PIP/Shunned/Framing Noah
I felt myself getting closer and closer to cumming as I watched Noah sliding his dick around inside of Leah. Then, all of a sudden, just as I was starting to get close Noah slipped his dick out and climbed off of Leah. I saw between her spread out legs at her tiny pussy that recently had Noah's dick inside. My brain froze for a second, but then I realized the opportunity this provided me and pulled my 4 year old baby sister's hips up onto my knees and then pressed my dick right at her entrance as I gave myself a few more strokes. Between that and having my penis in contact with her pussy, I was pushed over the edge and began filling up her little vagina with the incestuous sperm.
I let out a groan and knee-walked away from Leah as a trickle of her ignored big brother's sperm trickled out from inside her. I admired the sight, but more importantly it was also noticed by my mother.
"Oh my god." She said, and then looked up at Noah. "You can already produce semen?"
She stared in disbelief between Leah and Noah. Meanwhile, Leah also noticed there was something running out of her.
"Eeeew! What's this stuff!?" She asks.
"It's... ahh... well..." Your mother seems to get completely freaked out. "Oh my god, first Jason and now this." She mutters under her breath. About the only reason you hear it is because she says it right after you stand up right next to her. "I... I can't handle this right now."
With those words, she storms out of the room, leaving a very confused Noah and Leah behind.
