Part One:
The date was going great. The horror screening was nearly deserted, and me and my date found a dark place at the rear to make out. I made sure to sit with my step-brother clad legs up on the seat in front so my brother had a great view of the grisly murders and jumpscares on screen. It sounds cruel but if I didn’t keep his heartrate up he’d transform back, and there was no way I was getting caught naked in a movie theater. It worked like a charm, the horror keeping his MMS fight-or-flight response permanently triggered. I know how much step-leggings hate horror.
Sitting with my legs high and spread was like a red flag to a bull for my date, and he soon had his hands all over me and my brother, stroking my ass and thighs, his fingers rubbing against my moistening pussy. The movie faded into the background as we lost ourselves in the moment. It wasn’t long before he lifted me into his lap and I was grinding my leggings-clad buttocks against the cock he’d pulled out of his pants, holding my moan to stop the old couple two rows in front from noticing. In my defense, as he blew his load all over my leggings, I’d forgotten all about my brother by that point, remembering only as the cum started to soak into his fibers.
“I just need to go use the bathroom,” I excused myself, hurrying to the bathroom to at least towel him down. The moment we got into the calm, quiet, empty stall of the women’s bathroom, he started trying to change back! My leggings rippled and turned a shade of skin! I needed something to stop him relaxing, something to kick his MMS into overdrive, and fast.
“If you even think about leaving me here naked, you little shit, I’ll tear you into rags and leave you in the trash.”
I wasn’t proud of what I said, and I didn’t mean it. But, hey, it worked! It’s been hours since I got home from my date and he still hasn’t changed back yet.
Maybe I went a little too far…
