"Well I think I'm gonna go wash up. You coming Rise? Your face is all messy like mine. Can't use peroxide again or the school might blow up the next time" Nana Nishigaki said as she grinned to herself.

When the couple had returned from washing their faces at the sink, they went to take their seats at the long tables of the science lab.

Nana stood with her eyes wide opened and arms folded. Instead of pulling out a stool to sit on, Rise sat on the lab table, facing her girlfriend. Using her index finger, she beckoned Nana to come closer to her.

Nishigaki-sensei, as if she was in some trance, walked over slowly to the table that Rise sat on, neither blinking.

Rise grabbed Nana by the black scrub top she wore and pulled her into a kiss. Nana's heart pounded and she returned the kiss with even more fiery passion.

The younger girl tossed her head backward, giving her lover access to her now exposed neck. Softly and gently, the silver-haired scientist dipped her lips forward and started to lap her lips over the creamy surface. The raven-haired girl let out several sighs of contentment at the feel of her girlfriend's lips on her neck.

Smiling to herself, the older girl proceeded to suck on the nape of the younger girl's neck. Rise's breathing deepened as she tightened her arms around Nana's back. Having been together for a while, Nana memorized all of Rise's weak spots.

Rise couldn't resist this. She just wanted to spend more time with her girlfriend and hear her erotic moans. It was as if she was addicted to the carefree woman in front of her. Rise was now tugging on Nana's white lab coat, silently begging for more.

Rise's breath hitched as Nana began kneading against her breasts.

Suddenly Nana felt something in her stockings. She glanced down to see it was Rise's right hand snaking its way to her soaked panties.

The student council president brushed her thumb over Nana's moist clit, causing her to shudder. The petite girl repeated the motion twice, thrice, several more times, and each time, the motions of her thumb deliberately slowed as she swept it across the woman's love bud.

Nana thought her mind would explode as every agonizing slow movement had sent a thrill of pleasure through her body, causing her to gasp, heart beating erratically as the area between her thighs burned and twitched. Nana could feel her own wetness seeping through the thin white cloth that covered her lower region. Meanwhile she kept massaging Rise's stiff breasts, even harder and faster. But she felt weak in the knees as Rise continued to gently caress her most sensitive place.

"Rise-chan…please…haah…stop…teasing…" the teacher panted. She had to resort to begging her lover as her body burned and trembled with desire. She couldn't take it any longer. She needed Rise in her. She moaned helplessly as Rise's finger finally entered her dripping slit.

Nana reached under Rise's skirt. She let two digits wander inside Rise's welcoming core. Slowly Nana started to push her fingers in and out of Rise's region. Nana's own breathing was getting heavier as her lover did the same to her. Unconsciously Nana's hips were moving rhythmically, in an attempt to feel more pleasured by Rise's soft fingers. The harder she thrust her hips forward, the more she could feel herself drowning in the sea of hot sizzling pleasure.

Neither young women could think straight as their vision started to turn white.

"Haaaahh…I'm going to…I'm going to cum…I can't hold it in any longer…Aahh" Nana hissed.

With a final thrust from both parties, their bodies gave a violent jerk and then both convulsed with orgasm.

Gasping and panting for breath as they basked in the afterglow, Nana's knees buckled. She would've collapsed on the floor if not for Rise hugging her tightly. The 15 year old hugged her teacher even harder as she felt Nana shudder in her arms.

When the 26 year old woman finally caught her breath, she spoke up.

"That felt amazing Rise, and explosive too." she said as she stared into her girlfriend's wine-red orbs.

Rise leaned in to kiss her lover once more before they prepared to go home for the weekend.

A/N: Hope you enjoyed this little smutty shot. I thank my friend Yurichan220 for giving me the idea and encouraging me to write more Rise x Nana. Also big thank you to all of my readers. Without your support, I can't write so thanks again! BTW up next, Rise comes out to her father. How will her father react to her relationship with her teacher? You'll just have to read to find out.
