Pretend you think it was a joke

This could end up being a lot of emotional baggage to unpack. You have to react quickly before things become too awkward, so you burst out laughing.

“Ah hahaha! Good one! You had me going there!” you tell Sabrina.

Emma darts her eyes to Sabrina to see if she is kidding as well.

“Oh, we were all over each other, you should have seen it,” Sabrina continues on, dead serious. Emma looks like a kettle ready to start piping hot steam. “Emma wore my strap-on and really shoved it up my pussy good!”

“Uh huh…” you respond in a condescending tone, still grinning

“She rode me like a horse,” Sabrina continues with resolute sincerity.

“Oh yeah?” Emma chimes in. “Well, after that, I had HER put on the strap-on and then she really gave it to me!”

Since you’re not buying the story in the first place, things have converted into a bragging competition between the sisters.

“She had me climbing on the walls with her sensual thrusts!” Emma goes on. “That big long dick, shoved in and out of my pussy… It’s almost like she should have been born with one!”

Sabrina sneers at her sister. “Well, the way you were begging for it, I had to give it to you, but good! You’re an insatiable slut, that’s all!”

“I don’t know, I’ve never had a cock in me quite like yours, sis! Your thrusts were so strong and forceful!” Emma goads.

“Oh really?” you interject, doing your best to feign indifference.

“Oh yeah!” Emma replies, turning to you. “I was like a bitch in heat, begging for her to stuff me with that long, thick cock!” She plays up her story, starting to get into her boasts. Her body starts to undulate, recollecting her moment with Sabrina. “I came hard! Twice! From her shoving that python of a shlong down my gaping pussy! I must have woken up the neighbors from my moans. My uvula was practically singing!”

“From the way you color your words, you should get a side job as a writer,” you praise, lifting your glass and taking a sip of your drink. You try to discreetly adjust yourself in your seat. Your pants are getting increasingly tighter as the girls get more and more detailed with their sexcapade.

“Well, Emma made me cum hard too!” Sabrina pointed out more succinctly. “Our… bodies rubbing up against one another, heavy breathing… the sweat… the scent of our juices…”

“So, was it good for you?” you ask with a bemused smirk. Listening to Sabrina and Emma openly describe their torrid affair is just as arousing as watching it happen live.

“Best sex I’ve ever had!” Sabrina answers without hesitation. You raise an eyebrow. She could very well be telling you the truth. You’re still not clear how much experience Sabrina has with sex aside from the times you’ve witnessed personally. You start to wonder if you’ve personally seen every single sexual encounter in Sabrina’s life.

You lean in and look Sabrina in the eyes, then Emma. “The way you two describe it…” you say slowly as you raise an eyebrow. “Did you two really…?”

Emma’s cheeks go red. Sabrina eyes her while biting her lip. Neither is eager to admit it’s true anymore. It’s a game of chicken between them to see who will admit to it first. AFter a long pause, Emma can’t take the suspense any longer.

“OK, you got us! We were just kidding about all that!” Emma admits with nervous giggles. It appears that she’s not as open to this new side of her as she had claimed.

“Well, I knew it had to be a lie if your sister would give you such high praise,” you chuckle.

Emma looks over at Sabrina with a faint smile, then turns back to you and says, “Yep, all a lie.”

“Well, I need to use the restroom,” Sabrina says. She looks relieved. Either from everyone agreeing to pretend the story is made up, or from having laid it all out on the table in the first place. She gets up and leaves you alone with Emma.

Emma looks at you nervously now. “Hey, you’re not weirded out about us making up that we slept together, are you?”

“Nah, I asked for something wild and you delivered,” you reply.

“That’s good, because I just wanted to impress you,” she smiles impishly.

“Color me impressed.”

“Impressed enough that you’d want to go out sometime?” she asks, running her finger over the lip of her glass.
