You find out after the ritual

You and Alena both retrieve your clothes and get dressed after the sex ritual. Alena begins cleaning up her supplies and placing them into her backpack. Her "spell book" and lights seem to have dimmed now that the ritual was over.

"So, what exactly was that supposed to do?" You ask.

Alena gives you a strange smile. "All in good time, my love."

The door to the classroom bangs open and you turn to see Sasha closing the door behind her. To your shock, she is in her underwear and panting heavily. Her bra and panties seem to disintegrating before your eyes, as if they were dissolving in some invisible liquid. Sasha mutters under her breath, "Oh, thank God! I made it!"

She turns around and faces you, giving you a small glimpse of her naked breasts and shaved pussy, before screaming in fear and covering herself. You can't help but notice how her attractiveness is heightened without her glasses. "What are you two doing in here?! School ended an hour ago!"

"Whatever might you be doing here?" Alena shoots back. "And how hast thy clothing been forsaken?"

"I was just looking in the chemistry lab!" Sasha shouts. "There must have been a problem with the equipment!"

Sasha blushes and looks around the room, noticing Alena's magic bag. "Wait...did you tamper with school equipment?!"

"I would never do something so uncouth," Alena defends. "I merely asked the gods to find a way to prevent you from interfering in our future plans as lovers."

Sasha whips around to you in anger. "Did you two do this to me?!"

You hold up your hands in defense. "I just wanted you to leave me and my girlfriends alone! I didn't know THIS would happen!"

Technically, that is true. You had no idea Alena would somehow destroy all of Sasha's clothes while she was with you in school.

Sasha turns her frustration back to Alena. "Alright, look; you're always wearing three times as many clothes as you need. Just hand me a coat or something, and I'll consider the matter settled."

Alena lets out a dark laugh. "You anger an avatar of the dark ones, and you dare to ask for mercy? Thou art as foolish as thou art heartless. Farewell, my vanquished foe!"

Alena turns to the window and opens it before turning back to you. She blows you a kiss from over her mask. "Farewell, Harbinger of my affections!"

She makes a small tumble out the window, taking her bag with her. A few seconds later, you can see her figure calmly strolling down the parking lot.

"How did she do that?" You ask. "We're not even on the first floor."

Sasha glares at you, as if she wonders why that was your biggest questions. She grips herself with her bare hands as she tries to keep her nudity as hidden as possible. You, meanwhile, now find yourself alone with your naked sexy principal.
