Cutting Corners (con, casual)

"Hey… Sis… Wake up…" - I gently tapped her a few times to assure she hears me.
My sister, as a lazybone she is, tried to fake her sleep, even though I was sure she already woke up
"Whah do you want" - She finally turned to me and moaned in a soft morning voice
"Sorry, but I came in you a few times while you were asleep… You might wanna take a shower… to get all the cum out"
"I don't wanna" - She turned back away from me - "Leave me alone"
"But what if you get pergnant? You already could be!"
She took a knife from under her pillow, lifted her blanket and stabbed herself in the stomach a few times, then twice in the vagina and left the knife there
"Does that solve your problem..?" - She said with difficulty
"It does"
"Cool… Now leave me alone…"
If there was a child at some point, it thankfully died. As for my sis, I fucked her later in her tummy a few times
