Go find the Mellin twins

The Mellin twins are well-known throughout the academy, mostly as the subject of various rhymes of various levels of cleverness about how "the Mellin twins have twin pairs of melons." Nylan and Luphia Mellin, this set of gorgeous, well-muscled orc girls are identical in every way, from their oversized breasts, to their grass-green skin, to their chin-length black hair, to their winsome bubble butts. The only way to tell the difference is when Raider is in the room: Nylan is a Raider's Girl, and Luphia is in WAR.

You've had a lot of fun with these girls. Nylan has a transparent crush on Raider, and enjoys her occasional stripping, but only so long as she can pretend that she's actually Luphia. It's an interesting phenomenon to behold: She's far too embarrassed to be seen naked if everyone knows its her own body, but she's delighted to run screaming through the school, pretending to be mortified, if she maintains the possibility that it's actually her sister. And naturally, her sister is legitimately mortified to be seen naked.

When you catch up with the Mellin twins, they're in the middle of a workout down at the gym. Both are clad in matching workout gear, one spotting the other on a hefty bench press. They're enticingly sweaty, visible marks spreading out from their voluminous cleavage and their ass cracks.

Word has gotten around about Big Boobie Day, and a few students have discretely gathered in anticipation of the busty orc girls' stripping. Time to put on a show.
