Doing the Nasty: "Hap and Leonard" by Joe R. Lansdale
Published 2016.
“I went upstairs and locked the door and took off my clothes and slid under the sheets with Brett. She was sitting up in bed with pillows at her back. She had the shee pulled up over her. She had her reading glasses on, pushed down on her nose. She put the book in her lap.
‘I hope you don’t think you’re going to get any,’ she said.
‘Any what?’ I said.
‘Don’t act coy with me,’ she said.
‘I just got naked,” I said.
‘It has nothing to do with you. I’m comfortable naked. Some of us are quite comfortable with our bodies, our nudity.’
‘Oh,’ she said.
‘Yep.’
‘I’m reading, you know.’
‘How’s the book?’
‘Sucks.’
‘So, you want to do the nasty?’
‘That is far from romantic,’ she said. ‘But lucky for you I think a lot of that stuff is nonsense. I’m not as girly as I look. And then again, the book sucks, so that makes your suggestion a little more interesting.’
She laid the book on the bed beside her. She dropped the sheet. She was naked as well.
‘Surprise,’ she said.
There's not much else, but read on If you feel so inclined.
