Unexpected visitors

“Jo!? Jack! Fancy seeing you guys here!” A vaguely familiar voice says.

You blink, the bullet clouding your thoughts ever so slightly and turn to see Mark and Kate. “Oh hi!” You say reluctantly, the situation suddenly complicated and requiring all your attention.

Mark used to be your best friend and had been dating Jo. Kate had also been your girlfriend. Six months ago you’d found Kate and Mark fucking in your bed - they were cheating on you and Jo - you’d cracked the shits. Ridiculously they two had offered a foursome with you and Jo but you’d been so incensed you’d stormed off. You’d called Jo and she’d been royally pissed. Somehow in all the post breakup confusion you’d ended up drowning your sorrows with Jo. This led to sex and… now you and Jo were a couple.

“What are you guys doing here?” Kate asked. She was now taller than you. Of African descent she was slim, small breasted and gorgeous.

“I’m teaching Jo to ski,” Jo says guardedly.

“Good for you,” Mark says. He is tall but not as tall as Jo - lean where Jo is muscular. Good looking though.

This is weird.
