She did stir a little as my erecting cock opened and penetrated her, and I felt her nipple harden in my palm. But she made no effort to wake herself or signal to me that she was ready for sex. Nevertheless, there was no doubt in my mind that I was going to fuck her, regardless. I gently turned her a little more face down and scissored her legs to more fully open her sex to me. She didn't resist. I whispered into her ear, "Good girl" as I slowly pulled my hardness out of her, then thrust back in along my full length until I was rooted fully again. My God! I'd stroked into her just one time, and tight grip of her hot flesh was almost causing me to cum. Fucking a sleeping woman is so hot!
She had once told me that we were very fortunate that we were a perfect fit, sexually. My cock was long enough to bottom out inside her without exerting too much uncomfortable pressure, and it had enough girth to stretch her open almost, but not quite, to the point of pain. I'd heard that couples simultaneous climaxing was a rare thing, but we did it frequently, without even trying.
I was quivering madly inside her now, a feeling that usually drove her crazy, but she didn't move or speak. Obviously she wasn't going to take an active part in our sex this morning, but that was fine. She loved to get fucked while she was still half asleep. She said she felt warm and vulnerable and protected. She had told me that sex mixed with the half consciousness of sleep had created some of the most enjoyable orgasms of her life.
I wanted our coupling to last, but it wasn't to be this morning. This woman just excited me beyond control sometimes. The liquid squeeze of her pussy on my pole was forcing me toward an orgasm that I was helpless to prevent. Despite my keeping completely still, the uncontrollable spasming of my cock radiated nervous energy into my back and stomach and signaled an unstoppable climax. I tried to calm myself, but the muscle tension in my lower body grew tighter and tighter until it released itself and I plunged over the waterfall. I involuntarily drove myself high up into her and grunted as the semen exploded out of my body. I lay there helpless as wave after wave of almost unbearable pleasure coursed through my vitals. I did not thrust through my orgasm this time as I usually do, and I thought I could feel the heat of my sperm flooding back along my cock as I filled her to overflowing. I continued to tremble against her motionless body for a little while as my cock jumped and I emptied myself completely. The last thing I remember before I slipped back into sleep was her soft whisper, "Good boy."
