There's Nothing Like A Slut - She's Human

"Hi!" Kelly's voice answers. "I was just about to call you!"
"Yeah," you say, trying to keep your voice normal as Jess fucks your ass with her tail and you fuck her tits, "How strange! What did you want?"
"No, you first!" she giggles. Cursed humans, wasting time.
"YOU FIRST, Kelly" you say, letting a little demonic edge into your voice.
"Well... since you put it like that. I've been feeling a little horny, and I was in the neighbourhood, so I wondered if you wanted to... you know..."
"Fuck like living sex machines?" you say.
"Wha... Um, yeah, I suppose." she laughs. You can hear arousal in her voice.
"When do you want me?"
"Now would be great, Kelly. I'm all alone..." You smile as Jess, who is frantically deepthroating you and licking your balls at the same time.
"I'll be there right away. See ya, sex machine!" she giggles, and hangs up.

You send Jess away to find another victim, and wait in the room for Kelly to arrive. Just like room service, you think, tasty slut breakfast on tap.

A while later there is a knock at the door.
