For the next couple of weeks we continued to explore each other and get to know what the other liked and didn't like. So far there didn't seem to be anything that was off limits and my imagination started going wild. Once, while I was fucking Sissy, she mentioned that she'd like to have a cock to suck on at the same time as one in her pussy. I didn't feel like sharing her with anyone, so I ordered a dildo without telling her.
It came in a couple of days and I was shocked at how big it was when I opened it. It is about twelve inches long and almost seven inches in circumference around the base -- almost as thick as a soda can. It looks like a real cock and balls with a suction cup base. It has three modes -- thrust, wiggle and vibrate. I laughed at the absurdity of it but figured I'd show it to Sissy for a laugh anyway.
That night, when we went to bed, I showed her the dildo and we laughed but she also seemed mesmerized by it. She kept playing with it, trying the different modes. We tried the vibrate mode on her clit and she liked it so we kept playing with it.
She was lying on her back, holding the dildo with both hands against her clit as I was nibbling on her nipples. I was surprised at how quickly she was getting turned on this way and I loved watching. She started moaning and was starting to move the dildo from her clit to her pussy, spreading her juices around and slipping the cockhead in an inch or two, then three...
I was loving watching her, and was stroking my cock. I knelt up on the bed next to her and began twisting and pulling one of her nipples as I bit the other. After a few minutes of this, she said, "I want to suck your cock."
We adjusted positions on the bed, I slipped a pillow under her shoulders so she could look up easily and I repositioned myself so I was above her head. As she looked up, I slid the tip of my cock in her mouth and she began sucking while she resumed playing with the dildo.
She was now holding the dildo with both hands and each time she moved it from her clit to her pussy, she pushed it in a little bit deeper. She was spreading her legs as wide as she could while pulling her knees up on either side of her body. I had a fantastic view of her fucking herself with the oversized cock.
I latched onto both of her nipples as I began fucking her mouth, twisting and pulling hard, just the way I know she loves it. She was fucking herself harder and deeper with each thrust, she was now plunging at least six inches of the monster cock into herself.
I started copying the way she was fucking herself, fucking her mouth deeper and deeper with each thrust. I could now see her throat expand as my cock slid down it, then I would pull out to let her catch her breath before plunging back in.
Faster and faster, deeper and deeper, as she writhed in horny ecstasy, finally bursting into a wild orgasm. I pulled my cock out of her mouth and started jerking myself over her face. Finally, she screamed and pulled the dildo out of herself. The dildo was immediately followed by a gush of fluid from her pussy, spraying all over the bed, and herself. This sent me over the edge, and I unloaded all over her face as we both collapsed in exhaustion.
As soon as she caught her breath, she started wiping the cum from her face into her mouth, swallowing every bit. As she was doing this, I started licking up her juices that she had sprayed all over herself. I was clear this was her piss, and I couldn't believe how much it was turning me on to do this -- licking my sister's pee off of her soft skin! It was also a turn on that she squirts like that when she is having a great orgasm.
She was now watching what I was doing and she spread her legs and said, "That's a good boy, clean me up good now. Get every drop of my pee."
Now I know this isn't everyone's cup of tea (or pee), and it wasn't mine either until this very moment. It's just that the whole situation had built on itself, and I got carried away. But I loved it. A few minutes later we were stripping the bed and heading for the shower. And I slept like a baby again that night.
