I was naked on my knees wanking my cock to a gay porn mag when the door flew open and my sisters bf walked in. He'd just showered and was wearing only a towel. I had not come out to anyone about my desires and felt so ashamed. 'Like that sort of stuff do you', he chirped and walked towards me dropping the towel. Inches from my face the invite was to great and I opened my mouth to accommodate him. He just laughed and barked, 'Dream on fag' and walked away leaving me in turmoil.
