She has a surprised look and told me you mean to say that huge thing is yours, don’t lie to your grandma. I said I am not lying dadi, it’s mine. S...e asked me to show it to her, I was confused, I asked her is she serious. She said I am your dadi I have seen you naked 100 times now show me. I took out my cock from my shorts. It wasn’t erected but still, it was thick and almost six inches. My grandma said so it was really yours, do u take any medicine or what and I replied no it’s natural. She. The journey into Mark’s bed had been a long one, taking all but one year of my short life, but had been worth every awkward, uncertain step. It would soon be exactly twelve months since my brother’s erect penis had first entered my inexperienced teenage body – the first and only penis ever to do so - and our relationship had started in earnest.God alone knew how many times we had made love since then, in how many positions and places. God alone could count the number of orgasms my brother had. He was looking intently at her crotch. Then he moved his face down there, pushing aside her pubic hair with his fingers, exploring.Outside, the storm had cleared and the sun was out again, so he had sufficient light to make out her pussy lips and something odd, a nubbin near the top, like the head of a very tiny penis. He licked it tentatively.Tina gasped in pleasure. What had he done?Buoyed by her response, he licked it again.“Ooh, yes, like that...” Tina moaned, laying back and closing her. ....faster and harder, Her tits bounced at the same pace as his huge cock was pounding her now sloppy lose asshole. She rubbed her clit just as fast.......and still.....no sound from her.....not one moan.....not one whimper.....not a smile....not a gasp.....it was ......sexy. She took it like a trained professional. Then......I saw her mouth open......she mouthed the words "I'm Cumming"...that was it. Then without warning her hips bucked. She closed her eyes and her open pussy squirted all over.
