I'm in love with one of my friends gf for a time. One night in a club they argued. She asked me to take her to my place and sleep together. After we went to sleep she started to stroke my arm. I asked her to stop, because a don't want to get hard. But she continued, and I got hard. She said we shouldn't let it that way. The next moment she was on me and we did it... on her period... Few weeks later she said, she only wanted a good f**k. I'm still love her. Even more.
