Fucking My Horny Stepson and Teaching Him How to Cum

I need my rest, but if my stepson needs me in the middle of the night, I'll always be there for him. This time, it was the smoke alarm keeping him up, so he wanted to crash in my bed. I knew the temptation of his body would be too much, but I agreed and tried my best to resist. Then, while we were resting I woke to the greatest sound I've ever heard: he was moaning, and his underwear was soaking wet. He was as horny as I was! It didn't take me long to understand he didn't know how to fuck or even jerk off, so this was my chance to get my hands on his big fat cock and teach him a lesson worthy of a great stepdad.
