When you hear someone having sex on the other side of a wall, you can’t help but listen in on the fun. I especially couldn’t resist eavesdropping when I heard my brother fucking his girlfriend in the next room. Sadly, I found out how terrible my brother is at sex. It was over very quickly, like I bet his girlfriend wasn’t even wet yet. The poor boy has no stamina or any idea on how to properly fuck a pussy. Since I am such a generous sister, I decide to help my bro reach his full potential. Don’t worry, we’ll get that cock working right. I will train you to go the distance and improve your sexual stamina. You think you know what being teased then denied is like? Well you are about to learn the hard way on what it truly feels like to be driven to the edge…
