I was just on a forum for people who like to watch eachother masturbate, and we were talking about what started our fetishes. This is my story.
i was dating the hottest senior at the school. one day, her and her 4 closest friends came over to swim in my pool and hangout. afterwards, when i was changing, i put on just a towel while i went to go get some water from the kitchen. as im drinking my water in the middle of the house, with my gf and all her friends there, my towel slips off, exposing me to them in broad daylight.
they all started laughing immediately and as i bent down to pick up the towel, i heard
‘why the fuck is your cock so huge?’
i stood back up, kind of confused by the question, as i have no control over genetics lol. But the question really turned me on, and literally within 20 seconds i went from full softie to throbbing hard on. i was looking at their faces as my cock rapidly filled with blood, and the reactions were priceless. they were giggling among each other, and my girlfriend who at first gasped, was now laughing with them.
