It's too fucking late for you to be pulling this. It's midnight and you're trying to sneak out to do what? Get some fucking head? Your girlfriend is such a whore.
"No, mom, you are. I saw those pictures."
Oh fuck... he didn't .... see those pictures I took for.... fuck. Someone that's not my husband. I need it sometimes... I'm a woman and son, I'm so sorry you saw that, please go ahead and sneak out and let's just forget about this.
"No mom. I was going to get head from my girlfriend and now, I'm going to get it from you."

My son shoves my head down onto his cock and down my throat, oozing cum immediately into my neck and leaving me a gagging, gasping mess. He's been pent up for a while.
This is when I realize, I'm in for more...
He isn't done with just one, he fucks my mouth and throat until he blasts another load on my face.

OK We're done, you had your fun.
I go to leave when he throws me over the couch and begins fucking my ass nice and hard, every once in a while pulling out to admire his work. Mom will do anything to get this over with.
I mean, if this keeps my son home and off the streets...
