On the way up to Montana, my mother seemed happy, content and despite the long hours, knew it was something she wanted to do. More often than not, we ended up in a less expensive hotel with one queen bed. We'd change in the bathroom when the other was showering and crawl into bed, happy to sleep after the long day's drive. On the way home, it was a different story. She seemed sad, forlorn and somewhat maudlin. She talked little, and when she did it was sort of negative-nothing terrible but contrary to her normal happy self. After several grueling days of driving home and having nearly run out of money, we decided not to stop for the final night and simply drive until we got home. Exhausted, hungry and just needing sleep, my mother went to her room, stripped to her bra and panties (she still wore a bra around me, even though her perfect C cup breasts had practically no sag), and crawled into bed, sliding in next to the wall and covering herself. I brought her a glass of water to put on her nightstand and lying down for just a moment, only to fall fast asleep.
Sometime in the middle of the night, she must have stirred. I awoke drowsily to realize I had turned to hug her and one of my arms was over her, the other under her, reaching around her neck. My hands were warm and nearly cupping her breasts. They were sort of bent in that way, but not actually cupping her. I didn't want to anger her if she woke up and as I tried to move them away, it was obvious I couldn't really do it without waking her up. Her arms were folded slightly in front of her and moving my hands would have meant pushing her arms out and up to extract myself from the slightly sexual pose. Before I could make a plan, I had fallen back asleep.
A bit later, seemingly just before sunrise, I felt movement against me and awoke for a second time. My hips were pushed against my mothers. I was hard. Now my hands were planted on her breasts and she was still fast asleep. Despite trying to remain calm, I could feel myself becoming hard and was soon erect, my cock pressing against her backside, the soft panties only making my concern grow. She moved a bit and I found myself slipping just under her ass cheeks and the shaft of my cock, nestled tightly in my underwear was sliding between her legs, the head bumping up into her...well, I assumed her pussy. Unable to control myself at this point—there had been almost a ten days of having no time to myself to jerk off—I rubbed softly against her. As my cock slowly peeked out from the waistband of my briefs, I could feel her skin slide against the head. A few more gentle pushes and my cockhead was nudging her panties to the side. I kept telling myself to stop, but at that age, your hormones more often dictate your behavior than your brain. I was inside my head at this point, enjoying the sensations of my mother's soft skin on my cock. I worked slowly, her panties giving way and I felt something moist. Soft. Almost unbelievably sexy. It was my mother's pussy. Feeling the heat, I pushed just a bit more and she awoke with a start. It was too late. I was caught. And I was just inside of her pussy lips. What happened next, I had never anticipated.
