“Oh! . . . so it’s ok for you to see your own son naked and see me get embarrassed about, it but not when it comes to you.” I then shut the door...and said. “You’ll have to wait then,” while I stood behind the door to see if mom would do it.Mom groaned again from behind the door..“Aaaagggghhhh! . . . . aaaagggghhhh! . . . I’m pissing myself! . . . ok! . . ok! open the door!”I opened the door ajar again and put my head around to see if mom was indeed stripping off, and she was. There she was on. I wondered how many other couples were tucked away tonight, warm and toasty, enjoying unspeakable acts of passion and pleasure. SMACK. I struggled to hold back the yelps and squeals that desperately fought to escape my tightly closed lips. I didn’t want to make it any more obvious that someone was spanking my ass for the pure fun of it. “Oh!” His hand fell again and again, the deep burning approached intolerable. “Aaaah!” I couldn’t hold back anymore. “Oooww!” The heavy swats came faster,. She hung there kinda of humping the air when he dropped his pants and started to rub his dick with one hand and he rubbed her pussy with the other. He was a bit wider then his boss but she wanted it bad, he just held his cock steady and she impailed herself and then stood there to get used to it. With no warning he started fucking he hard and fast, he held he hips tight and fucked her deep. she was screaming and crying. Then he came and walked away quickly. She stood there cum dripping out of. ” and I said “Oh” and I backed out through the door and I said “Sorry” again and he said “Don't worry about it”.So I closed the door behind me and went back downstairs to Cait's room and if I had been horny before I was burning up now and I laid down on Cait's bed and closed my eyes and I pictured his ass as I rubbed myself but then just imagining it wasn't enough and I just had to see him again and so I got out of the bed and went back upstairs and I carefully opened the door to the bathroom.
