The next day was sunny and hot. The four of us took a long mountain bike ride through the surrounding hills. Mountain biking does not lend itself to conversations thus we did not discuss what happened the night before.
On the way back to the motel, we spotted a thrift store. Jill insisted we stop in. She convinced Emma to go in with her. Jill stated that they each needed a costume for their dance routine the next night. I could not believe that the wives were going to go through with it.
Carl and I walked down to a grocery store to pick up a few things while the women shopped for clothes.
"Ben, do you really think they will enter the armature stripping contest?" Carl asked me.
"It looks that way, but I suspect they'll chicken out at the last minute."
Shortly after we returned to the car, Jill and Emma emerged from the store, each with a bag. When pressed for details on their costumes, they giggled and said we would have to wait until the next night.
Upon returning to the motel, we booked the hot tub room for 9pm. After each showering, and relaxing a bit, we went out to dinner downtown. It was a fun evening and we got back to our room a little before hot tub reservation.
Jill and I quickly changed into our swimsuits. Emma was taking her time. Carl announced that he would not be joining us in the tub, preferring to watch tv.
My wife and I made our way to the main building. We entered the hot tub room, and were surprised to find four people in it—three women and a man. All were standing outside of the tub, drying off. All four were naked! They seemed unabashed. Two of the women seemed older, maybe fifty, while the other seemed younger, and the man was younger too.
I tried to leave the room quickly so as not to embarrass them and give them some privacy, but they insisted not to bother. They were on the way out. Jill and I stood quietly by the door until one of the older women, still naked, asked us about our day. We explained that we had gone mountain biking.
In turn, she told us about their day which involved hiking. The longer we stood there, the longer I was staring at their naked bodies. The older women were not bad. The one doing the talking had huge, flabby tits. The other was a little plump, but looked good. I was surprised to see she had shave off all of her pubes and when she turned around, she had a tramp stamp. The younger woman was rather plain with wide hips and medium-size tits. The guy was the best looking of all. He wasn't ripped, but he was lean and in good shape. He also had shaved off his pubes which made his cock look big. I glanced at his crotch a few times, and each time I looked back it, his cock grew bigger and more erect. After a few minutes of chit-chat, he caught my eye and smiled.
They said that they were visiting from Colorado. They came down twice a year. The conversation changed to our dinners out. We mentioned that last night we had eaten at the restaurant a few doors down. Our four, naked friends said they love that place.
The other, older lady asked with a big smile, "Did you stop in the Spice Factory?"
My half-hard cock surged to its full length. I was making a big tent in my swimsuit.
Jill said, "That place is pretty exciting."
"Margaret and I love to check out movies in the booths," the first older woman said.
I was stunned that she would say this to people she just met. Jill countered, "Aren't they great? Did you guys see that movie, 'Eat the Seed'?"
The four of them looked at each other and grinned. Margaret said, "See it? Honey, Joyce and I were part of the study."
"Really?" I inquired with disbelief.
"Yup. Both of us participated in the three-times-a-day oral study."
My mind was racing and my dick was very hard. "How did you find out about the study? How did it work?" I asked.
Joyce explained, "Oh, it is pretty famous. The group in charge has been in the news for years. At first, it was very controversial, but now it is just thought of as a medical clinic. They advertise in the papers all the time for volunteers. They put you through some vigorous health tests. The clinic only takes about a third of those who apply. It turns out that most men are too out of shape to produce a lot of seed."
"Wow," Jill replied. "Was it scary? Or fun?"
"A little of both," Margaret said. "The toughest part for me was watching tapes of me participating in the study. That sort of thing scares off a lot of people. Joyce and I thought the whole thing was a blast. We recommend it all the time. I've convinced most of my reading group to sign up as volunteer for a study."
"Were you in the movie?" I asked.
