It's Valentine's Day and you're feeling a little jealous of all the gifts and attention that I've been getting. It just doesn't seem fair that your sister has to beat guys off with a stick (just kidding, I use my hand!) and you're all but ignored. I'm teasing you about it when I notice that you're looking down my shirt! As, is my brother all backed up? Well, it is a special occasion. Maybe I'll suck your cock a little. Oh my. It's so nice! Maybe I could ride it, too? I blow and fuck you, cumming on your hard cock, enjoying the kind of truly depraved sex that you can really only have with your sister. You know, I'm actually kind of glad that you don't have a girlfriend. More brother cock for me
