Chapter 23

"I'll rub it on for you♡ Senpai" (塗ってあげますよ♡センパイ) is the twentythird chapter of the Don't Toy With Me, Miss Nagatoro manga series.

Summary
Nagatoro and her friend/rival had a swimming competition arbitrated by the third girl. Nagatoro won and began to brag about how good she was as a member of the swimming club, causing her friend to remind her she was just a "bench-warmer" in the team and also they both swam in the front crawl rather than the breaststroke, which is the swimming style the club used. Then seeing Nagatoro wasn't listening to her but rather looking at Senpai all alone under their parasol, she tried to cheer her up telling her that if he didn't wanted to swim they couldn't force him.

Feeling bad for him however, Nagatoro went to Senpai and asked him if he managed to drew something and why he wasn't swimming, prompting him to confess he wasn't that good at it and also had huge fear of getting sunburned. Then Nagatoro offered him the 50+ sunscreen she had brought and stripped him discovering he was actually wearing a swimsuit under his clothes; as she asked him to lie down so she can rub the sunscreen on him, however, Senpai replied that that would have been something boyfriend and girlfriend would do, pointing out that they are not. Feeling irrationally offended by Senpai's words, Nagatoro pinned him to the ground and started to rub the lotion on him with her foot in retaliation.

However both of her friend soon joined her in giving Senpai said treatement, prompting Nagatoro to stop, although they ended up using the whole bottle and fully covering him on sunscreen. After Senpai was eventually convinced to enter the sea, he discover he could float easily, prompting Nagatoro to told him it was way easier to float in salt water rather than clean one.

Senpai and the three girls ended up having a good time, making another swimming competition together, playing with sand and eating ramen at the beachside. Later, while looking at Nagatoro playing volleyball with her friends in front of the sunset, he felt inspirated and drew a pencil sketch of her.

The next morning, as Nagatoro asked him at the phone how did he felt about having come to the beach with them, Senpai admitted that it was actually fun.
