Put them in the bottom of the dirty clothes hamper.

I went into the bathroom and rinsed as much of my jizz off of the panties as I could. When I had them relatively clean I put them in the clothes hamper. Luckily there were some clothes in there already, so Samantha wouldn't notice them for a few days probably, and she may not notice them at all until after they have been cleaned.

After disposing of the evidence, I picked up my book and began to read until Samantha came home. She arrived a little after midnight. She appeared a little drunk; not ****, just a little buzzed.

"James, hi! How was your night?" She said slipping her shoes off.

"It was good. The kids went to bed around 9. I've been reading since then."

"They didn't give you any trouble?" She asked, dropping into the love seat across from me.

"No, not really. We played a board game before bed so they were fairly agreeable."

"Good. I'm glad. Anyway, I owe you some money." She began digging through her purse and came up with two crisp $20's. "I hope this is enough."
