My new girlfriend was very fit thanks to one hour of swimming or Pilates every day. She teaches fitness classes in her free time. She is slim, well toned, a bit busty and had a few modeling jobs already for sportswear. In bed, she uses her pussy muscles a lot, for her it seems like a routine to grip so tightly and control the experience. The first few times, I was overwhelmed with the sensation.
She had me lie on my back and was about to ride me for the first time. She sat over my legs, naked, rubbing her pussy in preparation to mount me. I was enjoying the sight of her great tits and legs. I was a little worried about how long I would last with her setting the pace from above. She had forbidden me to use condoms and I knew it was going to be more intense than usual.
