[MF] How I found out about my GFs big-dick ex who she later hooked up with when we were on a break

I’ve been with my gf for over 10 years now and we met when she was 19. She was a virgin when we met and it was a good few months before we had full sex, but she did tell me that she had done some sex things with other guys before me. A few months later I asked her how many guys she had done sexual stuff with, and what kind of things. Nothing too surprising came of that conversation… she told me she had just one bf she was with for a few months, a few one night things and then one guy, lets call him BC, who she was seeing for a couple of months or so a little while before we met but never got to the boyfriend/girlfriend stage. In all cases they never did any more than oral and some dry humping / hands and that kind of thing.

I am above average in length and girth, but certainly wouldn’t consider myself as huge, but comfortable enough with my size down below. In my previous relationships I had always been the biggest they had seen IRL (Who know, maybe they were just trying to be nice…), but was curious one time so asked my gf how I ranked with what she had seen before. She told me she never really paid that much attention and that I definitely wasn’t the smallest, but there wasn’t much difference between my size and the guy she had been seeing before me so couldn’t really say for sure who was bigger between us and that she didn’t care anyway and that she liked my size. I left it there, and was maybe a little dissapointed I wasn’t for sure the biggest she had (which is stupid, as I was still the only one to actually have sex with her at that stage!) but didn’t really think about it too much more.

She is always amazing at giving head, and literally blew me away the first time she went down on me. She just seems to have a natural gift. One night we were quite drunk and as soon as we got home she started giving me one of her world-class blowjobs. She got me to stand while she sucked me on all fours from the bed and must have been super horny as she was really going hard and pushing me up against the back of her throat. Out of nowhere she pushes me right to the back of her and moves her head in such a way that my cock actually goes down her throat. She gags a little but goes straight back for more and eventually gets her lips all the way to my balls and lets me fuck her throat for short bursts in between her gasping for air. It was the first time anyone had deepthroated me and it felt incredible. I was so close to cumming, but managed to hold back and give her pussy some attention from my mouth while I let my cock cool off before we fucked.

For some reason while we were in bed cuddling afterwards I asked her if she he had ever done that with BC before. I’m not sure why I asked about him specifically, maybe just because he was the most recent she had been with, maybe something to do with the previous convo about size, who knows… She laughed at the question as if it was a really stupid question (I guess it was!) but quite matter-of-factly said something along the lines of “Hah, no! Ther is no way I could ever deepthroat him! So yes, that was the first time I’ve ever done it. Did you like it?”. I was a bit taken aback by the response, but let her know how amazing it was and went back to cuddling. Her response played on my mind, so I couldnt help but ask what she meant when she said there was no way she could deepthroat him. After that she admitted he was maybe a little bit bigger than me, so it wouldnt have worked.

At first she avoided telling me exactly how much bigger, probably because she didn’t ever mean to admit it to me in case I worried, but after a lot of reassurance that I wouldn’t care how much bigger he was and that my ego wasn’t that fragile she eventually showed me by estimating the size compared to me when I was hard. She put her hand at least 2 inches past the size of my erect dick, which she claimed “wasn’t much longer”! She also admitted he was quite a lot thicker and showed me roughly how much her hand would have wrapped around and it would have put him at at least 2 inches more in circumference as her fingers would barely have gone around half his cock (she has small hands, but her fingers just touch and no more when around me).

I eventually found out that she and BC had actually tried to have sex multiple times but it physically wouldnt fit inside her. We actually had a similar problem ourselves to begin with the first 2 or 3 times we tried, but once she became a bit less nervous and after a lot of pussy eating and putting her at ease, we eventually managed and she is definitely the tightest pussy I’ve ever experienced so I’m not surprised at all that they would have struggled when she was still a virgin.

Fast-forward around 5 years into our relationship, and my GF out of the blue decided she wants a break to have some time on her own as she is questioning what she wants from her future and for her life in general. She gives me the cliche “It’s not you it’s me” line and we go on a break but she wants a few weeks to figure things out before we make it official. I am gutted of course, but her mind was made up. We still keep in touch by phone/messenger etc but dont see each other for 3 weeks. When we do meet up she breaks down in tears, apologises for putting me through everything but assures me she does still love me and wants to be with me and says she was going through a hard time due to other elements in her life and just needed time away to figure things out. I am massively relieved and so happy to take her back. That night in bed, just as we were about to have sex, she breaks down again and admits she actually hooked up with someone. She tries to avoid telling me who to begin with, saying it doesn’t matter who and that there was no emotion involved etc, but after I insist eventually she tells me… Yup, you guessed it! B fucking C!! She eventually admitted they had sex dozens of times over that 3 weeks.

It took me a long time to get over the initial anger, but have now made my peace with it and we’ve been back together ever since. After taking her back I insisted that she tell me every single thing they did, as I needed to know the whole picture and didn’t want any surprises if I found something new out later. I also insisted that I see how their last messages went with each other, to confirm that things were over between them as she said. When I was looking through her whatsapp conversation I scrolled up and saw a lot of sexting and pics they had been sending each other as well as some explicit pics he took of them together and sent her. It was very intimidating and humbling seeing how much bigger he was, but it was true – she definitely would never be able to deepthroat him!

I’ve already written more than I thought I would, so I’ll leave it there for now but might post some details later if people are interested.
