"She responded pleasantly, "I'll call Cathy."Twenty minutes later, I heard the doorbell ring and went over to let Cathy in. Cathy was an average South...ern pretty teenage blond. She carried a backpack. "Please come in. Brianna is upstairs second door on the left."Two minutes later, they came bounding downstairs, towels floating behind them, and both in their "wear-at-home-only" bikinis.I went back to work. My office window overlooked the pool and I could, occasionally look out and see them. I. She was a bit taller than me, about 5’6”, slim but with great full tits, as I pulled her pants down I saw she had really good legs too, maybe needing a bit of toning and a wax, but she would be a hotty back in London. She had a thick covering of pubes, which turned me really on, it was like she was from an old 80’s porn flick. Aunty was still fully dressed, I quickly loosened her sari, under her blouse and petticoat she too wore a black bra and pants, she had a good body for a milf, she looked. Wanting to be a part of it, I reached up and cupped her breasts with my hands.It was the first time I'd held another woman's breasts. I'd limited my groping in the pool to sides, back, and butts. I liked caressing her breasts. It was kind of like feeling my own, but different. Susan's breasts, being bigger than mine was a lot of that different, but still ... you know what I mean.I guess I was doing something she liked, because Susan moaned, "Oh yes!"Suddenly curious, I scrunched down, captured. I yelped through the mask as whatever was in my ass plunged deeper and seemed to me now half way inside my guts. In my numb haze I realised I was being fisted for the first time. I was on a high of lust, sex and gas as the intense feeling of fullness and invasion kept growing inside me. I could feel my hole being forced wider and wider. I knew it should have been painful but it was pure numb pleasure. I was hornier than I had ever imagined possible. Even the smell of my own shit only.
