They bring you to the Stocks

Still reeling from that intense experience, the girls doesn't afford you any time to recuperate. Minxy strides confidently ahead, leaving Big Lindsey to help you along. She doesn't seem to mind the task though, clearly enjoying the way you stumble around. Your body is still in that immediately post-orgasm state with legs that can barely hold you up, only further cemented by the intensity of said orgasm.
Being held down like that.. you try to deny it, but part of you found the helplessness incredibly arousing.

Big Lindsey however has snaked her arm around your waist and and put your arm over her wide shoulders. Compared to earlier her grip is almost tender, but to no surprise she turns out to be a solid rock to lean against. You walk down a corridor with one wall draped in old tapestry displaying outrageous scenes of men tied to everything from trees, to chairs, tables, beds and even anvils, water mills, actual animals and each other. Despite the lack of details, they are clearly all naked and beside each is a fully clad, widely smiling woman. What catches your eye though is the pattern of the frames. Individual strands that eventually all tie to together; by the third you pass you realize it's not just decoration - it's instructions. How to tie suitable knots for each occasion, a medieval BDSM guide! Honestly you'd almost find it fascinating if it wasn't so deeply disturbing. The cloth looks pretty old, but you never find if this is an actual medieval tapestry, because the girls herd you past the sign to quick to read anything.

Your impression of Minxy has always been a cheeky princess in a soft hourglass package, but as you step you step out into the Fixation Devices exhibition, she is positively bubbly. You quickly notice displays with a variety of manacles, from cast-iron to some really intricately shaped in floral patterns in what you assume to be silver. The next showcases what you recognize as penis cage, once more of different materials and times in general - you notice modern plastic next to wood. Brass, iron and a really nasty looking wiremesh that makes your cock twinge in sympathy for whoever left those tiny red stains. On you left you notice a pair of really old stocks. One seems fairly normal with three holes for head and hands, the other one has only one hole - this time way smaller. You grimace but luckily Minxy leads you right by it.
"Where are we going?" Big Lindsey asks, eyeing a strange sawhorse with a worryingly inspired expression.
"Dunno if I ever told you but my mom brought me here once.." Minxy tells, leading you around a corner towards the end of the exhibit. "Didn't really have much interest in boys at the time but then I saw this gorgeous machine. It was-.. Anyway I promised myself that I would bring a guy here one day to try it."

Just as she finishes her sentence she leads you around a partition and her eyes light up.
