Yup, and Kurumu gets 'punished'

"All right, Miss Shizuka. Since you wone, get up on the desk, I'm going to plow you."

"Meow~!" She says, getting up and onto the collection of desks they had moved together for the club meeting. She wiggled her put for Tsukane, tail wagging a lot in anticipation as he moved behind her, dropping his trousers. Kurumu starts getting up to get a better view, before feeling a firm hand on her head. Turning to look up, she saw the Inner Moka looking back down at her.

"If I recall correctly, you lost the race~" The vampire's inner side said, grabbing Kurumu's unoccupied chair and moving it to the succubus's other side. "As punishment for not living up to your sexual reputation, you're going to keep going until I say stop." She proceeded to put the blue haired girl's head directly in front of her snatch, lifting her legs up to squeeze Kurumu's head between them, the other chair a footrest.

Inner Moka reclined, enjoying Kurumu's ministrations as she watches Tsukane plow their homeroom teacher. Shizuka was mewling with every thrust of Tsukane's cock, enjoying every thrust. "rowr, mrow, mroOOOOW!" She cried out loudly. Inner moka was slightly worried someone in the halls could hear, before being distracted by Kurumu bringing her to orgasm, Tsukane following suit with their teacher joining in the climaxes.

After a minute, Tsukane withdrew from Shizuka as Outer Moka let Kurumu out from between her thighs. "That was good, Ms. Shizuka." Tsukane said through a series of pants as he sat down.

"Glad you had fun, Master Tsukane~" She said with a coy wink. "Anything else you'd ask of this slutty kitty~? Nya!" she gave a little paw scratch in the air for the added cuteness factor.

"No, I think that was enough for today, we should clean the classroom. Back to Teaching." Tsukane said as he shook his head, letting Kurumu and Shizuka gather their clothes. Shizuka got dressed first and stood up, looking at Tsukane.

"I must admit, as odd as it was in hindsight, it was pretty fun. Teachers like me work pretty hard, so it was nice to get a break from grading papers." She said as she looked over the group. "I hadn't gotten to your paper yet, Tsukane, but Moka did top of the class again~." She beamed at Moka, who looked quite pleased.

"And me?" Kurumu asked hopefully, Shizuka turning her attention to the succubus with a very different look.

"..I'd say you need to focus in class more." Their homeroom teacher shook her head at Kurumu, the blue haired girl's head dropping, before making puppy dog eyes at Tsukane.

"No."

"C'mon, pretty please?"

"No, I'm not making Ms. Shizuka buff up your grades." He said grabbing the Sex Note. Before Kurumu could react or think of reaching for her secret sheets of Sex Note paper, Tsukane had already written a new rule.

Kurumu Kuruno cannot use the Sex Note on Shizuka Nekonome.

He showed her the rule, making the succubus pout harder.

"Thank you, Tsukane. I do hope the rest of my students are as honest when it comes to their academics as you." Shizuka nodded as she approached the door before stopping and making a phone gesture with her hands. "Call me soon~" She said as she headed out the door.
