She slammed her legs together, got completely red in the face, and with her rock hard nipples, knew she had to accept an ultimate dare. Her younger si...ter piped up and said, "I have two more clothespins!" We agreed that she had to put on the clothespins, but this time with no shirt on. She complained a lot, but ultimately did the ultimate dare.So here we were, Sarah with clothespins on her nipples through her shirt, with her hand in her panties, and my older cousin with her shirt off and. I told her that what he felt was normal as every teenage boy went through phases like that and that he was much too young, but thanks anyway. She smiled and just said "I don't know, but I tell you mom, he's really sweet and very mature. He is also incredibly cute". We left it at that.Over the next couple of weeks Mark came by to visit my daughter more often, all the time watching me very intently to the point where I couldn't help but stare back. I started thinking about him a lot as time went. It was hard not to give into temptation and then I understood. She didn't make any gesture to ask me go between her legs so I simply knelt in the slave position that she had taught me, my long hair all around my body. "Little slut. Don't you like your Mistress’s pussy?" she queried. I shivered and feared that I had made the wrong choice. My tears were drying now and my butt was starting to recover from the earlier punishment. "This slut love Mistress’s pussy and she hopes she can eat it. Throwing your head back and moaning loudly you start to run your fingers down my chest, they leave their mark but with little pain, the sensations we both feel are amazing and it takes all my strength to not explode there and then. I start thrusting up and harder than before and you squeal as you feel my cock reach new depths, going farther then ever before, you reach up and grab my neck lifting yourself slightly, I pound again and again as, yet, another orgasm washes over you and soaks my cock.
