Give them some 'balls' to play with

You stand on a crossroad. On the one hand, you could leave, and retain your humanity. On the other, you could take advantage of two petite, athletic, sexy girls. They are infected, sure, but honestly, all things considered, is this such a bad way to go? No, this ain't a bad way to go at all.

While they seemed to not care much about your presence before, now that you've removed your trousers they can't keep their eyes off you. You slap and grab you ball-sack, telling them out loud that you've got a couple balls for them to play with. If you're going to go out, you might as well go out with a bang and a joke.

It doesn't take long for the nearest one to reach you and fall to her knees, though you push her head away until the other one arrives as well. Eventually she does, though she nearly got tangled in the netting that spans the court. Seeing them sitting there side by side, their grey skin glistening with sweat, their ochre eyes eager to begin... they almost look cute, and it spurs you on, making your cock hard and yearn-full for a wet hole to fuck, and further reassuring you that you really, actually want this. Yeah, you want this. You grab the shoeless infected by her chin, opening her mouth with your thumb and guiding it to your ball-sack. She sniffs it like an animal, before giving your sack a tug with her lips. It's not long before she's sucking, and kissing, and licking at it oh so eagerly. The other one tries to butt in on the action, but the shoeless infected pushes her away. Your cock and balls are hers, and she makes sure she knows that with a growl. The other one, disappointed that she won't experience your manhood (at least not right now), is otherwise undaunted. She crawls behind you, sitting on her knees so that her face is in your ass. You feel her tongue tickling your anus as she spreads you ass cheeks apart. It's all very unexpected and sudden, but not entirely unwelcome. You feel her hot breath against your sensitive skin, giving you goosebumps. You almost yelp as her tongue licks at your perianal area. You twitch and shudder, and you just can't take it anymore; you grab the shoeless infected by the sides of her head, and impale it on your shaft. Her eyes are full of surprise, but they slowly melt and roll back as you begin to rapidly throatfuck her.

"Mmpff!" she moans.

"Mnach-mnach-mnach..." the second one moans in reply. She continues to happily eat out your asshole, her tongue worming in like a peg into a slot.

Your hips thrust like a madman, your legs shaking as you're practically fucking her brains out. She can barely hold herself up; the only support she has are her arms tightly wound around your thighs. Her throat is like nothing you've ever felt before; so hot as to be burning, so moist as if it were lubed, and so tight as well! All that, combined with your vigerous cock movemements, adds up to an over abundance of stimuli, and you cum. Oh yes you cum! With one last buck and a tightening of your grip on her head, you freeze with your hips forward, sending rope after rope of you seed down her throat and into her bloating belly. At that moment, it's as if your brain stopped working, not only from the otherworldly euphoria you were experiencing, but also because you are no longer 'you'. You are one of them now. Fangs jut menacingly from your mouth. Your skin is a soot gray, and covered with sores. Your cock twitches with reinvigoration and unholy seed.

The infected impaled on your cock slides off with a serene but completely mindless look on her face, your cum drooling from between her lips. She falls to the ground, bathed in an afterglow, her belly full but not nearly satisfied. After a short rest, she'll be ready for round two. But in the meantime...

You turn around and grin your fangs at the other infected. She grins back. Her eyes are full of longing to be used just as her partner was, and you're very eager to see that request fulfilled.
