A few minutes later mom walks out of the rest room and my jaw fell open. Mom was wearing a very short, very sheer, low cut nightgown that I had never seen. Her very large breasts (34D I later found out) were swinging freely in her gown as she walked. Her big nipples were clearly visible through the sheer material. Mom walked over to adjust the window blinds and as she reached up her gown lifted and I thought I could see the tip of her ass cheeks. By the time she reached the bed I had the biggest hard on of my life. She got into bed and laid there talking to me for a while. She then told me she was going to sleep, and leaned over to give me a good night kiss. As she did that her breasts almost fell out of her nightgown and I'm sure my eyes almost popped out of my head. She kissed me goodnight, turned to face away from me, turned out the lamp, and went to sleep.
I didn't think I'd ever fall asleep, laying there so horny. I thought about getting up and sneaking into the restroom to jack off but decided against it and finally fell asleep. Sometime during the night, I must have rolled towards my mom, and hugged her from behind. I woke up with my arm over her, with her arm on top of mine, and realized that my hand was on her breast. I tried to pull my hand away but couldn't because her arm was on top of mine. I didn't want to wake her, but thought that I was gonna be in big trouble when she woke up and found me touching her like that. However my hormone driven teenage brain thought what the hell if I'm gonna be in trouble, I might as well enjoy it so I started moving my hand slowly over her breast squeezing gently. It took a few seconds but then I realized that I wasn't feeling any cloth over her tit. Holy shit, her nightgown must have slid over (it was very low cut) and her breast was uncovered and I was feeling it. This was the first time I had ever felt a breast, other than a few times on dates when girls had let me touch them outside their blouses. (I think my early health problems, and delayed growth had made me very shy and awkward with the girls).
So here I am in bed with my mom, squeezing and feeling her breast, feeling her big nipple get hard, and her beautiful ass leaning against my crotch and my big hard on. I was in heaven, even if I knew the shit would hit the fan when mom woke up. Fortunately for me mom started to stir and moved her arm so I was able to get my arm and hand away from her chest and I moved away a bit from her. All of a sudden mom woke up, rolled on her back and looked at me to see if I was awake. She saw me and said good morning and asked how I had slept. The first thing I noticed as she lay on her back was that both of her tits were sticking out of her nightgown and both nipples were as hard as diamonds. I tried to carry on a conversation with her but it was hard. She figured I was just still half asleep and told me she was gonna get up and start breakfast, and I could sleep a little longer. I just nodded. Then she turned toward me to give me a good morning kiss and when she did her leg hit my crotch (and my big hardon). I'm not sure if I gasped, but mom got a strange look on her face and asked what shorts I was wearing. I told her it was my old gym shorts. She then reached out to my waist and tugged on the waistband of the shorts and asked how I could even sleep in these shorts since they were so small and tight on me.
I tried to tell her that they were OK, but she was tugging at the waist and told me I should take them off so I could sleep more comfortable. I tried to tell her it was OK, but she was insistent. I finally said OK and lifted my hips and she yanked down my shorts. As she did that the sheet and blankets flew off and with my shorts down my hard cock flopped out uncovered. Mom was looking down and I heard her say "Oh, you're not wearing underwear!" I started to apologize but she said no that's OK; the main thing is to be comfortable. I noticed that the whole time she was talking to me she was looking down at my cock. I also noticed that her nightgown had ridden up, and she wasn't wearing panties either. The sight of my mom's very hairy pussy (this was the 80s) made my cock jump and get even harder.
My mom asked if I was always like that. I asked what she meant, and she asked if it was always that big. Even though I was only 18, my cock was fully grown and just over 8". I told her it was only like that when I was excited. She asked if I meant like when I was looking at the magazines in my room. Busted, she had found my porn stash. I started to apologize for that but she said it was okay, and only natural to be curious about that stuff. She mentioned that the women were very pretty and could see how they would excite me. I told her she was prettier than all of those women and that's why I was so hard. She had a look on her face and then I looked down at her breasts and her uncovered pussy and she realized what she was showing me. She asked if that was really why I was so big and hard at that point. I said yes mom you're the prettiest woman I've ever seen.
She kept looking at my cock, and then told me that the only man's cock she had ever seen or touched was my dad's, and that I was much bigger than him. I said really, and she just nodded keeping her eyes on my hard on. Then she shocked me by asking if she could touch me. I asked what she had said. She told me again that she had only ever seen and touched my dad, and was curious now about mine since it was bigger. I assured her that if she wanted to touch me she was more than welcome to.
