You suggest the 3 of you explore the hotel

You are getting hard watching your friend's legs rub on Donny. Trying to break things up, you ask if anyone is thirsty.

"I'll have a pomegranate martini," Katy says playfully looking at you.

"Hey Gretchen, how about you, Donny and I go explore the hotel a bit?" you suggest.

You all agree and before long the three of you find an abandoned coat room. There is a small love seat against the wall and Donny leads Katy over to it and as she sits, you are shocked to watch her pull up her dress, rolling on her side. It doesn't take any time at all for Donny to have his cock out and shoved up Katy's anus. Donny starts to fuck her ass slowly, her neatly trimmed pussy having been skipped over is fully exposed.

Katy moans loudly as Donny plows her with his thick cock. Minutes later he explodes in her, cum dripping from her anus.

That's it, you can't take it anymore. You pull out your cock, roll your friend on her back and fuck her sweet pussy.

You explode into her.
