Yes, but things take an unfortunate 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. You quickly pull your hand away from your crotch and look away from the opening as you think of an excuse. You eventually settle on you wanted to use the bathroom and had only just arrived.

"...Yeah, alright. Just give me a sec." Susie says, hesitating for a few moments. You can tell from her tone of voice that she doesn't believe you, but she isn't calling you out on it. Regardless, your free show has come to an end, and you feel as though you have made Susie real upset with you.

After a few hushed whispers, and the sound of a phone snapping shut, you hear Susie wash her hands and step out of the bathroom. "All yours, 'pal.'" Susie says sarcastically. You go into the bathroom and pretend to go about your business to maintain your deception. 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.
