“It’s your birthday, Pris. You should be able to do whatever you want.” I said, noticing how she was letting the jets blow between her legs. I knew how she felt. What girl didn’t linger in front of a water jet in a pool when she was little, enjoying the way the pressure felt on her vagina. I’d done it many times. She was the birthday girl. Why shouldn’t she get to enjoy some pleasure down there while we were in this beautiful place? I wasn’t going to stop her from it.
“You wouldn’t mind? It wouldn’t weird you out?”
“Kinda hot to tell the truth. If you don’t mind me watching.”
“No,” she smiled. “I don’t mind.” I’ve seen my sister naked a lot, and never had sexual feelings toward her, besides a little experimentation a few times I guess. And some curiosity. But, watching her spread her legs and open her body up to the jets, seeing the effect it had play out on her face was really erotic. I felt a thumping in my nether regions that made me cross my legs.
“Oh my god, are you turned on?” She asked, seeing right through me!
“Maybe,” I laughed, dropping my head to my knees in embarrassment. I wanted to cover up and hide all of a sudden.
“Then you should let me watch too,” she said. Okay, we are doing this! I let my towel drop to the floor and my legs fall open, exploring my trimmed pubic hair with my fingers while she positioned herself in front of the water flow and let her eyes drift closed. I was already wet. My fingers slid easily over the sensitive, slippery skin around my pussy. I gave my clit a tickle as she swirled her hips around, letting the water caress her all over. She giggled at me, a little self conscious that I was watching her with horny interest.
“Are you going to make yourself cum?” She asked me.
“I will if you will,” I answered, tickling downward to my butthole and back up. Her eyes followed the path of my fingers. She leaned back, pushing her crotch forward towards the front edge of the hot tub where the jets were, rotating slowly. I imagined the bubbles massaging her labia, their fleshy petals flittering in the current. “How does it feel?” I asked.
