The morning after the party, I really wanted to jerk off. I turned on some good porn and got down to business. It turned out that during the masturbation, my best friend's sister, who spent the night with us, was watching me and came in at the most inopportune moment! This slut came in and asked me to fuck her! I did not refuse the lady and went on about it, fucked the beauty and filled her with sperm, she was happy!
