Some suspicious movements

Erica's peacefully napping on my couch, face buried in the pillows, ass still turned to the camera. She was so tired she didn't even complain about the lights.

God, I love a skinny girl. Look at that thigh gap... - Zooming in some more, I focus the camera directly on Erica's ass. Her cheeks are so perky they don't sag when she's sleeping on her side. I start stroking my worn-out cock once again, I can't help it.

I'm feeling pretty drained myself, so I take one final peek before getting back to work. But as I lean in to soak in all that hotness, I see some strange movement between Erica's thighs.

"What's that?" - I ask out loud, trying to zoom further in, but I've maxed out. So I keep staring at my screen, noticing ever slightly changes in the frames. It's kinda blurry and a bit pixelated. - "Fuck you Bill Gates." - I curse, amusing myself. But whenever I see something, it's always in between her thighs... right where things get interesting.

But no matter what I do, I can't get a clearer view. So I decide to see for myself. Holding my breath, I try to get out of bed as quietly as possible. Luckily my door is half-closed, so most noise is probably a bit muffled. I start tip-toeing through the hallway, slowly and breathing as lightly as I possible can. The house is quiet and even the TV has gone into power saving mode. So I take my time, one foot in front of the other until I reach the doorway leading to the living room. I start to hear something, or so I think. I can't quite make out what it is, so I soldier on towards the couch.

Erica's head facing the entrance and I'm walking from behind. I know there's no risk of getting spotted, it's only sounds I gotta worry about. A few more deadly silent steps and I'm almost at the couch. I stop for a second and I can finally make out what I was hearing. Erica's mouth is glued to a pillow and it sounds just like muffled moans. Her eyes seem closed, so I go in further, close enough to cast a shadow on top of her body. I lean in to have a better look at that young pussy when I finally see it! The source of all mystery. It turns out the girl is shamelessly playing her pussy accordion on my couch. She didn't even bother covering herself!

Heh, so much for good girl... not only did she not ask to dress herself back, but she's also comfortable enough to masturbate right on top of my couch by herself. It's brand new, too! Lucky for her, I can think of no better way to smear it than with teenage pussy juice...

Erica had gone from innocent-virgin-with-no-boyfriend to cock-sucking-cum-swallower in a matter of days. And there she was now, surreptitiously trying to get off in my living room, surely still worked up by everything that had happened that night. And despite the aching balls and the sore cock, I see it coming to life again. I was very tired by then, but Erica must have been exhausted after all that drinking, because she didn't even react when I lost balance, stepping a little harder on the wooden floor and causing a stomp. Her obliviousness gives me confidence enough to lean further in, mere inches from that ass. I can now hear the rhythmic squishy sounds of pussy juice that her fingers are creating. It's a beautiful melody...
