[MF] I gave my best friend’s girlfriend the best sex of her life

It all started at one of my best friend’s college graduation party back in 2017. He had been dating this girl we knew from Elementary school for about 3 years at the time of the party. My friend (we’ll call him Chris) and I had been in the same friends group since Middle School so we were very close, but no one in the friend group knew his girlfriend really well. At his party, I made sure to include her in our friend group and even went as far as having all our friends add her on snapchat. She was very touchy feely with me, would laugh at everything I said at the party and this was the first time I had met her in person so I thought it was normal of her. Anyway, after the party ended she would snap me everyday, and it would be consistent, back to back snaps, all day, every day. I thought this was normal, I was trying to build a friendship with her, she would tell me she was going to marry my friend and I would always be supportive. She was a very attractive girl, long dark brown hair, a thing waist, about 5’6 and very busty. Whenever we would snap at night, she would always send me pictures that completely revealed her cleavage and I never said anything on because I credited it to her bustyness.
