The thunder is getting louder and flashes of lightening outside briefly light up the room. I stand still and allow you to glide your pussy on my wet ...cock. I look down and notice that my cock is covered by your wetness as I watch your pussy lips glide along the shaft of my cock. The storm outside is getting intense, as is the speed in which you are riding my cock. I reach around you with my arms and take your tits with their hard nipples in my hands. I see that your knuckles wrapped around. Both of us unsure of what to do. Luther’s words ringing in my ears, about how his hobby was exploring sexuality and that he hoped Jill and I would be Dee and his ‘playmates.’Fuck!All my alarm bells were ringing again. Shrieking at me on full volume, like I had a station of fire tenders in my head. Telling me that if I gave Jill the slightest encouragement or sign of approval, there would be no going back. We’d have crossed another Rubicon and be headed down yet another slippery slope into I. But now that you and I are having sex..” there wasn’t a hint of shame in her voice as she said those words out loud for the first time this whole week, “we need to decide what we’re going to do. Because if you’re going to continue to sleep with me and her, It’s only fair to let her know.” She was right, but I was dreading this. “Well she doesn’t know about Lyla and Shelby either…”“Then you’ll need to tell her.” She said, sounding more like a mother than ever.“Ok...” I looked down at my hands. There was no longer any awkwardness about it. This had also made me more confident during my daily blow jobs. I would regularly look her in the eyes, it let me know that she WANTED to suck my dick, she WANTED to please me. During these I thought of her as MINE. She was still my mother the rest of the time, and I respected her as such. But when she would come into my room, she was there for my cock, she was MY SLUT. She had actually encouraged this. She told me to do what I wanted, and what felt.
