My gf(22f) and I(21m) have been talking about swinging and sharing for a long time now but we wanted to keep our life private and the idea of it getting out did scare us a bit. My gf doesn't seem the sexually wild person she is when you look at her. She usually dresses pretty conservatively and didn't have a lot of exes either. But we both always found the idea of swinging very arousing.

One night my gf and I were hanging out with a friend of mine(26m) and we were getting high. My friend has his own place and is a bit of an introvert. He isn't really my gf's type at all. And his house is always a mess which also kinda puts of my gf but he always has weed and he is a chill dude so we do hangout with him. This particular night my gf was being a bit more touchy than usual. She was kissing me and was on my lap and I wouldn't say I didn't enjoy it but I didn't want to make my friend uncomfortable so I tried pushing her away. My friend seeing this laughed and asked if he should give us some space. My gf then said that she didn't mind if he watched and then asked if I did. This caught me completely off guard. My friend was equally confused but he played into it and said he would love to watch and I smiled to it to. I teased her to put on a show. I thought she would stop after a while but she didnt. Our clothes were on the floor and I thought surely now she would want to stop but no, she was only getting more excited and I was too. I invited my friend to join in after asking my gf if she wanted it. After that the night was a bit of a manic blur. My gf has a huge kink of being used and treated like a ragdoll at times. We are usually more softer when we have sex alone but when I shared her, it felt like all three of us were just consumed by lust.

We meet up few times a week after that day and now it feels like a casual occurence. I love every moment of it because it feels like both me and my gf are different people during the threesome.
