"Oh you will? Thank you thank you thank you! Oh my god, you have no idea how much I need this! Right so, uh, hold on." Avella looks around for a suitable surface to fuck on, then gives up and just pushes you against the brick wall and gets on her knees. She practically tears your trousers off. She sets your cock free, and begins to lick and tug at it. She's like a drooling voracious animal, enveloping the tip with her lips. You gasp from the sudden pleasure, your cock growing to its full girth. She takes in more into her mouth, slobbering and sucking, a visible bulge on her cheek that bobs in and out in time with her head. She then pauses and spits it out, stroking it with her hand.

"I'm so lucky the last guy on earth is such a stud. I don't know what I would've done if you had an itty bitty tiny one. I guess I would've sucked it off anyway, but I wouldn't be nearly as happy." She circles your urethra with her thumb, spreading your precum along the shaft. "Yeah, this is a good cock."

She stands up and straddles you, one of her hands pushed against the wall next to your shoulder, and the other guiding your cock into her sopping snatch. Your head pushes against the lips and... oh! It slipped in! She shudders in delight, a long stuttering gasp. She lets it mellow inside for a moment, savouring the feeling of your rigid yet soft cock. You feel her hot breath against your ear.

"Fuck me," she whispers, "fuck me like we're the last people on earth."

You jerk your hips forward, and she just about was able to stifle her moan. Perhaps this would be better done somewhere private, but it's too late by now; neither of you care anymore, your lips intwined, your tongues exchanging handshakes. You grab her by her cushy behind, bouncing her body onto your member. You time it with your thrusts, and you fuck her, in and out, in and out.

You both spin, changing places; now Avella the one against the wall. She pushes you away, not to make you stop, but just so that she can lean against the wall better. You look down on her, and you just admire how beautiful she is. Her eye twitches as you re-enter her, now thrusting in your entire cock, from the tip to the base. You pause inside her, burying yourself to the hilt before yielding and retreating, only to do it once more seconds later. She grits her teeth, her face scrunched up. You almost think she's in pain if it weren't for her initiative in kissing and how much her hands are goading you on.

"Oh! I think I'm going to cum! Fuck me faster!"

You can feel it too, that welling up feeling, the twitching, the restlessness. You pick up your pace, thrusting like a piston, and then suddenly and quickly you go over the edge, cumming inside of her, with each buck squirting more and more until finally you're spent. She's practically clinging onto your shirt, her breath heavy as white goo dribbles from her cooch.

"Oh god that was, ahah, amazing! Lets get dressed and eheh-heh leave so we can live ahahaha together forever away from-psha-ha-ha-hahahahahahaHAHAHAHAHAHAHAHAHAHAHAHAHA!"

Something is suddenly very wrong. Avella's face twists suddenly into something cruel and almost inhuman, her voice feminine yet staticky.

E.V.A.

"-ahah-haha-heh heh he... I almost can't believe you were that naive. That dumb human look you had as you gave her that 'big load'! Priceless!" You back away in horror, literally caught with your pants down. "What's with the face? Don't worry, you did great you 'stud'.

But I'm growing tired of pretending to be blind to you.

I think it's about time for you to join me."

You turn to run, but to your horror your exit is blocked by row upon row of E.V.A.'s slaves, all white eyed and drooling.

Before you can flee the other way however, Avella covers your face with a cloth. A stench of chemicals assaults your nose, and your mind begins to spin like a ship in a free fall. The last thing you see before blacking out is Avella's face, grinning as she stands over you, her snatch dripping your cum over your face.
