The next day starts off normally. Jeff and Jenny are both coasting at this point as they're seniors and already have college lined up. They're both in Ms. Gofel's class just prior to lunch along with Amy. The seating arrangement is by first name, which had Jeff and Jenny sitting next to each other with Amy at the front of the class.
"I know we're wrapping things up," Ms. Gofel announces to get everyone's attention, "but we do need to go over this last topic with derivatives."
As she continues to talk, Jeff and Jenny look at each other and smile. They don't like Ms. Gofel much as she is on the stricter side, but being able to sit together made it bearable and they used it to their advantage. This is also the first time they've seen each other today.
Jeff knows Jenny's expressions well and he can tell something troubling her. After taking some notes, he whispers, "What's up?"
Giving Jeff a sideways glance, she sighs as she whispers, "I think Amy wants to become wolfened."
Taken aback, Jeff shoots a glance toward his sister then looks back to Jenny as he raises an eyebrow.
"We talked yesterday, last night, after I left. She stopped me on the sidewalk. We talked for a while and she seems to want it more than anything."
"No way..."
"I don't know how I feel about it either," Jenny sighs in uncertainty. "She was really insistent though."
Leaning more onto his elbow so he's closer to his girlfriend, he asks "What did she say?"
Taking a moment to lean closer too, she whispers, "She has the same furry desires that I had."
Jeff nearly chokes as he looks back to his sister.
"I think she's jealous of you too. You got to become a wolf and that’s something she’s always wished for."
Taking a moment to collect himself, he shifts his eyes back to Jenny. "I guess I understand. But that means she'd need to..."
Jenny can't help but laugh at the innuendo. Realizing her mistake, she quickly hides it in a cough and grabs her water bottle to sell the lie as Ms. Gofel looks in her direction and appears appeased as she goes back to her lecture. Leaning back on her elbow, Jenny explains, "She knows more about this than we do. I'll say more at lunch."
"How does she know?"
Giving a slight shrug, Jenny considers. "She's lived in this reality her whole life. I'm guessing the internet has a lot of information about being wolfened too though I haven't looked yet."
Sitting back, Jeff breaks the secretive conversation as he thinks about everything. Ms. Gofel's monotone voice becomes background noise as he looks back toward his sister. He tries to picture her as a wolf but its hard as he's only ever seen Jenny as one. He had never considered it before but Amy had always been a little different than most girls and women. And if Amy did become a wolf, it'd be nice to have his sister as a pack-mate.
"Shit!" Jenny exclaims softly toward Jeff.
Looking over, he nearly jumps out of his seat. Jenny's naked and has a purple collar around her neck! "Jenny?"
Ms. Gofel stops talking and looks over at Jeff. "Mr. Smith? Is there something you'd like to share with the class?"
Staring, mouth agape, Jeff looks from Jenny's naked form to his teacher then to the other students. Why is no one else looking at Jenny!?
Shaking her head as if in disbelief, Ms. Gofel says, "Why are you acting so surprised? She's just going into heat. I was informed that you're wolfened now too. If you want to assist her go ahead."
"What?!" Jeff exclaims.
Putting her hands on her hips in an authoritative way, Ms. Gofel leans over her lectern and says with a strict tone of voice, "You heard me. Take care of her needs as I continue the lesson. Just try to keep it quiet!"
Amy turns around and sees Jenny sitting there naked as if nothing's wrong; but Jeff can see a burning desire in her eyes. No, not just burning, they're twinkling like a star going supernova! She's planning something. Looking back to Jenny, he can see her groping at the newly formed teats lining her belly as she moans.
"Oh!" Jenny says breathlessly, "They feel amazing!"
Ms. Gofel turns back to the board and starts to drone on as Jeff leans over to Jenny and whispers, "What do we do?"
"Just do what she said. Help me with this!" Jenny whines as she gets up and walks to the back of the classroom as Jeff dutifully follows. Bending down, Jenny gets onto her hands and knees as fur starts to grow over her body. "Fuck me, please!"
Looking around, Jeff sees that everyone in class is taking notes as Ms. Gofel continues her lecture. "Now!?"
"Please, Jeff?" Jenny asks softly as her fingers shorten and her legs start to shrink with a grinding noise. "I need this so badly! Fuck me!"
Watching the fur growing over Jenny's back is entrancing and he can also see a tail starting to grow from just above her butt. He can feel his own arousal growing as his cock hardens as he she continues to moan and her tail pushes to its full length as grey fur covers it. She looks up at him with wanting eyes as her ears become pointed while they move to the top of her head as her hair grows into her scalp as it becomes grey as well. She’s also visibly smaller now as popping noises come from her shoulders and hips.
"Please!" she begs again as she moans more. "Weff. Wease! Wuck we!"
As Jenny’s mouth pushes out into a muzzle, Jeff wonders if he should just pull down his pants and mate with her as a human or if he should become a wolf first.
