Gokuusu Mizugi de Oka●retagari ga Kakusenai

"Sensei, you promised to have sex with us if we became national champions!!"

The swim team advisor Natsumi jokingly offered them sex if they won, but the boys took it as a serious promise, so they pushed themselves desperately to take the championship. Now they won't let her off the hook.

While Natsumi continued resisting in vain, she gradually began to notice her inner desires. She may be their advisor, but she's also surrounded by fit and healthy boys. Her intrusive thoughts are saying she wants to get ravished♪
