Where does the mother/son bonding go from here?

They get REALLY close.

"Oh, no," screams Derek's mother as the immense demonic prick saws in and out of her pussy. "No, ohhhhhh!"

"Oh, yes, Mom," hisses Derek as he screws her roughly. "Your boy is fucking your tight cunt! I am going to fill your hot lewd body with jism, and it's gonna become hotter and lewder! You're my fucking cumdumpster, Mom! Like I always wanted!"

"Ooooooooh! Ahhhhhh! Fuuuuuuck!" screams the woman, rapidly falling to the Strain.

"Somebody needs to shut that bitch up," says Mick, apparently nominating himself for the job. He strides forward, and shoves his immense dick into her mouth. He and Derek roughly palm her jiggling tits, crudely manhandling her. You watch this woman's degradation at the hands of her own son and his best friend with a cruel pleasure, black pre-cum oozing from your engorged member. You're about to start wanking it when you hear a sound from the hallway outside.

"I better go check that," you note.

"Yeah, take it, bitch," snarls Mick. "Swallow that cock!" Derek meanwhile snarls as he ruts into his mother's overstuffed cunt.

You decide to take that as an acknowledgement.
