The rest of the afternoon

You spent the rest of the afternoon resting and tidying up from the events of last night. Thankfully the place wasn't too much of a mess, just some couches that had been pushed out of place during some particularly rough fucking and some pictures that had become angled on the wall thanks to you fucking one of the sister's up against it. You held off from fucking Tracy again before Mia turned up as you wanted to save up your cum for the events of the evening, if last night was anything to go by. This wasn't easy considering she usually wore nothing but panties around the house all day, and sometimes not even that. Usually it wasn't a problem because you'd just fuck her whenever you pleased, but tonight was different, tonight you had two insatiable sluts to please.

Currently you were at the dining table, with Tracy in the kitchen grabbing a glass of water, wearing nothing but her panties.

"Your sister will be here soon slut, why don't you go get changed into something nice?"

Tracy looks over at you and smiles, "Yes sir."

She walks to the doorway to the kitchen before pausing and turning to you.

"Sir. What you said earlier, about Mia wanting to replace me. You'd never do that right?"

You look at her and smile. "Perform better than her tonight and you won't have to worry about that."

Tracy opens her mouth to respond but stops herself before she says anything, instead choosing to turn around and head towards your bedroom.

Whilst you're waiting you collect a variety of toys and equipment for your threesome tonight, including everything from vibrators to ropes. After a while longer of waiting, you hear the door bell ring and head over to answer it.
