Let me start off by saying I'm not proud, this story actually happened...

I (32F) am married and stepmom to two kids, one of whom lives with us most of the time because he (18M, let's call him Bruce) goes to community college close to our home while the 16F daughter lives mostly with her mom in the suburbs, where her school is.

A few months ago, my hubby took off to work early, just when I was hoping to get some action before he left. I got up, had some coffee and decided to take a bath. Now, we have a Jacuzzi and I had discovered a nice way to climax by facing the front of the tub and hover, with the water jet and bubbles hitting my vulva. I was horny that morning and quickly got close to coming, when out of nowhere Bruce started knocking, telling me to open the door.

Before I continue the story, you should know that Bruce is shy around girls and I had never seen him bring one home, or talk about them.

Anyway, I opened the door in my bathrobe, only to see him standing there, naked and with a giant, throbbing erection. I immediately slammed the door shut and yelled "what the hell is wrong with you?!!", told him to get decent and come back to explain himself, right now. Less than a minute later he knocks again, I open the door and his understanding of decent was a bathrobe with his still erect cock poking through.

Now, our bathroom door doesn't close properly, and we had been asking our landlord for over a month to get it fixed. Our temporary solution was a small hook screwed into the door that went into an eye in the frame. What I didn't realize is that if you pushed on the door a little, you could just about see the front half of the bath tub.

So it turns out our Bruce had been shamelessly spying on me. He confessed that it started with getting aroused from seeing my tits, ass and mound, then he grew a huge boner from seeing my labia, when I was bending over to feel the water temperature. Already crazy horny at that point, he started going out of his mind, just losing it, when I went on to pleasure myself. That's when and why he knocked on the door, and even now he was still shaking from extreme sexual arousal. He then started to beg me... "Now I've been honest, please, please let me put my penis inside you just once, I want to know so badly what a pussy feels like, I'm desperate" yada yada and he was not letting it go. "Come on, just this once, in and out, pleaaase, I would be so grateful, please do this for me, it's no big deal pleaaaase".

I still don't know to this day why I agreed to it, I should have just slapped him in the face to snap out of it, or something. I guess it was my still unsatisfied, ovulating vagina talking, and a massive boner right in front of me, his confession of lusting after me to the point of desperation. I was conflicted, could feel my pussy was begging for dick, but it was wrong. I finally caved and somehow told him he could push his cock inside just once, to feel what it's like, pull out and begone.

I dropped my bathrobe and bent over the sink, told him to do his thing. Not a second later he was behind me, clumsily trying to put his cock in, each time getting the angle wrong or poking my butthole. His legs were literally shaking from excitement, poor guy. Now I'm a fit 5'1" petite and he's about 6ft tall, so had to tell him to get way low, bend through his knees, and point his dick up. It was taking too long and I finally just reached through my legs and grabbed his cock, put it in on the edge of my vagina and told him to push upwards, gently. When he sank his rock-hard boner into me, Bruce looked and sounded like he was having a cathartic moment, a combination of intense pleasure and emotional release.

nd I felt a jolt of excitement as he parted my lips and his shaft slid all the way into my wet pussy. My hand was already there, I started touching myself, hoping he wouldn't notice. Instead of pulling out, he began stroking in and out, and once again I failed and let him. I told him something lame like "Okay, just a minute and that's it, no coming", not really sure it even registered.

Pretty quickly though, I felt an orgasm building. Being taken with such raw lust and vigor was a big turn-on, and his balls were hitting my labia and clit now. I guess I thought I could just push him off after I came, which was gonna be soon, but obvs I wasn't really thinking lol. I couldn't hide my pleasure though, he heard me moan and saw the enjoyment on my face in the mirror, each time he slammed into me, and I guess that was just too much for him.

Suddenly, he pushed his cock so hard up, it literally lifted my feet off the ground. He could no longer control himself, that little fucker was not gonna let me deny him the pleasure of coming deep inside of me, right there and then. His brutality sent me over the edge and now I was coming, while he shot his massive cumload right onto my cervix with short, forceful bursts. I was pinned down on his cock with no choice but to take it, and the intensity of my orgasm soared. After he had his way with me, he said sorry and ran off, leaving me standing there with his cum sliding down my leg.

I went to see him in his room, and made it crystal clear that what has happened was a huge mistake and it would never, ever happen again.

Even though I'm ashamed of it, I'm not gonna lie. I still think of the sex when I'm touching myself.
