She screamed with pain from your body being forcefully pushed inside her vagina. You tried getting your head out, but it was no use. You slipped in, you feet entering the small space. You pushed against the walls as you yelled out. Your sister fell on her stomach, squishing the small area of breathing room you had. You whined as she struggled to move around.
"G-Get out you perv!" She yelled at you.
"I can't! I'm stuck!" You yelled back.
