The two women, one on each side of the 18-year-old Caleb, marched him upstairs to his aunty's bedroom, a trip not made any quicker by Tammy occasionally stroking his stiff cock and then kissing him on the mouth.
"Tammy," said Mistress Diabolique, in exasperation after the third stop-for-a-smooch, "do you want to get this game started today or sometime in the middle of next week?"
The 25-year-old black domina laughed, and ran her hand over the teenager's stiffy.
"OK, and I thought you were all reluctant to have your nephew fuck you, Mistress D?" she asked her employer. "Now you're all of a sudden very hot to experience this youthful seven inches, eh?"
Debbie laughed at her assistant's cheek, but realised she was speaking the truth. She had decided to hold off fucking the well-muscled - in more ways than one! - young trainee sex slave, but now she had made up her mind that she was going to possess him, she was fucked if she wanted to be delayed in that task.
"All right, you got me, but let's get on with it, my pussy's getting wetter by the second," the stunningly-built 40-year-old dominatrix told the black bird.
"And mine's not?" laughed Tammy, as she finally let go of the youngster's erection and moved more swiftly towards the waiting bedroom.
Inside, Caleb was instructed to lie on his back in the middle of the big bed, then Tammy joined him, lying on his right side, while his Aunty Debbie got up and lay on his left.
Debbie looked at his stiffness, standing up and waving, not even lying flat on his taut abdomen.
"Now, we're going to play another numbers game," said his aunt, "only this one is more an endurance test. I think you'll like it. But I've got to warn you, you won't past it."
Tammy smiled and leaned over to stroke his erection, flicking the pre-cum drool from its knob onto his belly as she did. "Bet you can't last 10 minutes," she whispered, teasingly, in his right ear.
"Now, Tammy, he may do much better than some of our other fucks," said the 40-year-old domina.
"It was you who said he wouldn't last that long," said Tammy, "I was merely quoting you, Mistress D."
"Aunty," piped up the 18-year-old, "I thought you said you didn't let your sex slaves fuck you?"
Debbie grinned down at his eager, expectant face. "Course I did, silly," she said, "I don't. This is a game I play with Tammy, and sometimes another domme friend of mine, with men we particularly like. They're friends, not clients, and no money changes hands, so it's not prostitution, it's just an exciting sex game.
"As I say, sometimes it's three dommes on one slave, and it can be played with just one domme, but I find that two's the perfect number. Anyway, one, two, or three I know you're going to find it a lot more fun than fucking your lovely little Lucy!"
"And speaking of 'an exciting sex game', and 'fun'," said Tammy, sounding a little exasperated, "are you gonna explain it to him so we can get this fucking thing rolling?"
Debbie relented. "Very well, here goes. Right Caleb, the game is played according to mine and Tammy's instructions - we will call out numbers, and depending which they are, you will engage in a sex act with us."
Caleb nodded, listening carefully to his aunt's instructions.
The 40-year-old continued: "If I say 1, then you will kneel up by my face and place your knob to my mouth and I will fellate you. If it's 2, then you will tit fuck me. And 3 - well, you can guess what you do when I call that out, can't you?"
Caleb again nodded, keenly. "I fuck you in the cunt, aunty," he whispered, huskily.
