Yea tell me.
We enjoy mfm with a guy we know pretty regularly. He's got a big dick. After maybe 1/2 hour of messing around, taking turns doing her in several positions it's easy to see him and her are "ready". He gets on top, starts to go to town with hard fast ball slapping pumping, she'll stretch her legs straight down, tense up had she cums HARD, her body is stiff as a board as she cums. That gets him off. It's so erotic and a huge turn on for all of us. He'll pull out and roll off, she looks at me, I climb on, slide in, she's SO SLIPPERY and warm. We kiss and pump slow till I cum and it is HOT.
We chat and rest for a few then we start again....good fun.
