I could hear her breath splitting and hastening and her moans which were signal enough that she was enjoying it thoroughly. We remained like that for ...lose to half an hour. I went behind her and began kissing the exposed skin of her back. She moaned, breathed deeply and made her back concave. I continued kissing and she was getting increasingly impatient. I sensed it and opened the knot of her blouse and kissed her where the knot had been "O...Oooooh!....hhhuuunnhhh" I thought that was the only. I had taken some similar pictures of my wife, but not with a dildo that big. It seemed to be as big as a wine bottle and the fact that I saw my sister in law positioned like that made me horny. I had just got a quick glimpse of the second photo when I heard Susan coming down the stairs. I could not believe that she had gotten dressed that quick. I just managed to close the pictures before she got into the room saying "I didn't want you to sit here all by yourself so I just dressed in the. I smiled, stood up, came towards her and pushed her to the wall and started kissing her. She kissed me back with the same enthusiasm. We started playing with each others tongue. I put my hands inside her top and started pressing her soft big boobs. Later on, she removed the top and started kissing me again. I held from the waist and made her lie on the bed. I removed my shorts and instructed her to blow me. Oh my goodness, she is a master in giving a blowjob. After around 5 minutes I came in. ? I explain to you. ?Of course, it wouldn?t do to put them in your hands and this solution not only stops your talking back but also puts your down a peg or two? Yea right, I hear you thinking. The only thing people see when they walk in to me is a girl dressed and cuffed like a runaway from a cheap prison flick with a stick in her mouth like a dog, drooling on my sweater. And it makes it impossible to ask by passers to uncuff me, in fact, it makes it impossible to say anything intelligible..
