"Wake up, sleepy-head!" Aunt Jennifer said, while pulling the bedsheet from my bed, fully exposing my morning wood. Over the last couple of days I had gotten used to being this exposed to her. Nevertheless, it was feeding my horniness to have her look at my hard-on. "Get dressed; Judy will be here in half an hour. We're going shopping!"
"Judy?"
"Judy is my neighbors' daughter. You'll like her. She's about your age I guess."
"Does she know about our... arrangement? I mean, the rules?" I asked
"Well, she hasn't heard it from me. Although I don't think she's the type to be offended."
After breakfast Judy arrived and was introduced to me. I stuck out my hand to greet her but she ignored that by grabbing my shoulders and kissing me on the cheek. Judy was a vibrant and attractive girl with high energy and a happy-go-lucky demeanor. I liked her immediately.
We got into Aunt Jennifer's car and drove to the shopping center, about a 30 minute drive. I volunteered to drive, because I suspected that the ladies would like to plan their shopping spree. It turned out I was right; they were enthusiastically discussing the different stores, the outfits they needed, for sale items... Very stereotypical, but I did not mind. I was happy to tag along and secretly hoped to sneak a peek or two in the fitting rooms.
Judy tried on a short skirt. When she showed it to us, I did not dare to mention the fact that her underwear was peeing out on top. Aunt Jennifer was not so inhibited; "Stripes and dots don't match, dear!" Judy laughed and adjusted the waistband.
Both Judy and Aunt Jennifer were apparently looking for new bikinis and had collected a stack which they handed to me to hold while changing. This was almost too enjoyable for me: two beautiful women were taking turns showing sexy poses and walks that would not look out of place on the catwalk. Aunt Jennifer seemed to use her slightly more rounded features to compete with Judy's younger and very fit body, walking with swinging hips and even squeezing her breasts together.
"You need one with a bigger bottom, or we need to shop for razors too!" said Judy, taking revenge for Aunt Jennifer's tease earlier and she pointed to the tuft of pubic hair sticking out of the top of her bikini bottom. I had seen this before on her over the last few days, and found it sexy on her. I found myself staring and it was clearly too obvious: both ladies were looking at me and laughed. "Little perv." whispered Judy with a smile.
"Don't you need something?" Aunt Jennifer asked me.
"No, I'm not really into wearing bikinis." I answered jokingly, and also remembered that I was supposed to be naked around the pool, so swimwear was not needed.
Judy tried on a summer dress and showed it to us, slowly turning around to show it from all sides. We both confirmed it looked very good on her. Aunt Jennifer walked away for a moment to hang back some of the clothes they tried on. Judy started to walk back to the changing room, and made a fast twirl which swung up the dress showing me that she was not wearing underwear! She quickly threw a smile at me, before disappearing behind the curtain.
We had some lunch together and with several bags of shopping under their arms we went back to the car. I was about to drive the same route back when Aunt Jennifer stopped me: "we're not going home yet, way too early. Go left here."
Following her directions, I finally pulled up at a parking lot for a beach. We got out and Aunt Jennifer handed me some bags to carry from the back of the car. "The beach?" I asked, "I did not bring any swimwear!" I protested as we walked to the beach.
"That's on you, I even asked if you needed anything, and you said no!"
"Don't worry, we'll walk a little farther; there's a clothing-optional section there" Judy offered. We walked on.
She was right, there was a nice, and more or less secluded cove. At the edge there were some trees that provided shade. We picked a spot near the edge and settled. Aunt Jennifer and Judy were changing into their new bikinis under a large beach towel and I stripped down to my boxer shorts. "That has to come off too!" Aunt Jennifer instructed me.
"But the two of you are wearing swimwear!" I protested.
"Yes, swimwear, but you did not bring any, did you, now go on, take it off." I looked around and saw that there weren't a lot of people at the beach. Nearest to us, about ten yards away, a young woman in a bikini was reading a book. A bit farther, a nude couple who I guess were in their thirties were eating some fruit. There were also a few people going for a swim. Nobody was paying attention to us. I also realized that Judy had just flashed her pussy at me in the clothing store. That put my mind a little more at ease and I pulled down my boxers, stepped out of them and laid down on my towel.
After lying in the sun for a while, I felt the need to pee, so I stood up and excused myself: "I have to take a leak." and started to make my way to the trees to find a place to relieve myself.
"It's so cool that guys can pee standing up, I'm so jealous!" Judy remarked while jumping up from her towel. "Wait, can I... I mean I want to know what it's like to aim. Can I hold it?" She looked at me with begging eyes and jumping up and down enthusiastically. There was no way I could deny her.
With Judy in my footsteps I picked a tree that gave some cover from people that might see us from the beach and took position. "No, this way." Judy corrected me by grabbing my shoulders and turning me away from the tree so that I was facing the sand. One arm still on my shoulder, she grabbed my penis in her other hand, pressing her boobs into my back. "Go ahead."
I started to pee and Judy let out an enthusiastic "Yeah!" It took her a few seconds to get the hang of aiming the stream. Then she got creative and wrote her name in the sand in cursive letters. It was an odd experience to pee hands-free. Coincidentally I was finished when Judy ended writing the final letter of her name.
"How do you get the last drops out?" She asked. "Do I just shake it?"
"Then those drops will fly everywhere. I sort of milk them out. With my fingers I squeeze from the base to the end".
