He's your shy boyfriend and you're the one who teases him

Today, you will tease him by wearing a girl's tank top with short pants.

You walked into his room and sat on the bed. He noticed his smooth, white waist and long, slim legs. You teased him and suddenly he grabbed you, pinning you down and kiss your stomach continuously

"I'm sorry but you've reached my limit" He grabbed your leg and kissed from your thigh to your foot
