So it was just 30+ years. The threesome was me my gf and another girl.

I had never thought about a threesome. One time at college my gf was talking to her friend about sexual stuff, comparing bfs cock sizes, talking about how they masturbated. Where they liked getting cummed on. Then they started talking about a threesome. And to what my gf (at that time) said was they bunked the rest of the day of went to a coffee shop and started talking about if they should have a threesome. Her friend was close to breaking up with her bf so my gf suggested me.

I got a text just after leaving work saying get your family out the house I have a surprise. By the best luck in the world my family had left to spend the night at another family members house.

I got home and my gf was laying on the living room floor in her sexiest our of underwear. I started to undress, later down next to her and started kissing, she paused and said

"Do you want your surprise"

And in walks her friend in nothing but her underwear. She sits intop of me and starts kissing me. Then my gf and her started kissing. Her friend moved over and sat on my gf.

I unhooked her friends bra and started to play with her boob's and kissed her neck. My gf slide of her friends underwear and started to play with her pussy. I stood up and her friend started to blow me. After a little while my gf got on her knees and I was recieving a double blow job.

The girls got fully undressed and started to 69 each other. My gf was on top. I got behind her and started to fuck my gf from behind as her friend continued to lick my gf. I alternated between fucking my gf and fucking her friends mouth.

After a little while my gf cummed. She needed a breather so I played down next to her and her friend sucked me while we kissed. She whispered to me

"Can you make my friend cum?"

I told her friend to lay down and I fingered her until she cummed. And squirted a little.

I got on my back and my gf got ontop she rode me while her friend sucked my balls and licked her ass. I cummed inside my gf and after my gf got of me her friend cleaned the cum of my cock.

It was just a one time thing and our relationship didn't change it got better at the time. And her friend just remained her friend

There was a few times shortly after when I'd see my gf and her friend at college and they would giggle and save to me. One time both jokingly pussy licking motion with her hands. It was a great experience and there was no regrets on any sides
