A message from Sara.

The ping of a message popping up gave you a start, but you were pretty sure none of it showed on the surface. Letting go of your cock you leaned forward to respond to Sara's good morning message, and reminder that she'd be driving over today. Almost an hour and a half with no traffic, the drive would take longer in the afternoon, when she would be setting off.

As you both type about meeting your family and Sara and Charlie getting to see each other again, for the first time since last winter or even farther back if you remembered right, you're hearing the noise of Michael's hand pumping his dick three feet from you. Remembering your own masturbation, you resume.

You tell Sara that you're typing one handed, and though she responds with characteristic support, this isn't the biggest deal in the world for her. Until you send a message letting her know that you and your brother are doing it at the same time right now.

There is, for a long while, just the three dots fading in and out.

Then a video appears, and finishes loading. It is captioned: "Show Michael, too."

Would that really be a good idea? It was hard to tell with this much sex in your head right now. There was an urge to do it, to thrill at the exhibition of your girlfriend, but a strongly ingrained resistance to getting his attention right now.

After what felt an age, the comforting thought that if you could trust anyone not to be wierd or disrespectful about this or Sara, it would be Michael, tipped the balance.

"Hey," You say, tapping him nonchalantly on the elbow without looking and gesturing at your screen, where you'd just started the clip, "watch this with me for a minute." You said it like a half comitted suggestion, but you felt Michael turn his head out of curiosity, at least.

"What is it?" His voice had a tinge of excitement in the heat of this moment.

"I don't know yet." You respond with an audible smile as the video shows a girl's body as she stands naked in her bedroom.

"She's fit!" Said Michael as he changed from stroking his dick to pumping it.

You just nod as Sara, holding the phone so her face is never visible to Michael, spins around -giving you a view of a large, dark stain on her floor- and flits out of the safety of her bedroom, roaming around a seemingly empty house while flashing the camera her pussy and arsehole at every opportunity.

She arrived back at the bottom of the stairs after a circuit of the lower rooms, sitting on the second step in the hall and spreading her legs.

She started to slowly rub her pussy, spreading her lips and finding her clit, before letting out a long, steady, clear stream of pee.

Her peeing and fingering session went on long enough for you and Michael to both cum, almost two minutes in total since the video started.

Sara's next two messages had pinged while you both watched, and leaving your cum fountain to dry on your chest, you silently read requests from her for reviews.

"Who was she?" Michael pried, hope evident in his voice for perhaps more of this girl, or a way to find this again himself.
