Goes to your room

By: Mazomune

A mischievous smile covered your big sister's face as she walked further into your room.

"As long as I'm alone and I've got Willie's room all to myself, I'd better make the most of it!"

Kim skipped over to your bed, with you being jiggled between her cock and her balls as if you were in a roller-coaster. You wanted to scream at her to tell her off, but this really wasn't the right time. You felt her bending over and, wondering what she was doing, popped your head out from behind her dick in order to see.

She was picking up your underpants from the floor! Kim was always kind-hearted, but was she really cleaning your room for you?

"Ah, Willie!" She gasped aloud, thinking she was all alone "I wish I could tell you how I feel".

You were confused by what you just heard, but it all became clearer as she lifted your underpants up, presumably towards her face, and you heard her sniffing, breathing in hard. This was quite the revelation! You'd always thought your sister was cute, but you'd never dare tell her, and didn't think in a million years that she might return your feelings. You assumed it was just your disgusting fantasy.

"You smell so good" she said, shuddering with pleasure.

At this point, you felt the temperature rising in her crotch. Her sac tightened and her colossal dick slowly began to rise and grow. Kim flopped down onto your bed, lying on her back, and continued sniffing your underpants. It had become painfully obvious where this was leading.

"Oh Willie" she moaned again "your mouth feels so good! Keep taking it! Deeper Deeper!"

Your big sister was having a raunchy fantasy about you, lying on your bed and sniffing your clothes!

It was becoming increasingly cramped and stuffy in her panties as her cock kept growing. This thing was already huge when it was soft, but now it was getting enormous! Kim felt constrained like this, and slid a thumb into her panties so she could pull them down and release the beast.
