Mayo, hold the Tuna

>It was a standard summer night, not too hot
>Kaz had gotten his balls outta inside him and decided to ask Mayu out
>Walking over to her dorm, he gets ready to knock as he sees it cracked open with voices
>Peaking in he sees Mayu and Io sitting on the bottom bunk
>Their hands moving as they talk, discussing about school, life and Kaz
>Eventually, it just fades a bit to silence
>Io places her hand on Mayu's
>Mayu looks down at that and looks back up at Io
>Right before Io lays a big fat one on Mayu's lips
>Mayu pulls back a little, before going back in and going for it
>Their arms go up, holding each other's shoulders before Mayu pushes Io on to bed
>Squeeing a bit, Io grabs Mayu's ass, her hands going under her skirt
>Mayu is forcefully groping Io's chest, her hands cupping underneath
>Kaz is staring in horror, arousal, and sadness as he sees his crush with another person
>Tears in his eyes and a boner in his pants, Kaz walks away, dropping the roses he had in hand by the cracked open door
