My Cheerleader Girlfriend Sucks Everyone's Cock but Mine

My girlfriend, the head cheerleader, would never give me any play. I got to touch her tits, but I went home every night and jerked off. When I asked for a blowjob, she said it was gross. She didn't do that. Then I caught her sucking my coach's dick and learned that the head cheerleader had responsibilities I wasn't aware of. She sucks cock for the coaching staff and the star players, but never for me.
