My Son And My Dirty Panties

I'm a old single mother to a 12-year-old boy. I haven't had sex or dated anyone in the last three years. Not only am I pretty busy, but I'm also very fat and unattractive, pretty butch-looking. Of course I don't like it, but it is what it is. Two weeks ago, I was putting dirty laundry from the hamper to wash and I noticed some white stains on my blue cotton panties. They looked like cum. I was surprised, sure I masturbate often (the only way I get off lately) but never in my underwear, and my cum is pretty much see-through. I had seen such stains often over the last year, but always on my son's own underwear and bed sheets. So I knew he was going through puberty, having wet dreams and masturbating, but obviously this was different. I shuddered when I thought that my son might have used my panties to jerk off. But I soon thought better of it. I felt like the last woman in the world anyone would get off on. And it's not like I'm the only woman he sees all day. He goes to school normally and has friends. And a phone with Internet access. I told myself maybe the stains were from a detergent from the last wash, or my son did jerk off in the bathroom but he simply took the first thing from the hamper to clean himself up later.


A week later, I was putting laundry to wash and I noticed that one of my panties was missing. It was definitely seven pairs when I put them in the hamper earlier that morning, not six. The black ones were gone. I figured I must be mistaken or I dropped them somewhere. I didn't feel like looking so I just put the laundry to wash. My son was in his room then, but I didn't think much of it. Later, I was putting some clothes back in my bedroom closet and I found the missing black panties there, on top of the pile of clothes. Once again, there were white stains on them. My pussy juiced up. I was both weirded out and aroused. It had been so long since any man desired me, and how could they? But that wasn't a man, it was a boy... my boy. My head was spinning.

The next morning, I decided to test my son. I was telling myself I just had to know for sure, but the truth was I missed the feeling of being desired sexually so much. It was Saturday and he was to be home all day. When he was in the living room watching TV, I casually walked in topless. (He had seen me topless or in a bra a few times before so I figured I could get away with it without making it seem weird or being too obvious, but the last time it happened he was around 10.) As an excuse, I mumbled something about being in a hurry and looking for a bra and a shirt. I tried acting like I wasn't looking at him and wasn't interested but of course I was sneaking peeks to see his reaction. As soon as I walked in his eyes nearly bulged out and I soon saw him adjusting his pants. Poor boy didn't even try to look away, he just stared at my big tits the whole time. My heart was pounding and I got so wet. I let him leer at me for a few minutes before I went back to my room. Almost immediately, I heard fast footsteps and the door to his room closing. I took my pants and underwear off and dropped to the bed butt-naked, furiously rubbing my fat pussy with one hand and groping my own tits with another. My clit was hard and standing up like a tiny prick, my pussy drenched. The thoughts of a man lusting after me, of making a man hard, making him cum, were just driving me crazy. I slipped two fingers into my sopping wet hole and pumped furiously, as I squeezed my left tit hard and leaned my head down to lick my hard nipple. I came hard, squirting all over the bed. I know it's wrong, but ever since then I've been masturbating to it over and over.
