Watching my best friend [m30] fuck the love [f33] of my life, Part 1 [cuckold’s perspective]

I am writing during my lunch time. I try to include as much details as I can. This was originally posted in another subreddit, but it is taken down due to "Low Effort Post". Also in that subreddit, I mentioned that this is my first cuckolding experience, something i have been planning for over a year. Finally I have my gf agreeing to fucking my best friend while I watch and film. My gf agrees to wear black stockings, to be tied up to the mattress, and have my best friend do whatever he wants. We even give him the option to cum inside of her if he wants. Anyway, here is part 1 of what happened. If you guys want part 2, let me know, it will encourage me to write the rest of the story over the weekend.

I [m34] picked up my gf, Iris, around 8pm yesterday. When she got to my place, she went to the bathroom and got all dressed up for the occasion. She looked amazing in that vaguely see-through shirt and black stockings! I got immediately turned on seeing her like that. My hand reached out and touched her crotch, realizing she wasn't wearing any underwear, and she was soaking wet. Right then, I started kissing her neck, sucked on her breast, and bent her over and fucked her right in the hallway. After 10 min, I was about to cum, but I managed to hold it in, didn't even finish. I looked at her passionately, seeing the love of my life and in a hour she will be fucking someone else.

After that, we chilled on the mattress I'd set up in the basement, just waiting for my buddy Jake to show up. Lying with her, I could still feel how wet she was, her pussy practically begging for more, so, of course, I went for it again, fucking her hungry wet pussy. I still manage to hold it back again, but it is getting increasingly harder!

Finally, about 30 min later Jake showed up. We got straight to setting up the bondage gear on the mattress. I put the cuffs on her wrists (you can look up amazon mattress bondage gear to get an idea what they are like). We started off casually, I had Jake and Iris sitting on a 2 seater sofa. I sat across them. Jake started teasing Iris, kissing her neck, touching her legs, touching her breast under her shirt. Watching my gf closing her eyes, enjoying the moment. At this point, I proposed to take it to the bed. I took Iris to the bed and cuffed her wrists to the mattress. After tying her, I unbuttoned her shirt to expose her breast, so Jake can have full access to them when he fucks her. I spread Iris’ legs open, kissed her legs, then her lips, and told her that Jake will be taking over and fucking her now. Turning around, I saw Jake already stripped naked, condom is already on. I moved out of the way, sat on the sofa, with camera on my hand, seeing Iris’s hands cuffed to the mattress, arms spread out, pussy and breast exposed. Jake kneeled between Iris’ legs. Iris laid on the mattress motionless, looked at me, as Jake pushed his penis inside her.
