I told her i had and suddenly my cock started to get hard thinking about that day. "Well i have been thinking about your penis" she sais,"And i wanted...to see how bigger it has gotten." Is it cool if I see it?" Luckily by then my cock had gotten very hard and i pulled back the curtain and there standing before me was my sister but grown up. Her blonde hair was the same but her tits had gotten bigger, at least a D cup and the nipples were rigid. She had a little bigger stomach but her pubic hair. The skin is now stretched to it's limit. She's now using 2 fingers, going in and out of you. You look down andcan't believe what you're seeing, her fingers disappearing into what wasonce beloved balls, and her thumb continuing to rub the tiny remnant ofthe head of your cock. As you feel yourself reaching the peak of thispleasure, you feel the skin give way, and her 2 fingers are nowcompletely inside you. You feel your new muscles contracting around herfingers in a body wracking orgasm. Any. She stroked every last drop out of my raging cock while I stroked those perfect thighs.When she was particularly horny, she would wear an outfit like this and make me take her to a bar in the nearest hotel. I got a room while she walked into the bar and trolled for pervs. The sight of her flirting with strange men knowing what she wasn't wearing under the outfit made me hard as steel. We always finished in the hotel room by ourselves turned on to the max.We repeated that scenario a couple of. She didn't finish him off, though and I was soon to find out why. Once we'd all got our breath back, Jon took me by the hand and led methough the lounge to a conservatory, where there was a bubbling hot tub. The tub was surrounded by candles, and all the blinds had been lowered, though I could see gaps of night sky, and wondered if anyone could see in from the houses opposite. Sonn had followed us. I was quaking. She had gathered some little pots of something, massage oils I thought they might.
