Your penis hardened against her nude body, still in your boxers. She began to grab the waistband, pulled down on it slightly. She huffed in frustration, and ripped your band completely, and then tore down your underwear. She sat up and moved back, and looked at your hard penis, and smiled. "Now think about it..." She started, and began stroking the head of your penis. "This guy...he is a big guy already, dont you agree?" She said, not realizing you weren't even fully erect yet.
You nod, and your penis continued to harden and grow.
"Actually, you are very big..." She said, stroking your member, it swelling slowly in your hand, until it reached it's full erect status of 12 inches. "Good job Moe!" You laugh, and she smiled. "This big guy here, is gonna be much...much bigger. He's gonna have a nice...big girl to play with him too..."
Eventually, the sex began after some foreplay. She road you wildly, and was soaking wet down below almost from the start. You barely even did anything, she did all the work, bring you both to an extreme orgasm, letting you know before hand she was on the pill, and completely clean. Good...if she wasn't you'd move to Mexico.
Anyway, a few seconds after the orgasm, both of you breathing hard, you noticed the change start already. You looked at her body inch upward a few inches, and she looked down at her breasts as they expanded slightly. You felt you still erect penis swell larger inside, and saw your pecs take up a bit more of your vision as they grew, and felt your feet grind against the floor as your legs lengthened slightly.
Sarah was speechless...
