'H-hai, Negi-sensei!' (That's 'yes, teacher', by the way)

Nodoka: Yes....yes, it is what i want, Negi-sensei. But...but only if it's with you.

She smiled weakly. Negi however looked at her seriously. If sex was what she wanted, she would have it. Negi reached behind her and unhooked her bra. She gasped.

Makie: Hey! I thought you didn't know how to do that.

Nodoka made a feeble attempt to catch her falling undergarment, but only ended up putting her breast on Negi's chin.

Nodoka: S-s-sorry!

Negi said nothing, instead opening his lips and taking the nipple in. Nodoka gasped, moaned and tossed her head back slightly. While sucking her, Negi ran his hands over her hips, legs and ass. He had neglected Makie's ass, and he wouldn't make that mistake again. He softly gripped Nodoka's firm, smooth ass, which made her moan quietly. She closed her eyes and held Negi's head to her chest, her hips starting to sway back and forth on their own.

Nodoka: EE!

Makie: What!?

Nodoka: I-! I-! I th-think i finished the first part of your challenge, Makie.

Makie: He's up again?! Lemme see!

Makie reached between Nodoka's legs and grabbed Negi's cock.

Makie, giggling: You sure did. Good job! But you're not done yet, Bookstore!

Nodoka: I-I know! I'm j-just getting started, Makie!

Makie, thinking: Feisty! She really wants Negi-kun to herself. But....i want him too. If i help Nodoka out with this, i'll get to be sexy with Negi-kun one more time, but she'll get him for sure. If i try to mess her up, i'll keep Negi-kun, but she'll hate me AND be heart-broken. What should i do?
