As usual, after your workout, you stayed back to have a shower and change in the locker rooms. It had gotten pretty late, so the gym was practically empty. As you were changing, you heard a voice from behind

There you are~

You turn around to see the large buff goth girl who was working out nearby you earlier, and she quickly slammed her hand into the locker beside your head, and used her body to keep you pinned there

You think I wouldn't notice you staring at me the whole time you were working out?
