Saw you thinking you'd been perving on her!

Kim lost her footing, slipping forward and smashing you with her dick head. Your entire upper half slid into the hungry urethra during impact.

"Ah! What was that?" Kim asked herself out loud. She lifted her massive limp dick to look at the sudden intrusion. "Ew! Did I catch a bug!?" She screamed. Kim started hitting her cock head against the ground in an attempt to kill the "bug" that her penis caught.

After just finding out your sister had a penis, you had learned a lot. Like the fact that it constantly leaked precum. After a few moments of rough movement, you slid out of her urethra. With only a split-second to react, you looked up to see that Kim didn't know she already got you out of her dick. Her penis was speeding towards you and you had no way to defend yourself from it.

*SLAP*

The meaty dick smashed you into the ground. Luckily it wasn't hard. An erect penis of that size has the potential to crush you to ****.

"Ha! I got got it!" Kim congratulated herself. She sat there for a moment, content with the fact that she had presumably ended the life of a bug with her dick. "Wait... Is it still alive?"

Kim lifted her penis once more to find you stuck to the bottom of her dick head.

"Will...? Is that you?" Kim asked. She was sure she was seeing things.

"Yes! I was trying to get your attent-"

"You're such a pervert! You snuck in here to peep on me, didn't you!" Kim objects.

"No! It's a misunderstanding! I swear that wasn't what I-"

"Yeah, sure! You've always been a bad liar! Since you wanted to see me naked so bad, lemme show you how I pleasure myself!" Kim interrupted. She clearly didn't believe you. The way things were going, you'd definitely end up in a dangerous position.

Kim pealed you off her dick and held you in the air.

"How'd my dick smell? I always wash it, but I can never get rid of that musky smell that emanates off it. At least it makes it easier to punish scum like you!" And with that, Kim put you half way under her foreskin. Her cock was erect now, and it was somehow even more massive than before. It was thicker than her arm and nearly reached her tits.

"I was just going to shave and go on with my day, but for some reason I'm a bit horny right now..." Kim said, pretending that she didn't know you were there. As you comprehended this she began striking her massive dong. She was very rough and quick, pumping both hands up and down the massive shaft trying to cause the most friction possible. Every time her hands reached her tip you were enveloped by her stretchy foreskin.

The temperature increased greatly after only a few minutes of fapping.

"Is this what you wanted, Will? Do you enjoy being smashed against my huge dick head?" Kim asked. She was getting off to the fact that she could overpower her miniscule brother with only her dick.

She stopped pumping her hands and got on her hands and knees. Kim jumped the ground with great ****, trying to release her thick spunk. Her libido was clearly insatiable. With the increasing roughness you were **** completely underneath her foreskin.

From under the thick sheet of skin you could feel her cock twitching.

"Kiiim! Alice and I are going to the store! We'll be back in an hour or so!" Your mom yelled. Now you were stuck with your sister. She made it obvious that she was the true pervert here.

"O-okay, mom! Bye! You hear that, Will? It's just you and me now!" Kim said, staring down the barrel of her dick. She couldn't see you, but she could feel your squirms.

"Since we're alone now, you wanna try out some toys? I think mom has some sex toys in her room somewhere. Ooh, she also got a watermelon yesterday. I've never fucked one of those, let alone fucked one while punishing my perverted brother..."
