The Summer I fucked my GF’s 18-year-old cousin – PART 2 [MF], [cheating], [anal]

I was surprised by the amount of attention [part 1](https://www.reddit.com/r/sexstories/comments/go44ek/the_summer_i_fucked_my_gfs_18yearold_cousin/) of the story picked up. I apologize for taking so long to write these out, I currently work countless hours in front of a screen and I avoid screen time whenever possible. This story will be a bit shorter, there was a lot that happened that summer so I will focus on the main parts.

The next morning, I woke up feeling so horny. I wanted to sneak into Maria’s room and “play” with her but I was just fantasizing. My gf was still asleep so I went to the bathroom to rub one out. After my mind was clear, I realized that I had to make sure this stayed a secret. I knew that is my GF found out about Maria, that would cause a lot of problems for me and their family.

I went downstairs to watch some tv and eat a bowl of cereal. As I am eating on the couch, I hear someone walking down the steps, I knew it was Maria due to the sound of her light steps. She leans over behind me and gives me a hug which surprised me (I almost poured my cereal over). I told her to stop with a serious look on my face. She looked back like she did something bad.

The Summer I fucked my GF’s 18-year-old cousin [cheating] [MF] [Anal]

I was probably a senior in college. I was close to graduating and the homework at the time took over my life. If I was not in class, I was either at work or doing homework. I was living with my girlfriend at the time. We stayed at a whole house with multiple rooms by ourselves. The house belonged to her family but they stayed out in the suburbs and would normally rent out this house but my GF needed a place to stay while she was looking for something more permanent. I was technically not fully living there, but the house was between work and school so I always crashed and my GF didn’t mind it. She actually just pushed me to move my stuff in.

Several months in, my gf comes to me and asked me if it was okay if her cousin moved in with us for a bit. Her cousin was having issues at home with her parents and she just needed a place to stay before she moved to college in the Fall. I was fine with it, but I also couldn’t argue against it, it was not my house and I am also a very caring and helpful person. My only concern was that it was May, so that would be about 3 to 4 months that she would stay with us.

I[M] need advice on what happens afterwards

Hi, my gf and I have been curious about trying new things like having another guy join us or cuckolding. Although it is an exciting fantasy for both of us, we barely follow through. sometimes we bring it up outside of intimate times but nothing concrete. We both know if the situation is right (find someone we trust, get a little drunk) then it will happen.

My only concern is how will it affect our relationship? How was it after your experience with a third person(or multiple) in bed. I know that all relationships are different. But I want to know what we are walking into before we cross that line.

If you can message me about your experience and how things were afterwards, that would be great.
