I get real hard when being fucked, cock bounces around stuck out in front dripping precum which flails around in long strands, some guys scoop it and use it as lube, others like to see it bounce n drip.... a good top will position me well and watch as i cum hands free, i can feel his cock swell as i shoot my load, they usually follow soon after! Never had a guy worry about my big cock.. its not always the size that counts, its what they do.....
