I was not thinking from the stand point that that was my son fucking, it was just a cock that should be in here…as I stabbed as deep into my pussy as I could while rubbing my clit with my thumb. XXX But…this short back and forth, his expressions and my verbal responses were in a playful mode. There was a large tub, big enough for multiple people, totally exposed in the corner of the room, right alongside a glassed in shower stall. Any thought of using the emotion of embarrassment on Mark was immediately dispelled when Mark walked in. Mark was peppering her neck, upper chest, with nibbling pecks. To heck with it, son or no son, I was not going to let him stop me. So my antenna never went up in defense so to speak. I just playfully smiled back. I dropped my robe and started to climb in…Mark was looking the other way.
