This story is 100% true, but I am a little hazy on some details since it happened so long ago. I'm in my early 40s now, and this happened when I was I think 24-25 which puts her I believe around mid 30s at the time (my mom has a lot of siblings with her being one of the oldest, and my aunt being one of the youngest).

I had moved back in with my parents for a bit after I had broken up with my longtime gf,

and I find out that my aunt has been living with my parents for a while now (I think a year and change). Honestly,

I just did that math in my head now and I'm shocked how young she was. To me, she looked like an old aunt. Basically, she's not some knockout with big tits and a thin waste. She's fairly plump and ok looking;

nothing crazy. And oh yea, at this time, she was pregnant. Her husband had to move back to their home country so she was living with us by herself.

Over the next few months, as she got even more pregnant, she would wake up in the middle of the night to pee a lot or because she was just uncomfortable lying in bed. And at this time in my life, I was staying up late constantly, and I would typically end my day masturbating.

Unfortunately, I don't remember what possessed me to do it, and I don't think there was any real buildup to this other than I started to become a bit of an exhibitionist in my early 20s.

So one night, I'm having a particularly lengthy gooning session when at around 1:30am (this is just an approximation; I'm kinda guessing as I typically slept at 2:00-2:30am) I hear her go to the bathroom and then go back into her room. I stop in the middle of jerking off when I got the bright idea to ask her to watch. In the time it took me to walk to her door, I came up with a really weak excuse to get her to watch.

I knock on her door and she says to come in. I honestly don't remember if I made any small talk before but I end up asking her if she could watch me because I was worried that my ejaculation wasn't normal (yupp, worked really hard on that excuse). This is pure conjecture, but I think due to her pregnancy messing with her hormones and her being away from her husband, she actually said "ok, let's go".

We move to the bathroom which was right next door to her room. I proceed to sit on the toilet and she says "ok go ahead" with a very straight face. The look on her face really made me nervous; I've actually never been so nervous in my life so it was a bit difficult for me to get hard. I power through, stroking it and eventually get somewhat hard. Though I'm pulling on it frustratingly because I can only get it half hard and I really wanted to show my full size to her. (I'm only 5.5 inches to begin with)

So I'm stroking it in front of my aunt and I can't get myself to really look at her while I'm stroking it, which I regret. I only make passing glances and she's just staring at my dick while I stroke it with, like I said, a very straight face. My heart feels like it's about to leap out of my chest it's pounding so hard. Funny thing is I'm not nervous about getting caught with my aunt in the bathroom even though parents' bedroom is literally like a few steps straight from the bathroom we're in lol.

After about 5 min, I'm about to cum (even though I'm only half hard). I tell her in a very sheepish tone, "I'm gonna cum". She doesn't say anything, and I cum all over the floor. I didn't have the most mind blowing orgasm of my life because I was so nervous and only half hard. But I did manage to cum. She just said "ok, are you good?". I respond "yea" and she walks out of the bathroom.

And that's it, nothing too crazy and actually, pretty anti-climactic. But then again, this is real life and not some sex story trying to masquerade as a true confession.

P.S. Oh yea, years later, my aunt told my mom what happened. Surprisingly, my mom didn't tell anybody else, but just confronted me. Also surprisingly, she didn't yell at me. She just asked me "did you do it because you were being a pervert, or because you really had something wrong with you?" I explained that I really felt something was wrong. Again, surprisingly, she was perfectly fine with that answer and didn't even press me. I honestly think she just didn't want to think of her baby boy as some kind of pervert and is just in denial; that's why she was so quick to accept my explanation.
