spe·lunk·er: n. One who explores caves chiefly as a hobby; a caver. Well, these three spelunkers turn into spunkers after their caving trip, and both guys explore this blonde cutie's pink little cavern while sharing their own purple headed stalagmites with each other! It's a hot outdoor scene where every crack, crevice, and conical formation is explored, and by the end, both guy and girl is glazed in mineral-rich fluid!
