Too bad the top didn't reciprocate the oral. Fat guys have really sexy penises, usually small and can cum quite a large load. I'd have taken my time and sucked the chub with LOTS of eye contact and moaning, telling him that I want to swallow his cum. It's worked for me in the past with several chubs who were initially too shy to expose their penis because they felt they were too small. One chub was 4 inches and cut, not small in my book and I made love to his penis with my mouth like I was starving. He must've cum a half shot glass worth of semen into my mouth, which I swallowed. Was really sad when he moved away, we had a nice relationship going and I had developed feelings for him.
