You arrive bright and early.

You knock on the Hendersons’ door. The sun’s barely up, and you’ve been fighting an erection all the way here.

“It’s not locked.” a voice from inside shouts. You open it and step inside. “We’re in the sitting room!” comes another yell. You hurry through.

The girls look fantastic despite the early hour. Kate is dressed in a short tee-shirt and some tight shorts. Her midriff is bare, and you can see her belly-button piercing glinting in the morning sun. She’s sitting down with her legs apart, and you can see a damp spot on the crotch. She must not be wearing any panties – and must have been really looking forward to your arrival.

Jo is wearing a purple sun dress. The skirt is cut to mid-thigh, and the low neckline means her tits are near to spilling out.

April is wearing a halter top, and has dressed in a skirt even shorter than her mother’s. It wouldn’t take much for her to be flashing her panties. If she’s wearing panties…

What the hell. You won the bet. You reach down to check. Startled by your bold move, April blushes and holds her skirt in place.

“Come on, sis,” Kate says. “Don’t forget he owns your cunny now. Why shouldn’t he have a look at it?”

Jo smiles at you and her daughters. “We talked some stuff over yesterday. Firstly, the safe word is ‘magnesium’. We’ll say that if there’s something we really don’t want to do. Otherwise, we’ll do whatever you want, and you can do whatever you want to us – even if we complain or struggle.” She licks her lips at the thought. “Secondly, we’re assuming you’re going to be moving in here for the duration of the agreement. I’m sure you can find a bed to sleep in. Or three. Was there anything else?”

“Our bet, mum,” April reminds her.

“Oh yes. To add a little extra interest, we’ve each agreed on a competition between the three of us. We’ll each pledge two hundred bucks to a pool. At the end of the month, three hundred goes to the one who you’ve fucked the most, and three hundred goes to the one who’s got you to do the kinkiest, most perverted thing to her.”

“That way we’re proper whores,” Kate says eagerly, “doing it for money, and not just ‘cause we think you’re hot. Oh, and no showing April favouritism just ‘cause she’s your girlfriend. We want this to be a fair fight.”

April nods. “Yeah. For the next month, I’m not your girlfriend, I’m your fucktoy.”

“Alright, then,” you say, eager to try out your new authority. “April, bend over, brace yourself on the sofa, and stick your arse up as high as you can.”

April hesitates for a moment, and then obeys. Her skirt’s so short that you can see her backside and pussy fully displayed. Her tight snatch looks a little moist.

“A mother always worries about how well she’s taught her kids,” Jo says, “but whatever else I’ve taught these little sluts, they know that fresh whores don’t greet their master wearing underwear. Now, do you want a quick fuck before I make you breakfast?”

You consider your options. April’s pose is very tempting. But then again, you still haven’t had a chance to get inside Jo’s pussy, or to do anything with Kate.
