Based on the hentai: Boin Lecture. Changing it up a bit. So shut up.
Sai was a new teacher in an All-Girls School. He quickly became popular with his peers, and especially the students.
"Morning," he said. "Good Morning, Sensei," they all chimed in unison. All the girls were charmed by his attractiveness. Then one day, it all changed.
"For extra credit, you may come after school hours and tell me what you would like to be when you're older. I will give you a script and a costume, and you will act your occupation out for me. See me after class."
The bell rang, and only one pink-haired girl with cute green eyes came. "I'd like to be a nurse, Sensei," she said. Sai smirked in his head. The Plan was going just as he expected. He reached into his drawer, pulled out a script for the "Nurse Occupation" and handed it to her. He said, "Go to the hall, then make a left to the Dressing Room. Pick out a nurse outfit there, and then enter Room 106. I'll be waiting," he said as he left the room.
The girl's name was Haruno Sakura, and she fell HARD for Sai's looks. She went to the Dressing Room and saw all these cute outfits there. She picked a short, (And I mean SHORT) sexy pink outfit with long white socks, pink sandals, and a pink matching nurse hat. She went to Room 106.
Dai was waiting for her on a cot. He stared dreamily at her bigger-than-Tsunade-breasts, like they were over-inflated kickballs, which they kinda were. He finally said, "Okay, let's see what you got." She started, "Mr. Kanai, you're not the only one who's afraid of surgery," she said. "EH?! Easier said than done!" he responded back. She then said, "Fine, I'll let you feel my heartbeat. Put your hands and ears on my...chest!" She gasped. Sai was hugging her, with his head on her waist and she said, "Sai, stop, this wasn't on the script." He looked up and put his hands on her giant breasts, and started rubbing them. She moaned. "But Sakura, if we go by the script, how can we tell if you're fit to be a nurse?"
She thought, "No, I cant hold in my moan. How can I resist when it's Sai??" She gently pushed him away and said, "Sai, um...Since it's so hard to feel my heartbeat under all this clothing..." she unbuttoned her tiny outfit, revealing her blue bra and panties. She let the clothing fall to the floor, and unhooked the bra, falling with the clothing. All that was left of her was her nurse hat, her thong, and her shoes. She blushed while Sai gaped at her beautiful breasts.
He made her sit next to him, on his left. She moaned while he put an arm around her and started rubbing her right breast clockwise. He then switched over to her nipple, causing her to moan even more. "Sakura, you like it?" he said in a husky voice. "I-I don't know," she responded. "You are stubborn." He continued rubbing her nipple. Then he laid her down on the bed and she said, "No...Don't concentrate on the nipples..." He refused to listen, and put his mouth on her nipple, rubbing the left breast then. And then he said, "See? Your nipples are hard." She responded with a moan, "That's because...You keep touching them..." He smirked, then continued with his process.
She moaned again and again. "Sai, stop, this is embarrassing, very embarrassing," but he didn't listen. He kept rubbing her breasts, enjoying the feeling, while he listened to her enjoyable yet pleading moans. She loved it; she just didn't see it yet.
End of Chapter 1.
There is nothing anal-y in this story: I don't like that kind of stuff.
