Sigh and obey.

You sigh and look up into Rachel's imperious gaze. "Strip," she orders. You remove your clothes, embarrassed as you remove your underwear to expose your crotch to her. "Well, Parker, that's a pathetic little worm you've got there. It might make a nice clit though." She cups your erect dick and testicles in her hand and practically lifts you up by them until your mouth is near hers and she kisses you aggressively.

Releasing you, she yanks on your pubic hair. "You've got quite a jungle here. I want to see all of that waxed off." She lets go of your pubic hair.

"All right, Parker, bend over," Rachel says. You submissively bend over the bench for her. She takes the butt plug and massages it into your sphincter until the tip is well secured inside your ring. She then pushes it all the way in suddenly and forcefully. Your eyes and mouth fly open and you yell at the top of your lungs at the painful penetration of your ass. Rachel pushes her crotch up against your ass and grabs your hanging tits in her hands, twisting and pulling on your hard nipples.

"Oh," she says, grinding her crotch against your ass, "I can't wait to fuck this slutty little asshole."

She slaps your ass sharply, making you yelp, and struts off to her own locker. When you straighten up, you notice Julia staring at you raptly with her hand fondling her pussy. She quickly pulls her hand out from between her legs and blushes. You ignore it and the two of you finish dressing in silence and head out to the gym.
