This elicits another giggle from all three of them as they wander onward.That was cute, I guess. In the weird sort of way I’ve come to expect since...my arrival. I half roll my eyes at the peculiarity, but really I’m just letting them lag behind me as I turn toward the stairs. As luck would have it though, they stay in range of my ears for a while. The stimulation of their giggles and knowing that they are both naked and that I find each of them very appealing is eroding my control. That guy. Just before I left, my wife had asked her mom to help her into the bathroom to go pee and to get a quick bath/shower. I took my queue and I left.I returned home about 3-3.5 hours later to find the two women sitting in the living room. My wife saw the look on my face and she asked me to sit in a chair they had brought into the living room so we were arranged in a triangle. She proceeded to explain to both of us her new rules for the house:1. No more secret sex. For any sex to take place, all 3. He commented that nobody had done that for him before. My mouth started to get sore as he was so big, and he was being quite dominant by pushing my head onto him. I said my mouth as starting to ache but he said that he didn't care and that I should keep going.I continued to do this harder and faster for almost half an hour until I felt him move towards orgasm- I also looked down at my engagement ring a few times and felt very naughty. But just before he came he asked me to stop- which was just. " She said. I noticed that she was sitting in bed, with the covers pulled up to her neck. "Being with you tonight was just so wonderful. And I don't know what came over me, teasing you like that." I don't know, I thought it was quite sexy, really." I countered."I wasn't sure if Marianne, really saw me or not, but if she did, ... I am simply mortified!" Oh she definitely noticed it." I told her. She looked shocked and a bit panicked. "She told me though that she thought it was very sexy." Mom.
