I 18F and my friend 19F were hiking with my bf. We started out fine, none of us were horny until about half way up the trail. This was where I revealed to my friend that in my bag was a bunch of bondage gear and toys I wanted my bf to use on us while we were miles from the nearest city. It took a little convincing and a little demonstration on myself but she finally agreed to go through with it. We started light, we started by stripping naked and we both wore wrist cuffs, collars/leashes, and gags. Since there wasn't anyone around we decided to keep hiking without our clothes on. (yes we did have some bug spray and we did wear shoes.) eventually we reached a really nice waterfall along the trail. We start walking around exploring the waterfall when my bf really needed to use the restroom. He pulled us aside and made us shower in his urine. After that it turned us on even more where we started taking turns sucking his cock/cojones. after cumming very close to cumming we start debating who would take his cum first. Eventually he decides to spray it on both our faces. After that my boyfriend made me sit on a nearby rock with my hands and feet tied together. He tied me up with my legs spread and started fucking my friend like a wild animal. All I could do was watch helplessly. After what felt like an hour but it was more like 20 minutes my boyfriend decided he would be "nice and fuck me as well. But instead he gave my friend a strap on and a vibe to play with me while he forced me to deep throat him to my limit. He also lubed me up and covered my feet and legs with his cum just so he could make me walk back to the car naked and without shoes. He did this with my friend as well but he but a vibe in her; and put a 9" dildo in my ass. On that hike me and my friend orgasmed 8-10 times each. The hike back was mostly just filled with us teasing my bf and sucking his cock randomly.
