"what are you doing today?"
From Create Your Own Story
She laughs, "for fucks sake Alex, that's not funny, I was worried."
"I'm touched," you joke she lays down perpendicular to you and places her head on your abs, she is yet to notice the tent down below.
"Happy birthday big 18"
"thank you, so much new responsibility" you examine your sisters skinny body from the side as lay down on your bed, her tits were small but perky, and you preferred that to massive tits.
"Yep you got start taking care of yourself" you say not really paying attention, instead your looking at her skinny stomach, she didn't have any abs, but she had a long skinny torso. You could almost imagine your dick being thrust so deep inside that you'd see the outline. You could imagine yourself cumming all other her cute belly button and her small erect...
"...ALEX," you snap back "are you even listening to me,"
"Sorry I zoned out"
"No, you were staring at me, and....oh" she finally saw your even larger tent which had now risen past her face
She suddenly stood up by your bedside, "Alex, why the fuck are you hard?"
"sorry, that's why I called you, My balls are in so much pain"
