Son Got Aggressive, We Had Sex

I wrote a couple of months ago about my son’s ongoing fetish with jerking off into my panties and swimsuits. It got worse. I’ve been very mindful of my son not tormenting his sister, but I have let him use my underwear for his habit. Not really “Let” so much as didn’t say anything anymore.

First we had to go to a service for church. I had on a dress, nothing too frumpy but definitely not what you’d call trampy or overly sexy. It was fitted though, so I went with a thong. We were waiting in the lobby of the church after service and it was packed (COVID be damned, right?)… My son stood directly behind me and on a few occasions the group would compress. First time we bumped I didn’t think of it, second and third same thing, then the fourth I felt my son’s erection jabbing me in the ass cheek. Then again. Then I felt him run a thumb over what would be the waistband of my thong, and he TRACED IT…he ran his thumb along the thong until it met my ass crack. He pressed his thumb to my crack and I looked back and said sternly through my mask “Careful!”

My husband and daughter were both talking to others with no signs of leaving soon. I walked over to my husband and said I’d start the car. My son and I went to the parking lot and got in the car. I immediately yelled at him for what he had done, and he responds by asking “Can I see your thong? Can I use it?” I was shocked and asked “Here, Now? What is your problem?” “Please Mom,” he says, “I can’t wait.” He begged for a few seconds urgently. I know how unbelievable this is, but in the moment I was so flustered that I looked around to see no one was looking (it was dark outside) and I pulled up my dress enough to pull off my thong. I handed it to my son and watched him in the back seat as he first sniffed and licked the crotch and then jerked off in my thong. He asked, “Are you wearing the matching bra?” I was startled he knew the underwear I owned and said “Yes.” With that he blew his load in my thong and HANDED THEM BACK. “Please wear them.” He said. Even more shocking that I think of it now, I put it BACK ON! I sat with his fresh sperm in my pubic hair while we sat in silence waiting to go home. I was mortified.

I got over the church episode over the next couple of days and found fresh sperm in my used underwear the next two days. This is normal now. I wanted everything to be normal and outside this issue it was, but isn’t now. It was New Year’s Eve. We were watching a movie I never saw before but the family had. When midnight hit, we cheered and hugged then my husband declared he was off to bed. Soon after, my daughter said “I’ve seen this before” and went to bed, too. I didn’t feel nervous being alone with my son, until a few minutes went by and my son asked, “Mom, I love you.” I said “I love you too” then he sat aside me on the sofa and gave me a hug, and I hugged him back like a mom. He shocked me again when as we hugged he took a hand from my shoulder and put it between my legs to rub my crotch. I had on yoga pants with panties and baggy sweatshirt. I flinched and said “What the hell?” pretty loud. “Shush” he told me, his hand still planted on my crotch.

“Stop it right now.” I said, but he just dug his hand in against me, leaned in and kissed me. I stopped that right away. “Please stop this now.” I ordered him. “Please let me use your panties again.” he pleaded. “No” I said as he pressed his thumb to my crotch through my pants. “I have to, Mom, I have to.” he said. He pushed his other hand behind me and pushed into my pants, pushing a finger between my cheeks onto my asshole as he still thumbed my pussy, and kissed my cheek as passionately as he could.

I realize this sounds unbelievable and it could never happen, or I thought it couldn’t. But I gave in. I felt dirty with his hands on my privates. I said “Okay” and he withdrew his hands and leaned back while I pulled off my yoga pants and pulled down my panties. I handed the panties to him and he sniffed the crotch while I sat pantless next to him. He looked down at my lap and asked “Can I taste you?” “You mean me down there?” I asked in horror. “Yes, please Mom, I need to.” I responded “No!” in a strained whisper as he got off the sofa, knelt down in front of me. He pushed his knees between mine and I spread my legs instinctively as he knelt between my feet. He quickly kissed my pubic mound and waited while I spread my legs more and he began sucking and licking his way down to my clit. He passed it and without thinking I grabbed his head and said, “No, there” as I guided him back to my clit. He was sloppy, but he licked and kissed my clit as I first got very wet and then came on the sofa. I squirted, and I hadn’t squirted nearly that much in years.

On the sofa on New Years Eve I had sex with my son. I pulled him off my pussy after I came and I actually helped him slide off his sweatpants. I sat legs spread on the edge of the sofa and we fucked. When he entered he said “Oh WOW!” We sat for a minute both looking down at his buried erection. I could feel him pulsing and hard. “Oh My God.” He whispered as he began to pump long slow pumps. He didn’t last long. He buried himself in me and having him go in me caused me to orgasm again, making a loud slurping wet sound as I did. I left him finish in me as we just stared at each other.

We finished and quickly got dressed, except he held on to my panties after wiping himself. I felt the cushion of the sofa was wet from me and flipped the cushion. “Wow” he said again. I could tell, but asked “Was this your first time?” “Yes,” he said. “This didn’t happen.” I told him. “You need to find a girlfriend or do something because this cannot happen again.” He said okay but he put my underwear in his pocket. “What about those?” I asked and he said “I just need to keep them for a little bit to smell you, PLEASE?” I couldn’t deal with his begging so I left it go.

Nothing has happened since then and I’m trying to play everything as normal, but I’m still worried he will try something again. He hasn’t used my dirty underwear and hasn’t mentioned it. I know what I did is horrible. I was in shock but I know I should have stopped it. He is old enough, but still my son. I dealt with knowing his habits for over a year but he got so earnest with his pleading I just felt pressure, and now it’s much worse.
