"Of course!"

You lied. You didnt know if you were ready. You knew stepping through that door meant giving up any scrap of your masculinity you had left. Which probably wasnt much. You knew your first step in there was your first step into a new life of femininity. Your girlfriend opened to the door and you could see inside was all black. You start taking a step forward, and think to yourself that you can still go back. But you continue to walk forward. You walk through the door ahead of your girlfriend and she closes the door. Its pitch black. You feel a hand on your ass "this way" your girlfriend says as she parts a curtain infront of you.

You stand in awe. This place looks magical. Its got pink walls and beautiful pink drapery hanging from the ceiling. It almost looks like a princesses room, save for the walls and walls of sex toys. Your girlfriend starts leading you toward the counter. "Sarah, this is Harper. Harper this is my partner {sissy}"
"Oh its so nice to finally meet you, ive heard a lot about you. Welcome, welcome" harper says with a big smile and an extended hand. You notice she is wearing the same school girl outfit your girlfriend got for you. Your girlfriend whispers in your ear that this was the girl with the cock that she meantioned earlier. You grow hard thinking about the cock between her legs as you extend your hand for a shake.
"My, my, this is one cutie you got here. I wouldnt mind taking him for a spin myself" harper says, checking you out.

You get aroused thinking of the beautiful shemale infront of you taking you from behind. You get nervous and cant speak, you look over at your girlfriend and she looks back at you with a raised eyebrow. "You wanna fuck harper?" She asks "hmmm i guess that'd be okay with me, but im going in the back room. Ill try to wait up for you if wanna, or I could join you..."
