I'd flip her around and fuck her square in her asshole. When I was getting ready to nut I'd pull out and shove it in her mouth and make her take it while I was throat fucking her.
Pull those panties to the side and slide it in my slut. Grab her hips and fuck her hard. She's good with either hole and she likes cum in either of them.
This was right in the middle of us fucking and I wasn't done, I ended up fucking her in the ass and leaving my load in there. I ate her pussy when I was done and I got a little cleanup and cum from her asshole.
