The fucking just started getting really good when he shocked me by putting his hands around my neck. At first, it started out like a grinding massage. With each thrust, he squeezed a little bit more. I started to panic a bit and he whispered very soothing reassurance in my ear to relax me.
I closed my eyes and enjoyed the pressure. He squeezed some more and fucked me harder. With each squeeze, I could feel myself tighten up inside, closer and closer to climaxing.
Right as I felt like my lungs were going to explode, from not being able to breathe, I had a very earth shattering orgasm and squirted all over his cock.
Sadly, I passed out and missed part of it, but it was still fabulous! I do believe Sexual Asphyxiation is one of my new favorite past times.
