It's just natural." "Well, yes, it's natural, but, well…" "So, it's just natural that I want to help out my nice grandpa and help him feel better." ...But, you're my granddaughter, honey, we're related." Maybe I should tell you a bit about my granddaughter. She's 17, five-six, willowy blond, long, tanned legs, pretty face and a figure that must get lots of looks. Even I've enjoyed looking at her when she uses my pool, her bikinis are almost non-existent. They're thongs, even smaller than bikinis,. I could smell her sex, only inches from my face, and I couldn’t believe it when she started to play with herself. I leaned forward to lick her and enjoy her taste. Thwack! I reeled backwards from the slap she threw across my cheek. “Did I give you permission to touch me, slave? No! I don’t believe I did! Get upstairs and take your clothes off.” “Yes, Mistress,” I answered meekly, wondering where the hell this woman had come from.I got to our bedroom and looked at the bed. There were four. She was so lubricated with cum, I pushed my entire length inside her in onestroke.She gave a long, low moan as I filled her.Then I grabbed the soft sides of her ass and began to slide myself inand out of her rapidly, slapping hard against her cheeks, causing them toshake. Greg's cock slipped out of her mouth momentarily and her moans wereno longer muffled."Oh, oh, oh, oh, oh...," she cried, like a bitch in heat.I drove my huge manhood in and out of her eager snatch over and over,feeling like I. “Wait, let me,” she said, wriggling out from under him and in the same movement reaching out and opening the rear doors. David saw a figure stepping back as the doors flew open. He moved along side Ann, both on all fours, looking out of the rear of the van.There was a man standing by the picnic table, frantically trying to do up his trousers with one hand while in the other he held the lead attached to a medium sized dog.“Did you enjoy the show?” She said, making no effort to cover her.
