I could cum in any second. You let go of my hair and my head falls onto the bed. Grabbing my hips so tight that I can feel your nails pierce my skin, ...ou fuck me relentlessly. Grunts and sounds of skin on skin fill the room. I can’t hold back much longer.“C-can I cum please?” I ask, as my hand shakes uncontrollably.“No, not yet,” You respond, breathlessly. “I’m almost there. I want you to cum with me.”I keep my finger pressed against my clit. The wait is excruciating. I push back against you. It hurt, but each little throb nudged her arousal, keeping it from completely dying. Her nipples ached as well, and brushing a finger over them shot a spike of pleasure through her. If she had been alone, she knew she'd be playing with herself."That chime lets you know you have to wrap things up with your guest," said Charles rolling onto his side and sliding a finger over her flat belly."Mmmm," she said. "Too bad. I'm sure we could think of more things for my Uncle to show me."He laughed and. She would swallow a little bit of it every 3 or 4 thrusts until I could feel only her mouth around me. Then she would open up to consume more of Kyle’s geyser as it drummed diligently against my manhood, keeping it nice and lubricated.Finally, Kyle’s stream began to peter out, and Diana tilted her head back for a third time to catch the rest of his flow in her mouth. As the last of it dripped out, there was a sudden stillness. The head of my cock was sitting idly in an open pool of pee in. He gave me a knowing look and asked " Are you ready for this? I think you know what is about to happen dont you ?" I just smiled and said "Yes please"With that he ever so gently pressed his massive helmet against my hole and applied pressure in a gentle but firm way.I had previously experimented with various things up my bum before, but this was the first real life cock, i was so excited and whimpered with delight as he entered me.For the next half hour or so, he humped me around that stock.
