One of the girls I dated years back was really athletic. She was into rock climbing and hikes up the mountain. I'm more of a stay a home and relax kind of guy, but her magical charms and super hot body convinced me to go with her on a lot of her outdoor ventures which I wouldn't normally do otherwise. She was fairly tall for a Chinese girl and not much for boobs or ass as she was so lean and slender. She had amazing endurance. She could fuck for hours, although sometimes she would fuck me so hard I was afraid she was going to break me in half!
Sometimes when she took me up on the mountain for a hike, she'd let me have some more unconventional fun. I was in nowhere near as good a shape as her, so I was often asking to stop and rest. When we did, I would take photos of the view and of her. As there was usually no one around at all, I often got her to take her undress down to her sports bra and underwear and pose like she was some outdoorsy model or something. She thought it was fun and sometimes would indulge me further by posing without the bra and underwear, just a hot girl running around the mountain in her shoes. I even got some great slow motion video shots of her jumping from one boulder to another in nothing but shoes.
Of course, all these antics would get me horny and I would end up fucking her up there with both of us looking out over those great views from the mountain as we came. Then back to the hike... which was the far less fun part for me.
After a couple months, she wanted to know more about my interests and fetishes and so I told her about my interest in sharing my girls with other guys. Initially she said that was crazy. But the more I told her about how I'd done it with other girls I think it started to seem less and less outlandish to her. While I had shared most of my girls with my close friends she was really not up for that. She did however have a close friend of her own.
It was a guy she'd known for many years. He was her main climbing buddy, every bit the outdoorsy type that she was, but they hadn't done much non-PG together. He'd seen her her underwear plenty of times as she changed clothes and seemed to really appreciate her body, but they had never pursued that interest. She worried that he might think it was weird getting involved in that way, but I assured her that any guy would love to do more with her, given the chance.
The next time the three of us went up on the mountain together, she tried testing the waters. It was a pretty hot day, so she was only wearing a sports bra and pants. A good ways up the trail, when there was clearly no one else around, she started complaining very forced and awkwardly about how hot it was, even though it wasn't unusually hot.
"Oh my god, it's so hot today." she kept saying over and over.
Then she suddenly just pulled her sports bra off and tucked it in her backpack. Her friend was rather stunned but smiled. She spun around a few times, I suppose letting the air cool her now bare chest and then continued on the hike. Her friend was pretty much locked in staring at her as we continued up the trail. After a while she pulled me aside and said she wasn't sure how to proceed. I laughed briefly and then waved her friend over. I directly asked him if he liked seeing her tits.
Confused but amused, he answered, "Of course!"
"Would you like to feel them?" I questioned further.
