Back with a story of that one time I ruined an open relationship [FFM]

Recently I got a follow request from a man I used to fuck, let's call him David. David and I met on Tinder, back when it was still decent toilet entertainment… or an app to find hook ups on, I guess. He had a pretty barebones profile and all of his pics were in black and white which was questionable, but I was drawn in by his very concise bio:

"My girlfriend wants to watch"

I swiped right and opened with, "here's my number. send me a photo of her"

Well, he sent it right away, and all of a sudden I wanted his girlfriend to watch too, because to say she was ethereally beautiful would be an understatement. I'm not bad myself, because how else could I get a man to just accept that as a conversation starter, but WOW. How on Earth David landed her, I still don't know. Think Liv Tyler as Arwen in LOTR. I needed her on such a deep spiritual level that my desire could've only been culled by tasting her straight from the source. But we'll get to that

Anyways, David and I set up a meeting, or a date if you could call it that. He asked that I show up 8pm sharp to their place, and that I wear "something nice". I opted for lingerie — shout out to my former sugar daddy — and a black dress that'd never failed me. Liz (let's call her that since I can't think), he told me, would be serving us dinner naked.

I would've died a happy woman right there.

Dinner was delicious. David explained their dynamic: The two of them had always had a dom-sub relationship but Liz had only recently come to him with her voyeuristic cuckquean confession. David was actually the one who was apprehensive about opening their relationship up like that. When he gave Liz permission to speak and she told me her feelings, I think I was giving her absolute heart eyes like in the cartoons. She then asked to hold my hand.

It was game over for me. Liz led me to the bedroom, with David following closely behind. He shut the door and said, without even looking at Liz, "Sit down"

She sat in the corner, watching as her boyfriend pushed me against the wall.

"Red good for you?" (We love consent) "Let's do it" (Enthusiastic consent!!)

David slid my dress off, revealing the soft lace that boosted my B-cups and curved against my ass, honed by hours in the gym. I heard Liz whimper. I drew in a sharp breath. In all of my excitement I'd forgotten I was at once both self conscious of my body and way too conscious of how crazy that situation was. I'd only had a handful of experiences with group sex let alone being watched by AND cucking a beautiful woman!

David kissed and licked me all over, and came to a slow right near my aching pussy. I felt his breath as I tried to subtly push myself onto his mouth. He kissed everywhere but my clit, dragging out the torture for both Liz and I. I looked over and saw that she was rubbing her thighs together. David gave me an excruciatingly long lick, letting the tip of his tongue linger on my extremely sensitive button.

Then he said "You can touch yourself now"

Liz cried out "Thank you sir" and moaned as soon as her fingers found the wetness that was now pooling under her. David knelt, fingering me while gently sucking on my clit. I'm sure I was practically dripping into his mouth as I watched Liz watch us. She came first, with a silent scream, her legs twitching but her fingers still moving. I fucking lost it.

"Please fuck me. Please, pleaseeee. I need it. I need you inside of me right now" "You wanna give my girlfriend a show?" "Yes sir" "Good girl" He finally looked at Liz, "You can prepare me"

Liz crawled over to undress David, and even put on the condom for him, rolling it on with her mouth. I looked down and smiled at her lazily. She beamed back at me, a vision of a woman who was having her wildest fantasy played out, then crawled back to the corner.

David threw me onto the bed. I spread my lips, making sure both of them could see how wet and ready I was. He slid into me hot and fast, average in size but above average in skill, pounding me with the distinct intensity only a man in a relationship with someone who isn't you can provide. In my throes of ecstasy I had an idea: "Fuck me doggy while we 69"

"You heard our guest, you get a reward"

Liz practically jumped into bed with us. I sucked her fingers, reveling in her cum as David and I got in position, only releasing them as she laid down under me. Fuck her pussy was so perfect. I wanted to dive in and never stop eating her out. Unfortunately I was also being rigorously fucked by her man while she explored my folds gently, so I couldn't focus on her at all. I was basically just moaning into her pussy. Logistically this was a nightmare, so David and I ended up just fucking me prone while Liz and I made out. I don't think my hands left her soft milky tits, even as David pulled out and ordered us both to kneel on the floor. We continued to kiss while David jerked himself faster and faster and my hands latched onto Liz's ass.

"Stick out your tongues"

We let our tongues twirl over his tip, and he came with a groan.

So things went on like that for a bit. Sometimes Liz would just watch, sometimes she'd join. I liked it better when she joined, and soon enough she was calling me to come over and hang out just the two of us. The trouble was, David started doing that too. THE EVEN BIGGER TROUBLE WAS, I was kind of an asshole and basically helped them cheat on each other… with me?

Shit hit the fan of course and I didn't see them much after Liz got a job in a different city. I still got a wedding invitation a year later though.
