“It feels really good in here. Makes me kinda horny,” Priscilla said, naked as a jay bird in the hot tub in back of the house our family rented for the week in Estes Park. Mom & Dad took our little brother and left us here while they went shopping, giving us a pass from the family outing because it was Priscilla’s birthday and they were getting party stuff. We decided to get naked in the hot tub, cuz duh. Is there a better way to be in a private hot tub? The water was a little warm for me, so I got out and she stayed in. We snuck some wine from the cabinet and were feeling light and sexy and fun while we talked and enjoyed being nude together under the Colorado sky in the bubbly, swirling water.
“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 consc
ious 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.
