Stepdad Eric John Catches Stepson and His Girl Then Joins the Action Himself

My wife is pissed because she caught our stepson trying to have sex with his girlfriend under our roof and expected me to deal with them. Oh, I was going to talk to them, alright. I was also very mad, fuming, and disappointed, but not because they wanted to fuck. I was frustrated because my stepson had no idea how to do it! As his stepdad, I can't let him embarrass himself like that, so I made a deal with both of them: I would let them have sex and even teach them how to fuck, with only one condition: don't tell Mom.
