Found out why my girlfriend's ex couldn't let her go.
I really try not to be nosey about my girlfriend's sexual history, I'll start with that. Not because I was scared to hear about it, but out of mutual respect. I have my own history and she has hers, but when I found out about hers and one obsession that she had I couldn't help but see it all.
This started when we were grabbing an ice cream treat on a sunny day after being outside with our friends all day. Most of the girls were sitting at a different table from the guys, but we were close enough to hear some of each others conversation. Most of the guys talk was about our plans to take a trip to a friend's cabin that month and what we planned to do. Similar to that the girls were talking to our "friend" Liz and her recent dates.
Liz was not my favorite person, I'll be honest about that. She was loud and had a tendency to drink too much and talk about things that made most people uncomfortable. While she was eating and talking I overheard her talk about her most recent hookup, but more specifically how it ended. "He pulled out while I was ass up, flipped me over and came on my face. It was so much I couldn't open my eyes."
At first I thought most of the girls would be thrown off by how crass and loud she was talking, but I was surprised to hear a general "Hot" from them. Me and my girlfriend had done this early in dating, but recently and mainly I had only been cumming inside her. Because of this I was surprised to hear that she off all the girls thought this was the hottest thing Liz has said.
After leaving our friends and heading home I couldn't get the thought of her loving the idea of Liz having her faced covered. After a few minutes of silence I folded and asked her about it. She at first was shocked I even heard, but after thinking about it understood how loud Liz was. I asked her why she thought it was so hot and why we never did it. After a minute of contemplating her response she asked if I was ready to really hear that answer.
My heart dropped at first. Not in a bad way, but also not in a good way. After thinking about it I said yes. She told me "Do you remember my ex?" which is what you never want to hear. I said yes and she then told me that he would only cum on her face or in her mouth. On top of that it was always a lot, to the point that she couldn't finish it in one go.
At first I was horrified hearing this. My girl was used like that by someone else is never easy to hear at first. Based on my silence she immediately started to backtrack and apologized. I told her I asked and wasn't hurt by it and not to apologize. Her response was "don't worry he was a bad guy and would record it which I hated."
I blew it off and started talking about what to have for dinner. After a few hours, dinner and a few glasses of wine she went to bed. I couldn't stop thinking about it and it started to eat me up, I had to know. In a moment of weakness I opened her laptop which we used to watch tv on when the tv was in use. All I looked up was "Cum" and after scrolling past our own texts I saw what I knew was there. "Look how pretty you look with my cum on you" and I saw multiple pictures and videos of my girlfriend with her ex's cum covering her face.
On top of that were videos of her begging for it while sucking him. At first I was horrified and didn't know what to think or feel. Then I knew I had to bring it up to her, so the next day I opened up about what happened and apologized. She wasn't angry, but more confused asking me why and how I felt. I didn't know how to answer at first, but told her I thought it was hot to know that she was someone else's slut before mine.
To this day we still talk about our previous relationships and even watch old videos together.
