Inside you

Falling on top of Mira, your breasts pressed into her own massive chest, your head beside hers, sweating and panting, you breathed into her ear.

"You can cum in me. I want you to cum in me."

"Fuck yes! Here's my cum!"

Mira's thrusts get erratic, she pushes her cock deep into you and streams of hot cum shoot inside of you.

"Oh Mira," you moaned, continuing to fuck her as much as you could, enjoying the hot feeling filling you up as her cock pulsed inside you.

Blissfully happy, you didn't move. With loads of your step-sister's cum in you, some of it leaking out. You just lay on top of your sibling.

"See, wasn't this better than drama with our parents?"

"So much better," you agree, lifting your head and kissing Mira on the lips. "And we have a whole weekend before they get back."
