I was fucking my mother-in-law and my girlfriend caught us

I used to be one of those who got annoyed when old people started with their stories about things they did and how everything was better before. I thought it was something normal for someone who saw their best moments pass by. However, now I think I was wrong since grandma wanted to teach me how sex was done in the past. I have to say I am impressed. Both by the boobs of the old lady and the way she gives blowjobs. It’s all slower, but I have to say it is more enjoyable. Not being in a rush to penetrate her pussy is something I’m liking.
