I painfully work a *giant* dildo into Nina. It’s not especially long, but it’s very thick. Once it’s in and they've calmed down, I start pounding on it with a mallet, then shoving it in and out. At some point they're making complain-y noises and I note how bright-eyed they are, and they make a great little embarrassed face. Eventually we upgrade from the dildo to significant amounts of my hand, then finish off with some hard asshole spanking.
