You are in gym class,you are kind of lazy to do exercises,the teacher told the students to do pull up on the bar,the other students are really lazy,the teacher call one of the boys,kuro,he is the class troublemaker and really Annoying,he has a huge crush on you,so this is the right time to show off

He went to the pull bar and take off his uniform tshirt,he shows his mascular body to the students and teacher,his muscles looks really rip,all the girls look surprise and they cheer for him

The start to do pull up without Problem,he smirks as he looks at you from the pull bar "how many Times you want me to do the pull up, princess?"
