Dream

Ask him what he thinks about your mothers body? Ask him if he would ever fuck her. When he Higgs her goodbye make sure your friend lets your mother feel his hard cock pressing against her. Maybe ask your mother, if she knows why your friend’s cock is so long and thick.

Invite your buddy over, ask him to seduce your mom. See if she takes the bait, the sit back and watch! If it's a no, keep inviting him over and flirt with her. My wife loved my sons friends he'd bring over after he graduated and was in college. We both played with a few of them. Smoked some weed and we both fucked a few of his friends. He was mortified when he found out we fucked one of his buddies. So we give him some extra funds to use when away at school and he brings home fun toys for us.
