I'm closet bi, leaning straight. But my younger brother is a fully gay femboy, and has basically been my personal cumdump ever since we were young.

He's actually the only guy I've ever gone all the way with... so far I've only dated girls. I don't hook up with my brother nearly as often now, compared to back when were horny teenagers sharing a bedroom. But I still give him booty calls when I'm between gfs and need to get my rocks off.
