The young woman sandwiched between us. She really was quite attractive: 24, slim, tall, medium length hair. And when I put my arm around her back, the... let it slip to her waist my hand instinctively went under the waistband of her panties between her legs, my middle finger tracing down her spine, to the small of her back, sliding over her asshole, slipping into a very wet cleft. She only moved her hips gently backwards and without meaning to a second finger slipped in. She was still having an. So we slept with her facing the window and me on the outer and the curtain pulled as it was an AC 2 tier birth. We slept around 11.30 pm and I was holding her around the waist and she slept with her head on my arm. It was just like a couple. At around 1.30 she turned around and was facing me. We slept like that till 2.30 or so.I suddenly woke with warm lips pressed against mine and a tongue entering my mouth. It felt so warm.I sucked on the lips and tasted the lovely saliva from the tongue.. She came and slept aside me sharing the same blanket. We both said good night to each other and slept off.It was around 3 am I guess. I got up feeling something on me. Something hard hitting my face. And it was wet as well. I was too lazy to open my eyes and see but I came to my senses. And when I did I felt something else as well. I felt something wet right over my thighs. Which was slowly moving up towards my panty. I suddenly realized something was wrong and opened my eyes. I was taken aback. She lifted my left hand up towards thecollar then, and affixed the chain to that cuff with an identical lock.My hands where bound up next to my throat. The sensation of completehelplessness overtook me. I couldn?t do anything to protect myself,the feeling of vulnerability was exhilarating and terrifying. With melying back on the bed she curled up next to me pushing me further uponto the mattress until I was lying near the center of the bed.Karen started at my lips, slow kisses, gentle.
