This happened a few months ago and its a pretty long story.
Me (M) and my girlfriend (F) have always been fairly kinky and open. After being together for years, we wanted to change things up a bit and try new things. Long story short, we found another girl to join a threesome and it was pretty great. We were satisfied and went back to our normal sex life. But after a few months my girlfriend suggested we should try a threesome with another guy. I thought it was only fair since we had one with a girl. She said she’d try find someone and I just left it as that.
I noticed the next few weeks, she was on her phone alot more, constantly texting. I figured she was sorting through alot of guys to find the right one. She’s a very pretty girl, she gives off an innocent girl next door vibe so i knew she must be getting alot of attention. I noticed her wearing more revealing clothes and doing her make up more often. She was taking more selfies and texting on her phone alot. I didn’t mind because she looked amazing and seemed to be horny much more often. She was more assertive and seemed alot more confident when we did have sex.
