You and your class were doing a game to get the blue cup to the top and the red cups on the bottom.

When your team went up he smirked and bit his lip as you stroked the cup you couldn't use the table nor your stomach.

Your team won and after class he pinned you against the wall and smiled playfully.

"Where's my turn, darling~? Maybe you'll even use your mouth to help you out.."

He smirks and chuckles.
