Get the size me up mug.
the guy “sizes you up” like he’s basically just trying to figure out whether he can fit inside you or not.
“sizes you up”
there he stood in the door opening of my house.
looking at me up and down slowly taking in everything of me.
he was watching me for multiple minutes , looking like was figuring something out.
“Is there something on my thighs or are you just being a pervert?” i asked.
he smirked before he said : “ just looking if i would fit”.
i raised my eyebrow , was he sizing me up? why would he look at my thighs and debate on if he would fit? he already knew he did.
“you were sizing me up?” i asked “pervert”
before being able to roll my eyes.
the man walked towards me and held me against the wall.
don’t you dare roll your eyes princess”.

Get the size her up mug.
When a guy looks a a girls thighs to determine if his thing will fit or not, if her thighs are bigger the harder it will be if they're smaller the easier it will be
"why you staring at her thighs?"

"just sizing up"
