At first I thought it was weird, but when my clit perked up enough to be rubbed as well I thought it was the best thing ever! Walking between shops ge...ting all rubbed up, and standing around browsing inside simmering down, and repeat.Until we had to go up some actual stairs (not escalators) and we'd run up the first lot to the half-way bit, and within about 7 or 8 steps suddenly I was rubbed right past that point of no return before I knew what was going on, and I got to the half way ledge and. The guy came into the room and I hered him getting undressed and he came over to me and grabbed my ass and squeezed it hard before spanking me only once.He then started slapping his cock on my ass before sliding it inside the panties inbetween my ass cheeks and he started talking saying how much of a slut I was and thats when I hered something move beside me. I felt the side of the bed lower as another guygot on to it. I felt his hairy body up against my face and what felt like a huge cock. When he finished massaging her back, ass, and the backs of her legs, he had her roll over so he could continue massaging her front. Mike started at her feet and slowly worked up her legs until he was massaging the tops of her thighs near her hips. He then moved up to her shoulders and continued there and down her arms.The whole time, however, his gaze was drawn to her tits and he couldn't resist their lusty attraction for long. He poured another layer of oil on his palms and then finally. She didn’t seem to notice my hands, but my active mind was starting to go down some naughty paths.‘Why was my ‘little sister’ wearing a sexy bra and thong-type panties on our hike? Was it an attempt to provoke me? Why was I seeing this new bolder side of Lisa for the first time in the middle of a park lake? Had she developed some kind of exhibitionist kink… and I was just along as a bodyguard? Or was this watery semi-public place a perfect spot for her to naughtily tease her ‘older brother,’.
