It's your birthday, son. And Mommy wants to give you a very special surprise. Mommy's seen the way you've been looking at her lately. Mommy's also seen the growing bulge in your pants when she has a nip slip or bends over in a short skirt. I think you want Mommy just as much as Mommy wants you. So come on, let's give into temptation. No one will ever find out. It'll be our little secret. Mommy will start out by giving you nice sloppy blowjob. Then Mommy will straddle your cock and ride you, cowgirl and reverse cowgirl. Finally Mommy will get on all fours so you can pound her pussy doggystyle. Happy Birthday Son, I hope it was the best birthday ever :)
