Description: Ive always been a bit embarrassed about cumming prematurely. I cant seem to help it. At school, during sex ed, I freaked the fuck out, and my bratty stepsis gave me shit for it. But our stepmom was much more understanding. Maybe a little TOO understanding. See Shes a sex therapist, and weve always been pretty open about things, but this went WAY too far. Soon, we were messing around at the house. As in, I was making out and feeling up my stepsisters boobs while mom watched. Id never been so hard in my life. This was fucked up, but for some reason it all felt so right Things really got weird when the three of us started masturbating together. Before I knew it. McKennas soft hand was wrapped around my shaft, and a handjob from my stepsis was just the beginning
