The "Netorare" in the title doesn't reflect the content of this gallery, so do not tag it... not yet anyway, this is Ayoyagi Kabota after all, so it might happen if he chooses to continue this and go that route.
This is about Shion teasing her boyfriend Yuuta about really going out with her college mate on a party she was invited over after senpai drops Shion off, Yuuta pleads her not to go under the fear of the handsome senpai getting Shion drunk and ravaging her; Shion dares him, if Yuuta cums in less than 5 minutes she will go, he loses so Shion teases him about being a cuckold who came fast as he feared Shion would be taken by someone else... then she instantly drops her dominant attitude, saying this is just a joke, the one who gave Shion a ride was a girl, she will never cheat on Yuuta, he is her one and only love.
