Keep it simple: Pick the students up when their defenses are down and wear them out.

You've been assigned one of the side dormitories, a cozy room with six double beds and an adjoining shower room it shares with a similar room further down the hall, which you've made sure will not be in use.

Your team members are talented and eager, but they're still inexperienced, and though it chafes to admit it so are you. You figure your best bet is to avoid complicated plans with multiple failure points and just keep things simple: Pick the students up one by one at times when they'll be the most receptive, then introduce them into the session as they show up.

You figure you should start with E-19, since she's the one most likely to be non-compliant early on. If you need to be a bit forceful with her it's best if the others aren't there yet. Inexperienced femmes who haben't fully understood their position tend to get upset when futas get rough.

With that in mind, you've scheduled the session for a day when E Class has an evening workout. You take Lime with you and go to their shower room - having a couple of Class Managers show up there is nothing unusual, as fucking the girls in the showers rather than elsewhere reduces the need for cleanup.

This is the main shower room, a big tiled room with twenty shower heads along each wall and a line of fixed wooden benches along the middle where the girls can leave their clothes. There are no stalls of course, and while the security cameras are very discreet you know exactly where they're placed from when you were watching the feeds back when you were a Junior.

When you get there about half the showers are in use, with some girls towelling off while the last few stragglers arrive from workout, some of them having an obvious load of cum on them. Most of them seem happy enough, though they're a bit more subdued than usual after the hard workout Teacher Marble has no doubt put them through. Their assigned Class Managers are there as well, two of them fucking a girl each while the third stands outside the door and counts the girls in as they arrive.

As planned, Lime goes around the room chatting with the students and other Class Managers in her usual friendly way, while you identify E-19. As expected you find her in the back of the room, trying to avoid attention as usual, and she doesn't hear you approach over the chatter, splashing water, and sounds of fucking.
