Sex Practice For Sis

When I heard my sis break up with her boyfriend over the phone I had no idea she'd be begging for me to let her suck my dick. She said she needed to get better at sex and I was the only one she could practice her blowjob skills with. Damn, I just had to show this clueless slut how it's done and fuck all the memories of her boyfriend out of her pretty head. We both enjoyed it and she even learned how to take a mouthful of cum from her bro.
