Noises in the night

I wake up in the middle of the night. Slowly coming to my senses trying to remember where I am. It's dark but I feel Megan pressed up beside me on Kate's small bed. I slowly become aware that there is light and sound coming from the other bed. I can hear my cousin Sara talking and see the light from her phone. She seems to be moving around a lot. I'm trying to figure out what she's doing when I hear a snippet of what she's whispering into the phone."..so wet..". Oh my god I've woken up to my cute innocent cousin masturbating. I realize the movement is her hand moving by her crotch.

Now that I know what I'm listening to, I begin to pick up more details. ".. Horny.. miss you so much... I'm even thinking about relatives, I'm so horny... Can't wait to see you tomorrow night..."

Now Sara's tone of voice switches from a throaty whisper to a higher pitched note of surprise,"What?..I can't do that they're in the room... Well I know but they can't see anything more.. well I think you will like them, but what does that... Oh okay if that's the deal."

I don't really know what Sara us talking about but she moves her phone away from her face and pulls the covers off her body. From the light of the screen I can make out the length of Sara's trim body. She's wearing an old thin white tank top that does nothing to hide the hard nipples on each of her breasts. On her lower half she's naked I can see most of her toned smooth legs. In this light, at this angle I can't quite make out the details of her sex, but that quickly changes as Sara brings the phone and apparently front facing camera directly in front of her smoothly shaved pussy. I move my hand to my crotch and begin to slowly rub.

"OK , now show me yours." Sara says as she begins to rub a couple of fingers from her other hand over her clit. "Oh yeah, there you are." I can see Sara slide her fingers down into her vagina. "I'm imagining it's you inside of me right now...EEE...Oh.. EEE..Oh " Sara is picking up her pace now. I can hear the squelching sounds of her fingers working in and out of her cunt. "Oh... Dan..EEE..Oh...Dan ..EEE." What's this? Is her boyfriend named Dan, is she saying my name? Regardless this had me very aroused now. My hand is now stroking my fully hard cock with some ****.
