I worked it in her hole and started pumping after a minute and we were both loving it after a few minutes I switched to her bigger toy. I lubed up thi... thick 8 inch dildo while checking out her cock trying to rip out of those cute little panties "start slow with the big toy at first". I worked an inch at a time in her tight ass for the first few minutes until I had over half in and pulled her panties away to let her hard cock pop out "stroke it while I fuck your ass". Then proceded to work up. Since she seemed to be comfortable and in a deep sleep I got brave and slowly worked my hand up her thigh to touch her panties. To my pleasant surprise she only had on a skimpy thong and I brushed my hand across her soft round ass. As I did this she moved her hand from my chest down to my stomach and squeezed me tighter. This gave me alot of confidence so I began rubbing her bare thigh.All of this had caused my cock to get rock hard. And now I could feel her lightly moving her hips grinding. "'Burgeoning: present participle of bur·geon.Verb: Begin to grow or increase rapidly; flourish: "manufacturers are keen to cash in on the burgeoning demand".' (I don't see where manufacturing has anything to do with my sisters tits.) 'Put forth young shoots; bud.' (She was already budding!)"So there!" Ricky is a smartass.Lookit ... if you want to tell this story ... get on with it."OK, I will."I wasn't expecting you to agree."David's sister, she of the bounteous boobs and shaved pussy..."Hold. I screamed. Lights flashed before my eyes as my legs went completely limp and numb. We both collapsed onto the bed with me still held tightly in his arms.It was the best, definitely the best orgasm that I had ever experienced. In realty being more precise, they were the best orgasms ever. The build-up had helped me to ride wave after wave to even a third, fourth, fifth, or sixth orgasm, each one gets somewhat smaller in magnitude, but still such a wonderful climax to my first cock in pussy.
