We're both 22 now, and since my twin sister and I graduated from high school we had only seen each other a few times. We never really got along becaus... our mother always gave her special treatment. I was always being reminded that she only wanted one c***d and I was the second born, so I wasn't loved anywhere near as much. A few months ago I had received an invitation to my sister's wedding and I was sure that I wasn't going. The 'emergency' call from my mother changed that plan entirely.I. The journey to Leicester was uneventful and the only thing that I really took notice of was how much Lauren and Becky could talk about things that I had little or no interest in. Oh, they tried to include me in their conversation out of politeness, but after a while I found out I could zone them out most of the time.“Either of you ladies need anything while we’re here?” I asked, as we drove into the services parking area.“Well, maybe I could just get a coffee and stretch my legs,” Lauren. She stood up, stradled her legs around his and he stopped her. He pulled out a condom from a bag he brought with him and put in on, then she lowered herself onto his cock. His face looked like he was going to pass out from the ecstasy, and I was now stroking myself in front of them. She was now riding him heavily and moaning with pleasure. I could hear the wet sucking sounds of his cock moving in and out of her extremely wet pussy and the sound of their skin slapping as she landed on his lap on. ?"I looked at my mom and I saw her eyes glaze over. I screamed in rage and reached out to push her away. Instead I found myself pulling my mother onto the bed with me. Far from resisting, Mom actually assisted me. In a matter of minutes I deposited a dose of sperm into my own mother's womb.Instead of jumping up and leaving Mom slowly dressed as if in shock over what happened. She then started pacing up and down the room, obviously trying to reason things out in her mind. I continued to lie on.
