My Secret Mom Kink: Sis Made My Fantasy Come True…

What was I doing?! My stepsister caught me jerking off to our stepmom's panties! I thought I was screwed, but she asked me to keep going. Was I turning her on?! Fuck, fuck, fuck. When she showed me her perfect tits and said, "They are just like our stepmom's," I knew she was being serious. She wanted me to fuck her! She wanted me to fuck her AND imagine she was our stepmom. She even put on the panties! I didn't think our stepmom would wear them later and realize they were covered in my cum. I was so confused. I wanted them both, and they both wanted... me?! My stepmom’s huge blue eyes, staring right into mine, basically begging me to fill her up… How could I deny her? I guess a threesome would cure my stepfamily obsession. It's worth a shot.
