I was right…..Gemma and her Mum were up the garden. I climbed the steep steps up to the top half of the garden where they were. Gemma and Deb were b...sy making steps using some old quarry stone and chippings and soil. They were about halfway down so I started helping them.Gemma was wearing black ¾ leggings and a little red top that she’d pulled down along with her bra straps so that she wouldn’t have any white lines. Deborah had turquoise shorts on with a matching coloured little strappy top. My sister agreed as she also wanted to have a change. But I was not able to decide the topic. My sister was fast in these matters so she told “how about massage play?” . I supported her.So we removed our clothes and she went and lied on the mat facing her back towards me. The massage started from neck to shoulders, then her back, lower-back and thighs/ legs. I started applying oil inside the Butt cheeks. She started moaning.I was gradually kneading her butt-cheeks on the inside and also oiled. The upper North Shore Tudor-style mansion was massive from the front, well set back from the street by at least 100 feet of well-tended greenery with flowering shrubs and bushes hugging the front wall, while tall liquid ambar and English oak trees graced the perfectly mown lawn. The sly, silvery moon that glinted off the dark slate roof seemed to beckon the trio forward, but the back-lit limbs of tall trees threw twisted shadows on the ground that, though ephemeral, seemed to bar the way. Vague. Strong, long fuck. With short breaks he fucked me very fast. He knew how to hit sweet spots. We tried different positions. He knew what to do.Other: I pissed myself when he fingered me, he assumed i'm squirting and he loved it. I hooked up with him once another time and he tried very hard to meet with me more throughout my whole trip.Place: A rented bachelor flat surrounded by dense flora. Outside felt like a jungle. :) There was only one window, covered with a curtain so it was pretty dark.
