She's interrupted

"What I want is..." Stephanie purrs, still stroking your cock. At that moment, Katie steps out of the bathroom, the noise of the door opening and then shutting is unmistakeable. Stephanie doesn't even bother trying to put your cock away, there's no way Katie didn't see it, hell, she's watching.

That makes your cock throb hard in your girlfriend's hand. Hard enough that it wasn't just a throb, it was a surge, and it's harder than it was before.

"Mmmmm....jealous," Katie purrs. You look over your shoulder in time to see her drop the towel. "This is where we are now. If you're giving Tom a hand job out in the open, I'm not bothering with clothes any more," she said, almost defiantly. She walked out and stood next to you, just behind you. She's close enough that you can feel the heat coming off her freshly-showered body, but just far enough away you can't feel the touch of her skin, but you can imagine her tits are just behind your arm.

"Seems like a good house rule," Stephanie says devilishly, looking at Katie behind you. No, she's not looking at her, she's eye-fucking her, and you can only imagine the effect it's having on Katie because it makes you want to cum where you stand.

"How about it?" she asks you. "No more clothes in this apartment?" Her stroking is slower and more deliberate now, and you can smell the two pussies starting to go into over drive. The fresh scent of your girlfriend's light perfume and your freshly-showered roommate are mingling with it, and you have never wanted anything more than to have Stephanie strip down, right fucking now.
