I will try my best to make this for both genders.

Sawada Shin:

he pulled your underwear off and kissed the inside of your thights close to your private place. Moan left your lips. Heard door open so both looked and saw Kuma ask if your okay thile he saw you two. He dropped his food out his mouth into his bento and told you two need help. He left and you did hands infront of face and Shin chuckled before kissing you.

Uchiyama Haruhiko:

He held your hips and slided inside you. Moaning in pleasure. Both heard Minami say to not fuck at school and left. Uchi did his face in your neck and mumbled Minami isn't gonna let this slide and will be teased for life. You laughed and kissed him.

Noda Takeshi:

he saw some porn video and said hew anted tot ry the position. So you moaned as he was sliding in slowly before you screamed loudly as he hit your spot and heard door slam open. Uchi was about to ask what wrong is and then he slammed the door close fast.

Kumai Teruo:

you both playing some weird sexy game. It was to put whip cream on sexual parts of body and lick it off. He did it on your breast and was about to lick when Sawada entered. Eh mumbled his eyes are hurt and left. You hit Kuma with a pillow for not locking the door.

Minami Youichi:

You two are horny bastards so always want each other. He pinned you to wall. Commanded to jump so did and wrapped legs around his waist. Kissed him deeply before hearing Noda's laptop fall and he apologized before running out. He even hit a wall on the way out.

Yamaguchi Kumiko:

Held her waist and kissed her while having her pinned on the bed. Did hand in her hair before hearing something fall and looked. It was Tetsu and he bowe dbefore running down the stairs. You stared before rolling eyes and contiued while Kumiko hided her face embarrassed in pillow.
