My friend tells me about this gloryhole and I decide to go during the daytime while my step-son is at school. I get in and see my first big cock , I suck it all sloppy and wet. After a few minutes he cums in my mouth and I swallow it. The second cock seems familiar but I don’t think much about it. I begin to suck and I pause in shock, it’s my step-son's voice... his cock is so big , I admire him and think to myself he can’t find out. So all I do is moan and groan and I give my step-son the best blow job as he finally cums all over my face.
