Think of an excuse.

You decide to thing of something other than "I'm a sex species". You don't want artificial circumstances in this world. You want it to be as real as you remember it, but ten times sexier.

"I, umm I was, I tried" you mutter trying to thing of an excuse, as Stacy keeps squeezing and feeling your hand.

"Aww,John, you're as shy as ever. You don't have to hide it from me, it's pretty clear, y'know" she says, moving up and down your arm with her beautiful hands.

As she says this, your heart beats faster, and you feel a tiny bit of disappointment, knowing that things are going this fast, specially with Stacy. You wanted to take your time with her. It doesn't matter though, you still get to fuck her

"You know?Oh well, I guess that there's no use in hiding it anymore" you say calmly.

"Haha! I win! Ever since you walked in today, I knew that you were doing cardio"

Cardio? She thought that it was Cardio. Stacy doesn't know that you're a biological stud yet.

"Yeah yeah, you got me. I've been doing full body Cardio for the past few nights"

"Ooh! Full body! That means that your abs are pretty good too" she says, with the innocence of a child and moves her hand swiftly and lifts your shirt.

"Oh my God, they look so well sculpted. That too, you don't have a 6-pack, you have an 8-pack. That's so hot. Can I touch them? Pretty please?" she cutely begs.

All of this happens so quickly, the only reaction you manage to give is the tent that your cock is making in your jeans, through your torn boxers. You hope that she notices that soon too.
