I got a sudden call late on a Saturday night.

"I missed the last train, so let me stay the night."

It was her younger sister, Ui.

I thought I'd refused, but a few minutes later the doorbell rang.
And she came into my house without asking.

She seemed to have had some alcohol in her system, as she was even closer than usual and touching me a lot.

And her chest was loose too...
She was pressing her breasts against me so much that I wondered if she was trying to seduce me on purpose.

What would I do if she found out...

"She said it was touching me a little."

"Hmm? You're touching me? On purpose."

Oh, maybe I'm in trouble.
