Fingers and tongues were really nice but a hard hot cock was simply the best. It was long enough to push right past my cervix and even though it was a...little painful at first it was such pleasurable pain. I think from that first fuck with Tony I became a slave to having a nice hard prick to play with. Having Tony cum in my cunt was also another sensation of sheer pleasure and I was fascinated at how long it took all the cum to dribble out of my fanny. It was still dripping down my leg an hour. “Vicky… get back up… sit the other side of mum… I want mum in the middle” Vicky clambered over mum and sat with mum sandwiched between the two young girls. “Spread your legs… lift them over Cathy and Vicky’s legs. I want to see that slut cunt spread.” Mum gasped, but lifted a leg over one of the girls either side of her nearest leg, her cunt was glistening with cunt juice… her lips parted wide showing the inner pink walls of her pussy. “Now masturbate” The girls looked in shock when mum slowly. And so that brings me to my story.Chapter One - "Dear Paul"I met Gerri about four years ago. We were both working for the US Census at the time. We started talking and hit it off immediately. We were becoming quite close and I was beginning to think that we would end up together when I met her sister Marie. Maybe met isn't the best word for it. Perhaps hit-and-run is a better way of putting it. She hit, then ran. But I am getting ahead of myself.When I was introduced to Marie she had just. It was so hot seeing the full size of the cock and the knot in Grants butt, I knew he would soon feel the heat of the cum deep inside him, Grant was pushing back so hard now. Both began to show signs, the dog sped up more, then with a loud growl his body shook, Grant also let out a loud moan as both orgasm. The dog filling Grant with gallons of hot cum, as it thrust forward pushing Grant into the wall, I moved to watch the knot as it held tight, cum started to drip from Grants butt, then Liz.
