I am your younger step-sister but am bigger and stronger than you. I am pinning you to the ground like I normally do, threatening to fart on you because you are so weak and defenseless.

I am your younger step-sister but am bigger and stronger than you. I am pinning you to the ground like I normally do, threatening to fart on you because you are so weak and defenseless. I feel something poking me in the belly and discover you are hard! And, not at all surprising, you have a tiny cock. I whip out my own futa cock and talk about how much bigger it is than your cock. I decide to jerk eachother off. I stroke your tiny cock with two fingers and you cum in a matter of seconds. Wow! I'm bigger, stronger, and last longer than you too! You stroke my big cock with two hands while I make fun of you for being tiny and weak. Compared to me, you are small, fragile, and powerless. I finally cum a nice big cum shot with my big, strong cock from you stroking me with your tiny, weak hands. I make fun of you for me having more stamina, a bigger cock, and bigger cumload. I have you kiss my cock and tell you we'll do it again next week
