Example:
My best friend asked me to join she and her husband for a threesome.

Example:
Let's have a threesome!

But I'm straight...

So am I.

Example:
me, my boyfriend, & this other girl from my skool had an intense threesome.

Example:
Cathrine screamed in happiness as she cracked into an orgasm, after Jack had cummed inside of her. Suddenly, the doorbell rang. Cathrine tried to get off the sofa in the living room to get it, but Jack didn't want to waste all the hard work he had done to get her into so much pleasure. After a good five-minute orgasm, they made their way to the door, with Cathrine still riding Jack. At the door was a beautiful blond woman called Jemmie. She stared seductively at the couple. Jack took his dick out of Cathrine's fuzzy vagina, but noticed that she was completely ignoring him. Jemmie leaped towards Cathrine, and they started making out. Jack decided to help by undressing Jemmie, caressing her giant breasts and hairless pussy. Once Jemmie was naked, they started to grind against eachother. Because they were so wet, strips of their juices were streaked across their thighs. The clapping of their pussies made them even wetter. Jack started to feel left out, so he parted the ladies and began to eat out Jemmie, while Cathrine gave him a blowjob. Suddenly, he couldn't hold it in any longer. He needed to have some of Jemmie's pussy. He shoved his dick in her vagina, while the two girls made out. he licked and caressed her breasts and nipples, nibbling them. he fingered Cathrine at the same time, which made them all have and orgasm at the same time. They fell asleep spooning, wet and shaking with happiness, then repeated in the early hours of the morning. It was the best threesome ever.

Example:
I was at my bfs house with one other friend. He wanted me to go to the bathroom w him, so I went and watched him take off all his clothes. I stared at his huge cock as he undressed me. I was getting so wet and he could tell. He started teasing by licking around my pussy. I couldn't take it anymore, so I shoved his face into my cunt. ooh it felt so good. He began licking my clit and I moaned a little too loud. My friend came up to see what we were doing, and when she did, she immediately tossed her clothes. We moved to his room and began. She stared at my huge jugs and started sucking and biting them as I fingered her. He stuck his dick into her pussy and started fucking her. I felt left out, so I grabbed his cock and stuck it in mine. She shoved my tongue deep into her pussy as she cummed all over me. I squeezed her tits until they became rock hard. We were all so horny, so we started watching porn to get ourselves to cum. We made a 69 train and licked all that cream off of each other. He then started sucking her boobs while titty-fucking mine. I scissored her hard while they made out. I then pinned him down and rode him as fast as I could while she gave him a rim job. Not only that, but I began sucking the life out of her tits while she choked on his massive dick. We fell asleep with his dick in my mouth, my fingers in her cunt, and his face buried in her huge racks. What a threesome. We decided to start doing this every week, and it became a part of our regular schedules.

"In this, I am dominate.The way we will start is that my wife, Cheryn, who'll eat out Marie, while I fuck my wife doggy style.Then, I will give Marie a palm job while Cheryn gives me a blow job."We all settle on this course, & we began.I watched my wife as she began to tonguefuck Marie for a sec.The sight of my wife fucking another woman made me cum, & I gave Marie a facial before turning to my wife.I fucked her doggy style for a minute until I commanded that we begin step2.Marie sat close to me and I began to feel her cunt.It was wet.I began to give her the best pj ever.My wife was giving me a bj.After that, I began to eat Marie out, & she ate my wife out.Cheryn came once or twice and I saw to it that Marie swallowed all of it.I began to fuck Marie in her pussy.Our cums exploded inside of her, and I made Cheryn lick it up afterward.

Example:
Billy Bob's only desire before he passed away, was to participate in a threesome.

Example:
1.) Larry, Harry and Mo were a famous threesome.
2.) "Hey, Tiffany, how about you and me and Delicia go over to my place for a threesome?"
3.) Now that Berrington has taken over the regional management, I think we're soon going to see an end to the Wallace-Kingwill-Mason threesome.
