Oh god. I never should've moved in with my sister, but after losing my job I didn't have a choice. I always heard rumours she was sadistic but had no idea of the truth, I haven't cum in weeks.
"Hey dad! My friend Riley is staying over for the night"
Uhhh honey, you know who this girl is right??
"Yeah of course dad it's Riley Reid. It's 2022 we don't judge women like that anymore okay? Anyway we'll be in our room, we'll try not to make too much noise and keep you up."
"Maybe your dad should join us"
"OMG Riley! You're so silly. Anyway, night dad!"
"Merry Christmas step-bro!"
"For your Christmas present you get to watch us make out"
Wait, what!??
"Hehe, aren't you so glad the three of us are family now?
"Hey wait a sec, is that a Christmas cracker in your pants!?"
"Oh oh! I wanna pull it!"
"No way I saw it first! Sit still bro"
Thank you Santa for giving me slutty stepsisters this Christmas.
"Cmon son aren't you coming out the pool for dinner?"
Umm, I think I'm gonna stay in the pool a little while longer mom
"Aww it's okay honey, you don't need to hide your little erection from me. It's a completely normal reaction. Now come on, stand up and show me what mommy's done to you"
