I always thought I came from a normal home. My folks used to fight and argue in the evenings, then they would go into the bedroom to "make up". My mom was 5'3" and around a 135 pounds. My dad was 6'3 and 200 pounds. From what I saw in the usual course of home life, he was very well hung. The sex must have been great with them, even if they didn't get along almost any other time. Mom kept coming back for more and she never wasted an opportunity to get serviced nightly.
It was during the months before they got divorced that I found out that both had been swinging with other couples and mom had gotten jealous often.
I was 18 when they got divorced and mom was 36. She wasted no time in getting back into the dating thing. She was horny to the max and still couldn't get enough to satisfy her.
As I said, she was small and had a great body. When they were married, she used to wear a full slip and a light bathrobe over it around the house, but still occasionally, I would get a peek at her boobs and she frequently showed a lot of leg. As a very horny 18-year-old, I really appreciated a great body, even if she was my mom.
There were times, when dad was away on business, I could hear her in her bedroom after we went to bed, accompanied by a low buzzing sound. More than once I peeked in hoping to see something erotic, but never got a good look at anything.
I was a strapping kid at 6'1" at 18 and still growing. Fortunately, I was hung like my father, maybe even larger
I noticed when they got divorced that mom spent more time with me and would have me go out in the summer and work in the yard or mow the lawn. I also noticed that she began leaving the robe off, and just wearing her slip around the house in the evenings.
I'd come in from working on the yard and shed ask me to fix a couple of steaks on the stove. She said I made great steaks. Then, she'd sit and talk to me and watch me cook. I usually came in without a shirt on and a little sweaty, but she didn't care. I could see out of the corner of my eye that she was studying my tanned and muscular back and abs carefully.
We'd eat dinner then watch some television during the week, but on weekends she'd usually go out drinking on a date. She always dressed well to go out on her dates. When she came home, she was either frustrated and drunk, or just drunk. I got to the point where I could pretty much tell if she got laid that night by her clothing and her attitude.
If I was awake when she got home, she would sit on the couch with me and watch the late show. Frequently, I'd have to try and hide the huge bulge in my jeans where my cock was trying to rise out of my waistband of my jeans. She would always go in and get into her slip before settling in beside me.
I decided to see what would happen if she saw me naked. That Friday night, I ran and got into bed when I heard her car pull in, then listened to make sure she was alone. She would stumble in if she had been drinking, then walk by my room and peek in the door. With the light behind her I could see her outline in the hall light. This time, I was prepared. I was naked under just a sheet, with one leg sticking out and my dick just barely covered up but erect, causing the "tent" effect pretending to be asleep. I could see her shadow in the doorway as she stood there for several minutes. I hoped she was looking at me and thinking about that hard cock sticking straight up under the sheet. She quietly closed the door and went to her room, where I heard the buzzing I used to hear when dad was gone. The problem was that I didn't know if that noise was because of me. So, I decided to repeat the experiment the next night.
Same thing as before, she stumbled in, then came down the hall to my room. I was in the same position with my leg uncovered and my cock barely covered but erect like a flag pole. This time, she quietly opened the door and staggered slightly against the door frame. I heard her tiptoeing into the room and could feel her standing over me. I kept my eyes shut, pretending to be asleep. I felt a gentle tug on the sheet as it slid off my cock, exposing it long and hard. She stood there for several minutes again, with neither of us moving a muscle. Then she moved quietly to the door, closing it behind her. Again, she went to her room and the vibrator started. This time, I crept out of bed to her door and heard moaning coming from her. I could have sworn I heard her say "oh, baby" several times.
