A guy gets to experience the ultimate threesome. Ashley rode my rock-hard cock, moaning like a banshee with her huge tits bouncing in my face. Ashley was my girlfriend, and she had always been somewhat of a nymphomaniac. She was 19 and I was 21 and I had snagged her when she first came to college. As she rocked back and forth on my lap, I was rubbing her pussy with the thumb of my right hand and squeezing her melons with my left.
