Yes, but things take a fortunate turn.

You stay near the cracked door, watching as Susie gets more passionate with fingering herself. You can see her hardened nipples underneath her tank top. Her skin begin to shine a little as her self pleasure begins to make her perspire. Judging from her quiet moans, which have become more frequent, and the way she rubs at something unseen between her legs, you would hazard a guess that she's getting close to climaxing.

Not wanting to be left out of the fun, you reach down and begin playing with your member through your clothes. You now realize that you've gotten fully erect from watching this lewd display. Before you can get too into it, however, you see that Susie has started looking your direction. Bizarrely though, she doesn't stop her movements, if anything, it looks like Susie is getting more into it. Not wanting to disappoint her, you adjust your position so that Susie can see you rubbing your bulge through the crack in the door.

Susie's eyes seemed locked onto your bulge, and it's only through the repeated asking of the voice from the phone that snaps Susie out of her daze. "Yeah? Yeah, that sounds amazing. I'm so close right now, you're gonna make me cum." Susie informs the other person, even as her eyes glance back at you, as if making sure you're still watching. Susie breaths heavily into the phone, before her body goes taut. Susie does her best to keep quiet, but you and the person on the phone can clearly hear Susie moan in orgasmic bliss. Not long after, Susie goes limp, leaning against the back of the toilet.

"That felt great, baby." Susie says. "Remind me to repay the favor after work." After exchanging air kisses with the phone person, Susie snaps it shut and begins to clean herself up. When she finishes up, she steps out of the bathroom and gives you a vicious look. "NOT.. A... WORD... TO ANYONE." Susie says in harsh whispers, not wanting to wake up Kris. You nod your head, to which Susie responds by leaving you alone in front of the bathroom, with the door wide open. While you don't actually have to go, you take the opportunity to get your hard-on under control. Once you are all done, you head back to your air mattress, trying not to wake Susie, who has already gone back to sleep.

You close your eyes once again, and try to get some sleep.
