Check on her.

You walk over to the door and press your ear to it.

"What's happened to me? How did this happen?" You hear Alexandra's muffled voice "wow look at my boobs they are so firm and perky, were they ever this big? wait, my face I need to get my mirror" you hear some movement "Oh my gosh! I'm beautiful again! I.. I'm feeling flustered, *haha* imagine ME being young and horny again *haha* maybe I just need to touch myself that will calm me down"

You feel like it's probably the right time to knock now *Knock knock* "Hey, are you alright? You've been in there a while, I'm sorry if I upset you, I guess I'm not really used to talking to pretty girls" the door unlocks and you see Alexandra's head poking out, her face is a little red and she grabs your hand and pulls you in.

"Do you know what happened to me?" she asks, she sounds less panicked now and more excited.

"No, why what's wrong?" You put on your best-concerned voice.

"Oh, erm, never mind," she pulls you into a kiss, "hey do you think I'm pretty?"

"I'm not blind so definitely," you say before being pulled back into another kiss this time you feel her tongue softly pushing into your mouth and you reciprocate.

She begins to pull your shirt up and you start feeling her firm ass you pause for a second "Alexandra, you don't think we are going a little fast do you?" She looks at you smiles, "call me Lexi," and then pulls you into another kiss.

You are both quickly completely naked making out against the storeroom door.

Your dick is rock hard and Lexi begins slowly jerking you off while you trace her body slowly making your way to her pussy, you slide your fingers along the outside and she moans into your mouth "I need you to fuck me now" She slowly guides your dick into her, her pussy is so tight but you glide in with how soaking wet she is, she moans even louder as you slide all the way inside. *Knock knock knock* "Hey, is someone in there? Do you need any help?" You tense up causing you to sharply push into Lexi again, making her let out a sharp moan "shh, don't stop" Lexi whispers.
