My boyfriend wanted an open relationship so he could sleep around. Now I let my best friend fuck my brains out almost every day.

My boyfriend really wanted an open relationship. He’s pretty good-looking and kept saying he doesn’t handle monogamy very well and wants more sex and to sleep with other women.

I thought about it for a while and was skeptical at first. But our sex life is really pretty mediocre, so I thought a little new excitement would do us good, and besides, I had a bit of a crush on a good friend and wanted to pursue it.

Six months ago, we took the plunge and opened up our relationship.

I told my best friend about it on Friday of this week and flirted with him a little, and he immediately understood what I wanted. Shortly after, I was kneeling naked in front of him and giving him a blowjob. He pressed my head tightly against him, and since his cock is really thick and long, I could barely breathe, which turned me on so much.

Then he fucked me really hard doggy-style. Before that night, I was on Team “Size Doesn’t Matter,” but he changed my mind on that. It was so hard and intense, and I felt so much more because his cock was so thick and hard and penetrated so deeply.

He has a natural dominance that I’ve never experienced with any other man, and that really turns me on—plus, he has so much stamina. Three or four rounds in one night, each time easily 20 minutes of good, hard sex. I’d never experienced anything like that before.

The next day, I was in pain when I walked, and in the bathroom I saw that my entire neck and upper body were covered in hickies, scratches, and a bite mark, and my ass was still completely red from the hard spanking.

My boyfriend picked me up and looked pretty shocked at how I looked. But it seemed to turn him on too, because during the drive I saw a bulge in his pants.

At home, he immediately ripped my pants off and told me he was going to fuck me so hard that I’d forget about the other guy right away. I thought about turning him down since I was already so sore, but I kind of found it hot. Besides, he comes pretty quickly anyway when he’s that turned on.

He thrust his cock into me, and I was shocked by how stark the contrast was—how small he felt. In that moment, I knew I wouldn’t be monogamous with him ever again.

He gave it his all to fuck me really well, and it was hot, but nothing compared to the night before with my best friend. After about two minutes, he came, and we cuddled.

The following week, I had sex with three different guys right away, including my best friend. I was basically having sex with different men every day, while my boyfriend kept getting rejected by women and just waited at home, always picking me up like a good boy.

Six months have passed since then, and the dynamic between my boyfriend and me has completely changed. Should I tell you more about it?
