Go back an hour

Bill stumbled back to her girlfriend, desperation finally overcoming her panic. She grabbed Heather's hand.

"You can go back, right?" she said. "Go back an hour. Same place, just... I can get dressed and get out before we even arrive, let alone her. She was here early, but she definitely can't be here back then."

"You're sure?" Heather said.

Bill nodded, biting her lip, praying Heather would start them moving before the door opened-

And then they were whirling through the void again. Somehow it was even more awe-inspiring than before. Winds that she could see, an endless, immaterial storm as terrifying as it was beautiful, and tiny glimpses of what was beyond-

She landed on the floor again, a little distance from Heather, face down. Despite herself she laughed, still riding high on the thrill.

"Ah!"

And then she heard a voice that definitely wasn't Heather's. Eyes wide, Bill scrambled up, far too aware of the fact she'd just pushed her ass up into the air.

Oh god, oh god-

She turned over, exposing her tits for a frantic second before she crossed an arm over them, pulling her legs up in the hopes of hiding her pussy. She stared up, to see her foster mother and a woman she'd never met before, about her age.

Bill squeaked. Fuck, of course this would happen.

Of all the days they'd landed, it had been one where her foster mum was apparently opting to rent out her room to other students. She'd gotten over Bill vanishing awfully faster.

"Bill!" her foster mum said. "How- what- why-"

At least seeing someone falling naked out of thin air apparently rendered her as speechless as Bill was from, well, falling naked out of thin air and being seen.

Bill glanced over her shoulder, glad to see Heather was at least in the room.

"Heather!" Bill called.

Oh god, they had to get out of there, it didn't matter where to.

"One second," Heather said, panting. "It's- a bit tiring."

Oh god, she was a permanently naked passenger aboard a time machine that got worn out. Bill shifted, clutching her legs against her chest in panic as the two other women took her in.

"Now wait a moment," Bill's foster mother said, as Heather started to move. "No! Don't you go near her! What are you-"

She tried to get in the way, stopping Heather from crossing the room and sparing Bill from this humiliation. Bill swallowed, then braced herself, and **** herself to her feet.

Squealing as she flashed her ass to the woman being shown around, she reached out with one hand, baring her pussy for a moment in her haste to touch Heather-

"Please!" Bill shouted.

And, thankfully, they quickly left that humiliating scene.
