simple premise: character wasn’t planning on having sex tonight or couple wasn’t planning on having someone join their tryst but they wind up having a threesome.

For example:

Woman is on a business trip and asks to stay at her sister’s apartment. Sister’s out so she says there’s no problem and her roommate should be out too so she’ll have the place to herself.

Well roommate and her boyfriend come back early and decide to fuck right on the couch. And MC comes out to check on the noise and after the confusion is cleared up, the couple is still horny and MC isn’t going to be able to get to sleep so she asks to join in.

2. Bisexual Guy doesn’t really do the club scene but he decides to get out there. To his shock, a woman comes right up to him and takes him onto the dance floor. Things get hot and heavy fast and before the’ve even shared names she’s telling him it’s time to go back to her hotel room.

Which is when a guy who looks almost exactly like MC show up and is very confused why his online hookup is dancing with another guy that looks like him. They cool off over some drinks and guy and his date says it’s too bad MC isn’t Bi or they’d be up for a threesome. MC then lets them know he is and they all go back to the hotel
 
I imagine a scenario reminescent of old italian porn. Introductory scene, with dialog but during the sex, little to none.

A new couple is moving into the apartment complex and our MC (M or F) meets them in a common space during. They are just a gorgeous couple. The MC has a couple of run-ns with them individually with lots of flirting and suggestive dialog.

That night the MC is looking off their balcony and across the courtyard into their neighbors room where they are having vigorous sex. They watch the entire scene and masturbate watching it.

After the couple finish they both sit up and look across and see her, with wide smiles. They left the curtains open on purpose. With that sexy little finger curl, they becon our MC to come over and join them.

What happens after is silent except for moans and the sounds of sex. This would be perfect for a bisexual man or woman.
 
There's always the classic "Three people wake up in bed together, and none of them really remember what happened after they all got drunk/high." But the sensations in their genitals indicate they all did have some kind of sexual release. So do the stains on the sheets. And the scratch marks on two of their backs.

I really like this! The idea of someone being caught spying and then joining in is so hot.

There’s an idea I was mapping out that had that theme:

Woman with an awful boyfriend lies to her sister about breaking up with him so she can get some money from her to get him out of jail. Sis is ecstatic and tells her to just go to her apartment and get it out of her petty cash. Roommate might be there but she’ll let her know she’s stopping by

Woman feels awful but when she arrives she’s in for a surprise as roommate and her boyfriend are making hot passionate love, the type she’s never had with her boyfriend she gets caught watching and she gets asked to join in. She’s reluctant at first, thinking their compliments are pity or outright lies but as she sees the way they look at her she realizes they genuinely find her stunning.

After a passionate night, sis’s roommate makes her block her boyfriend and MC is able to move on with her life

Figured I’d make it sis’s roommate to add to the spontaneity. They barely have an existing relationship but roomie and her boyfriend are just the right positive kinky people for her to run into
 
How about a woman in her early 40's, she always took pride in her body and is in good shape, especially for her age. Yet she never found 'the one' and is still single and a bit lonely. She decides to go to a club, just to see if she is still wanted by the men. To her surprise there is a guy interested, a younger guy in his mid 20's, he is there with a friend who is hitting on the younger women. She dances with him, they kiss and grope each other, she loves the fact that a handsome young guy is interested in her.

However at the end of the night when she invites him back to her place, he turns her down. He is there with his buddy and they agreed to not let the other travel back alone and since his friend didn't get lucky that night, he can't go with her. So in a horny move to get the guy to go with her, she tells him to just bring his buddy along to her house... Thinking the buddy could crash on her couch or something, things however don't go that way...
 
Here's an option: Impromptu Threesome, where a couple are fucking, likely at a Bathhouse, swingers den, or other area where the rules are akin to "Anyone is free to join in," and they inevitably have an unexpected participant in the form of someone intruding. Picture it: A guy has a girl riding cowgirl, but they intended to be secluded in their room and forgot to close the door (In a bathhouse, an open door is an invitation to watch or join in). A random guy walks by, sees that the door is open, and unceremoniously assumes they're interested and puts his dick in her asshole. She's shocked, but once she feels his cock slide inside her and starts having an orgasm, she decides to let him continue, and they fuck her til they have a combined creampie.

On the second idea, I once was in a bar where some group was ordering drinks. I caught a name and hit "fuck it," and repeated it as if I knew her and gave the extra drink I had in my hand. My friends had been refilling my drink and when it wasn't fast enough they filled another glass.

She took the drink in a heartbeat, and we got to talking. There were some weird moments in the chat which ai glossed over, like how she liked this hairstyle. She was fun and talkative as if we knew each other for years. When we were leaving a friend of mine, and apparently her friend as well, was motioning "2" all the time as we left.

Everything was great in the bedroom until she called my twin's name. It all clicked then, and a moment later it clicked with her as I slowed down in my surprise. She hung out with my brother quite often, and my open interest in her had taken her off guard. From my side it felt really natural as it didn't feel like chatting up a stranger, so it was easy to push the sexual boundaries.

We had a good laugh, we took a moment to get back into it, and after some minutes we could continue.
