You can't believe Christmas is in a week. It got here so fast. And of course, on inevitability of the holidays is an extended family reunion. So, when your cousins messaged you asking for a place to stay recently, you didn't see the harm in it.

However, over the past couple days, there's been some... tension. You're not entirely sure why, but Annika & Christie have both been eyeing you strangely since they got here. Having never had roommates, you weren't really prepared to share a house with two other people, but it's deeper than just that. You can tell there's going to be a conversation soon, but you hadn't the faintest clue why.

That is, until today.

You wake up late one morning, somewhat groggy but well rested. You feel a bit unkempt, so you decide to start your day with a shower. You wander over to the bathroom, and seeing that the door is merely cracked, you open it and walk inside.

And you walk in on Annika and Christie having sex in the bathtub.

Annika is on top, grinding deeply into her sister, as she grabs Christie's head with both hands, pulling her into a deep kiss. You can hear Christie moaning deeply into her sister's mouth, tweaking her nipple with one hand whilst grabbing Annika's ass tightly with the other. After three full seconds of kissing, they finally pull apart to breathe.

And then they see you.

Christie immediately yelps, reaching to cover her breasts with one arm. Annika's eyes widen, her face shifting to an awkward grin as she leans back from Christie.

"Hey... So. Guess you're in the know, now."

Annika says, turning to lean on her side, resting on Christie's thigh.

"Yeah. Uh, we've been dating for a couple months now... We've been meaning to tell you, but we didn't really know how to say it."

Christie relaxes somewhat, putting her arm back down into the tub. She looks away as she begins to speak.

"W-we were meaning to tell you, because... um..."

"Christie thinks you're hot as fuck."

Annika intrudes, earning a death glare from Christie. She continues talking, barely giving it any mind.

"I mean, it's not for lack of reason, you are... A lot, all at once. So..."

She turns to Christie, who's once nervous expression has faded into a look of deep lust, staring you up and down like a predator. Annika turns back to you, and asks the fateful question.

"...Wanna join?"
