She laughed and nodded. "I see what you mean. I guess I won't be needing these." She smiled and took off her labcoat, her shirt, skirt, bra then her panties.
"This is an airlock." She said, letting her into the room. "You'll be able to hear me through the headpiece on your mask." She shut the door and it clamped with a sucking sound, the room begining to flood.
She looked back at the woman and gave a comforting smile. She gave a thumbs up before she closed the door. She took a deep breath and watched the room fill with water.
once full another door opened, letting her into a large tank, with many rocks on the sandy floor.
A shadow swam overhead, a pointy nosed beast, 12 feet long, like a shark with finned legs.
She swam in and took a deep breath. She swimmmed/walked on the sandy floor. She saw the shadow and looked up. She pushed herself off the floor, and the young woman kept her body near the top of the tank.
He swam along under her, belly to belly, positioned so the slit was pressed to her pussy. It felt almost like a hot, slick tongue pushing into her, his cock wriggling into her of it's own accord.
She smiled and watched him position himself. She took a moment to study it. It was beautiful. She felt something push into her. It felt strange. She shut her eyes and let out a soft moan.
