Take a look

"What do you mean it's gone?" I squeaked grabbing at the lacy fabric.

"I mean it's gone" Todd answered slowly and carefully like he's explaining to a idiot "Your cock and balls sort of sucked inside and now you've got a pussy, pretty nice one too."

"A pussy?" I protested  "That's crazy talk I cant have a pussy I'm a dude!"

Even as I denied it I noticed how soft and full my ass was feeling. In fact, my whole body was starting to feel very odd.

"No I don't believe it." I continued to object to the evidence of my senses "There's no way wearing a pair of panties could actually turn me into an actual girl. This is just some kind of weird vivid hallucination. That's it it all in my head. I'll... wait what are you doing ?"

At some point during my hysterical rambling Todd had shed his pants and was stroking his thick cock.

"Put your pants back on... No! Stop!" ignoring my protests he took a firm grip on widened hips and with a single thrust plunged into my new formed cunt.  "Ah...! It's in me your cock is really in me."

"Yeah, no shit you dumb slut" He grunted in response to my statement of the obvious "Why else would I trick you into wearing a pair of cursed panties? Now stop whining and take it like the bitch you are."

"Oh! Oh! Okay... I... ah!" I moaned as unexpected waves of pleasure swept my body. Maybe I should have felt insulted or betrayed as he fucked me roughly from behind but instead I felt only acceptance, "Okay, I believe you, this is really happening. Just don't... oooh, don't you dare stop!"
