She moan even louder. I stopped fingering her just long enough to unbuckle my belt and drop my pants. My dick was hard and ready. I grabbed her thong ...nd pulled her towards me. She let out a little yelp—I had pulled he thong so hard that it ripped and fell to the bathroom floor. Her eyes were blazing and her skin was flushed and red. I kissed her hard, spun her around, and bent her over the bathroom counter. I grabbed her hips and slammed my dick into her dripping pussy so hard my balls hit her. "Mark..." she drooled, a drivel of spit trickling out of the corner of her mouth. "This is so wrong...too much drink..." Mother..." Mark murmured, lifting his leg and spinning off her, making sure not to bang her in the face with his knee as he did. "My Baby..." she mumbled as she watched him spin around, crawling down the bed and back up between her lifelessly splayed legs. "Wrong..." She said.Stop now? He couldn't. They had come too far. He had to have fuck her.Her red, silk nighty was now. I love it. I want to get fucked every day”. Her words took me to the edge. I felt my balls pull up and my cock began to throb hard. I tried to stay still and let the wave go over me. My urge to cum subsided some but not all the way. I felt one strong squirt of cum bathing my s****r’s insides. I felt a second squirt gushing out and then it stopped. I kept fucking her slowly and my cock was just as hard as when we started. “Did you cum?” she asked. “Just a little”, I said, “I have a lot more for. She switched the tens timer to five minutes and walked to her seat only a few feet away. Before Cynthia could appreciate the music her nipples caught fire. She screamed into an empty bathroom. First her nipples burned, then pulsed... then the labia found pulsing stimulation. Her pussy flushed from the stimulation. Cynthia resented the involuntary responses of her body. She felt ready to cum... when...A man came into the bathroom. He took a moment to relieve himself... washed his hands.
