(This story is a fantasy written from the point of view of The Top.)
I was able to lure a cocky swim team captain into my dungeon by telling him I wanted to do a photo shoot, and by appealing to his narcissism I was able to convince him into allowing me to tie him up while he was wearing nothing but his Speedo. I said there is nothing sexier than a man wearing a Speedo who gets tied up by a leatherman. I told him the dungeon was my workroom and it would be a perfect backdrop for this kind of a photo shoot, and he bought it all!
After he arrived and changed into his Speedo, I led him into the playroom/dungeon. I handed him a pair of leather cuffs to put on his ankles and told him it would add to the mystique of the shoot. Then I told him to sit on the floor under a steel frame lifting station, to bend over and wrap his arms underneath his calves, reaching around and grabbing the front of his ankles. While he was crouched over, the position appeared fairly benign, and he permitted me to bind his wrists tightly to his ankles with some rope (thus sealing his fate).
