No, stay with the girls

You hesitate for long enough for Minxy to slink up up beside you, a predatory glint on her lips as she tugs you closer to the building by your belt. You chance passed, you send one last furtive glance back out the alley, only to see a police car driving by on the road. Maybe it was a good thing you didn't risk it.

"Got it!" Big Lindsey exclaims triumphantly. She opens the door to a darkened interior. Minxy confidently strides up the small set of stairs with you in tow. At this point you're just sheepishly following along. There's something quite alluring about the air of authority Minxy present, the certainty that you will do as she asks - and the promise of the rewards that might follow. In stark contrast, the way Big Lindsey easily womanhandled you earlier speaks of an experience you can't help find.. intriguing. Despite their age the girls have you playing completely by their tune.

"You think she's home?" Big Lindsey asks, glancing inside the doorway with a sudden hesitation. You furrow you brows, at this point you're basically breaking in, right?

"Nah, don't think so.." Minxy is quick to reply, "I think she's in that stupid book club my mum is running and they're meeting today. Prolly caught some fuckboy and they were going to toy with him all day." Her eyes dart to you and she smirks, "sounds appealing, slut? Some nasty old ladies reading pretentious "erotic" poetry while groping your junk?" She punctuates by dragging a nail along the fly of your jeans, the simple stimulation enough to send a quick jolt to your cock.
Both girls scoff but you're not given much time to consider whether it would be preferable before Big Lindsey finishes the thought for you: "Of course he'd rather have us! Come on!" Her arm snakes around your waist, a friendlier grip though no less steely, and both girls lead you into this strange museum.

The room smells dusty with a hint of some sort of wood treatment, though it's fairly quickly drowned out by the girls' perfume. Minxy once more grabs you by the junk, this time not as harshly, and leans into you. You feel the soft entirety of her curves barely hidden under the school uniform: her fat, full breasts, her warm, soft thighs and her breath tickles your neck when she whispers in your ear:

"Remember our deal. You try anything and you'll regret it." The threat is contrasted by her sweet smile and large brown eyes. You swallow and open your mouth to reply.

Only to get instantly silenced when Big Lindseys mouth conquers yours. She forces her tongue through your lips and greedily explores the inside of your mouth. She tastes like soda and cigarettes and her technique is 90% brute **** in a tongue kiss unlike any other you've experience before. The entire thing lasts maybe 5 seconds and after she finally lets go, she stares at your stunned face and says:

"And stay quiet. No matter what. We don't want to be found out." Her smirk turns dangerous and she wantonly gropes your ass before she adds, "else we might just have to gag you."

Caught as you are, between the inviting softness of Minxy and the freakish strength of Big Lindsey, still dazed by the kiss, you barely manage a nod, but it seems enough for the girls.

Your eyes are now accustomed to the darkness and you notice that you're standing in a simple lobby. This generally has the feel of a home museum. Just ahead there's a small counter with a small pile of tickets and a list of prices. Apparently both girls would've gotten a student discount if they had come within standard hours. Minxy has walked over to peek into a small, blue lockbox (paradoxically unlocked) but sighs when she finds it empty. A door beside the counter says "private".

On your right hand you notice two adjacent rooms, both have signs over the door openings. One cryptically reads "Boys as Toys", the other "A history of Milking Machines"
On your left it's the same, the signs this time are: ""The Stocks and other Fixation Devices", the other "The Wonders of Electricity"

Minxy turns to you with a bright smile, barely containing her giddyness by this point.

"Since you've been good so far, you can decide where we start."
