Maybe because he was such a cool guy, handsome, smart, funny, wealthy and perverted. A perfect combination. I had turned him down on the offer three o... four times in the past. But now I trusted him. After those few times we met in his midtown hotel room while he was traveling.I didn’t feel as awkward as when he had first met me and we had a crazy afternoon/ evening of super-fetishy sex- stockings, garters, heels, bondage, lots of cock-sucking (mostly me devouring his huge dick - more about that. My hand was moving up and down the shaft of his cock real slow as I enjoyed the taste of his ass and balls. Soon though I had to have that hard cock back in my mouth. I slowly licked my way up the shaft of his delicious cock making sure I licked sucked and kissed each side as I made my way to the head of his cock. I took his cock into my mouth and wrapped my lips around it. I sucked hard and ran my tongue just under the head of it making flicking strokes with my tongue. I then opened my throat. My father was gone as well; I assumed he was drinking at his buddies like usual. I was still beaming from last night and took a long hot shower to clear my head.It was a little after noon by the time I was dressed and drove the fifteen minute drive towards Aunt Lisa's. I was nervous and felt a little guilty; I wondered if things were going to be awkward now. Things happened so fast last night and to make things even more stressful, mom saw me with a hard on. I tried to focus on the music. At about 8:30 we finally heard someone ring our apartment, and we buzzed them up.With wine instead of well drinks, the conversation flowed even better this time around. Before we knew it we were finishing bottle number four, all of us a bit tipsy. Sarah, clearly the drunkest of us, got up from the couch to use our bathroom, and I volunteered myself to go to the kitchen and grab another bottle. As I was pulling the chilled bottle from the fridge, I felt hand slap my ass and squeeze. I laughed.
