Abigail was never late for these meetings.They'd worked out a nice system over the last couple of months. Abigail would come over after Allison got ho...e from school, usually about 3:30. Their brothers were doing spring weight lifting and wouldn't be home until 6:00. Neither would their parents, who were working. Jack had class until 5:00. That meant a nice quickie for the two sisters.They also worked Jack nicely into their system. Allison just kept hands off when Abigail was home during the. I laid on the bed, stocking cover knees on the floor and pumped the plug in and out, it was now on a really intense throbbing vibration and was pushing me close to the edge. With my other hand I touched by now bursting bell end it took everything not to come right there and then but I was wanted to do that over myself.Realising I was close I laid on my back, feet at the headboard, and walked up the wall, I knew I had a huge load and wanted to taste my hot cum fresh on my lips. So I laid hunched. I looked behind me in the mirror as best I could. It was a pretty solid knot. Victoria, outside the door: C’mon girlfriend, quit admiring your pretty undies, we don’t have all day. Crap. I wasn’t going to be able to get it off. Well, I figured that if I couldn’t get the corset off I might as well leave the panties and stockings on to avoid pissing her off, they weren’t that bad. I put my clothes back on. My jeans were dark and covered the stockings, at least enough that you couldn’t tell. She then drew away from me, taking the panties with her. Then, looking at my mom she said: “You’re going to have to have him tonight.” At this my mom turns red, and I see that even with that fearful face there is still lust in her look. She immediately bends over the edge of the bed, looks at me with the most innocent eyes and begs me:“Please fuck your mother. Make me your slut tonight.” My heart stopped as the adrenaline pumped through my veins at the sound of such words coming.
