I met my neighbor on the street and we started to talk about something very intimate. We talked about our girlfriends and their sexual desires. Suddenly, she suggested that we simulate lesbian sex, and I agreed. We went to my apartment and started to act out our fantasies. My girlfriend was at work, so we had no one to disturb us. We took off our clothes and started to kiss each other passionately. I put a strapon on her and she began to fuck me with it. I moaned loudly from pleasure, and my neighbor liked it very much. She continued to fuck me with a strapon until I reached orgasm. After that, we both calmed down and talked about how hot our lesbian sex was.
