Bench press.

She heads with you to the bench and has agreed to spot you. You only suggested this because you could stare up at her body the entire time. During your second set of ten she coughs to you. Looking down you notice that you have a massive erection.

“Sorry!” You stammer.

“Don’t be, I’m sure we can find a way to hide it.” Without another word she slides down the front of your pants pulling out your cock, and sliding aside the crotch of her leotard slides you inside herself. She sits on you lap with your penis inside her like nothing is wrong.

“Virginia? What are you doing?”

“You didn’t want people to see, and now they can’t. Can you squirm like that again? It felt good.”

“But- What about all the other girls?”

“They don’t need to know we can just sit here until it goes away or until I get you to cum.”
