25M4F - My Slutty Friend Joins Us For A Threesome

We're dating, and unfortunately in a long distance relationship. You're coming to visit me for the weekend.

One of my closest friends at school here is a girl. Even though you try to play it cool for the most part, I can tell you get jealous of her sometimes since her and I hang out so much.

Well, also, my friend and I hooked up once...fucked for three days nonstop...but it was before you and I started dating, so that shouldn't matter, right? Her and I can be just friends...

Not that you can't admit that she's hot. You're bi and have dated girls in the past. Admittedly, do you miss being with women since we've started dating.

Physically, you're nearly opposites. You're tall, thin, beautifully pale, blonde, legs for miles, small perky breasts. She's shorter, with large breasts that hang down and large pink aureolas, and a constantly wet pussy tucked into her wide hips.

Right before you got here, I...um...hooked up with her again accidentally sort of...but obviously you don't know that.

As for the twist...strapons?...power dynamics?...condom/cum/jealousy play?...cuckquean?...

So...this weekend we get into a situation were we have a threesome...but how does it happen? Do we take ecstasy? Just hang out and drink? Run into her while we're out? Or something else?

Or turn the tables and ask for a threesome with another guy instead?
