Go check on the ladies

You wait in the kitchen for a while, having finished the chores, and wanting to give the girls some time to themselves. But then, eventually, you find yourself drawn to the stairs, even though you feel like you should rather be going for a walk or something. But at the other hand, it couldn't be rude just to check they're okay after all...?

You find the door to Rachel's room closed of course, and you don't really want to disturb them by knocking, so you just stand around outside for a moment and try to listen for their voices. It's really quiet in there however, which makes you wonder if they'd gone somewhere else for some reason, though it's easy to tell that they're not in the bathroom or your own bedroom either...

Then you finally hear something, just as you're starting to consider knocking after all, and instead you lean closer to put your ear to the door. You know it's a bad habit to go eavesdropping on the woman you love, but sometimes it's just really hard to keep one's curiousity in check!

Another sound pierces the silence, and this time you recognize it well, as you've had plenty of time getting used to it. The next one is slightly louder, and suddenly you've got a raging hardon going on, despite of the pang of jealousity that you feel in your chest. In a way, this is exactly what you were hoping for after all, when telling your lover to 'take care' of your guest...

"Uhnnn...!" You hear Rachel moaning softly again, followed by a very low "Yesss...!", that makes your boner press even harder against the inside of your pants. Whatever is going on in there it's not one-sided either, as you can soon make out what must be Katie's voice as well. "Mmmm, yeah...!"

"Oh god!" Your housemate suddenly announces, followed by a burst of giggles. You're still struggling to hear if they're saying something else, as they're not speaking much louder than they're moaning, though the next phrase is easy enough. "Damn, I've missed you Katie...!"

While the last statement fuels your envy, you can't really keep from smiling at the image of them being together once more. Most likely you'd have a lot more trouble letting them go like this if Rachel's ex was just a normal guy however...

The idea of Katie having a big cock like Rachel's makes the situation a little more confusing to you, but somehow you're mostly just excited about them getting it on with eachother. You also know that it would be wrong to sneak a peek at them though, or in any other way manage to disturb them, but you also find it difficult to just leave them alone without knowing for sure what they're actually up to...
