Jane and I were best friends but never exactly dated each other. We hung out with our friends, did homework and talked and had sex, which was a secret... kept between the two of us. I guess it was Jane’s idea that we could have sex with each other so long as one or the other of us wasn’t dating someone else. Friends wouldn’t be part of cheating was the argument and while it wasn’t all that easy for a teenage boy to understand I accepted it. Our senior year we both dated others off and on and I. I kept this slow speed up for a little bit with her moaning the whole time till she said, "Oh Jim, it feels so good like this and the shivers you are causing with your tongue going up and down my neck and back, but I need you to go faster."I made a couple more passes before raising up to see the trails I left on Beth's back and neck with my tongue and put a little more speed into my pumping in and outward in her pussy with my still rock hard cock.After reaching a certain speed, I held to it for. I was feeling her tits and they were quite soft to touch. She was responding with moans n groans and i was enjoying the feeling. In between all this, i managed to slip my hands in thru her top and started massaging her tits and also managed to get her out of the top as well. She had an off white bra on.. Nothing too sexy but her tits were definitely sexy… Perfect in shape and well rounded..it was like 34c. I was of course going wild and playing with her lips and sucking on her tongue feeling. Before i knew it i was naked and sara was still fully clothed. She slowly turned me around kissing my neck and shoulders then she slowly pulled my arms behind my back so gently i suspected nothing. I was sooo turned on at that point i didnt feel her put the handcuffs on my wrists I was shocked feeling the cold steel against my wrists i struggled before she took my ponytail in her hands and jerked back hard. Then she leaned towards my ear and whispered about how my sister had told her everything.
