Your dick was feeling weird as you assumed that when dad was unconceived his egg remained in mom, and your balls got a load of cum shoved in them... and when you looked at your mom your dick was starting to get really hard as if the sperm in you was attracted to your mom... probably in number of different ways.
Shuffling over you asked "Say mom... Can we have sex? I think Dad wants to get in you."
Your mother chuckled a bit "No, you're a little too young and I don't think your dad would want to be an incest baby."
Your bulge in your shorts got more prominent "Um, I think that may have gotten him more excited."
"Ew, that's your member not him. That's it your grounded until further notice. Try cleaning your mind out." You'd rather not stay grounded, and you'd really rather not ejaculate your dad the next time you felt like jerking off. So with the remote in hand that was practically imperceivable to others you decided to.
