Yup. Oikawa was drunk and little horny, and figured Kageyama was too. So the plan, so much as it was one, was to have a nice fuck, then confess his feelings in the morning, followed by another round of sex.

Then go on and win gold for the Olympics.

Best plan ever.

Down to his underwear, cock half hard, he walks over to his bed, cupping Kageyama's jaw and leaning down to kiss him. "I want you, pretty boy."
