Suck his cock, its only polite to return the favour...

You get down on your knees and grab his rock hard dick and smile up at him. "Ready for the best blowjob of your Life William?"
He nods eagerly, wanting to see if you can deliver. You respond by easily taking his whole dick into your mouth and down your throat while your tongue shoots you and slithers across his balls. He´s taken aback by this and almost staggers as you start to bob up and down.

You actually have to hold him up after a while, but you do it with a twist. You reach back behind his legs and shove two fingers up his ass, while holding him up with them you also rub his prostate. Shortly after, he cums hard down your throat. His cum tastes a bit bitter with a sweet aftertaste. You slowly let it slide out of your throat while sucking all the way.

When you´re done he´s looking at you in awe. "That really was, the best blowjob I´ve ever had! Thank you!"
"You´re welcome. Now, for that hard pounding..." You pull him down on the floor and spread his asscheeks, then shove your whole cock down his hungry asshole.

"Ah, oh Gods! By all that is holy take it gently!" He pleads, but just like his mother, he will get no mercy from you. You immediately start to pound his ass hard, making your hips slap loudly against each other. Again, you cover your victims mouth with your hand to muffle their pleas.

He´s even more receptive than his mother. You milk him of no less than eight orgasms before you fill his ass with your demonic seed. As you pull out he slumps together on the floor, completely exhausted. As you lay down on the bed you see him fall asleep.

You pull his mother down with you under the bed covers and decide that its finally time to sleep. And in a bed no less, first time in your life.
