The way my wife was tied meant that her ankles were almost at shoulder height and the barman leaned into them and wrapped his arms around her thighs -...this meant he could get leverage and he started to use this and thrust away. He slowly built up his pace until he was literally pounding my wives pussy and his balls were slapping noisily against her bum, and she was groaning at this attention. I had not gone fully soft after cumming and was now fully hard again and stroking myself at what I was. My cunt was gushing with juice and I felt the tension build as my orgasm was nearly on me. “I’m going to cum,” he groaned as I felt stream after stream of his hot cum fill my pussy. It drove me over the edge and into the strongest orgasm I had ever felt.We all came almost simultaneously. Joni and I leaned back into our partners. Cody wrapped his arms around me, and Frank wrapped his arms around Joni. We stood there for several minutes until we all had recovered.Joni suggested we go inside,. The bathroom is at the far end of the hall over the kitchen. Dad followed Mom up and some time latter he came back down.Dad had beaten Mom into the bathroom and removed all of the towels and anything else that she could use to cover herself with.Then we waited.Sure enough about an hour later Mom called, “Honey, can you get me a towel?”I followed Dad up the stairs. I had the video camera turned on and I followed him into the bathroom. Mom didn’t see me behind her because Dad was distracting her. "Let me check," I replied. I quickly walked back over to the rack and selected another pair. I was frantically taking stock of the situation in my head, thinking Ok, he had to have seen me looking at him. I hope he doesn't think I was gawking at his huge dick. I returned with the jeans and he stood there, only in a shirt, changing room door still halfway open. The rooms faced the side of the store, so it wouldn't have been in anyone's line of sight if they entered the store. Still, there wasn't.
