They couldn't mean...

You gag and sputter on the plastic dick in your mouth, pulling back. The girls look at you angrily at first, morphing into curiosity as your face shifts into that of desperation.

"You don't mean, you're inviting guys over? I can't let anyone see me like this!"

Your sister laughs, pulling out her vibrator and sauntering over to you. "Don't worry sissy, we know you're not ready for that yet. Tonight's just practice, we'll get to the real thing eventually." She flashes you a devilish smile before planting a kiss on your cheek.

Finding a surge of confidence in yourself, despite the strap-on that's still balls-deep in your virgin ass, you ask, "What makes you think I'll do anything like this again?"

Amanda laughs again, and shows you her phone screen. The video she was just taking is playing. Watching yourself twerk like you're on a stripper stage, how flushed you got. Then watching Lilly fuck you... it's almost like an amateur porn. You feel the blood rushing to your cheeks and to your member. It's not enough that your sister has video evidence of all this, but you get the sinking feeling that she doesn't even have to **** you now. You can't help but admit to yourself that you're enjoying this. You'll be damned if you tell them that though!

"Oh my god, her little pecker's getting hard!" Alex chuckles, then grabs your cock giving it a tight squeeze, "Are you enjoying all this?"

You hope it's just playful banter, but the expecting look from all the girls tells you otherwise...
