Zoe transforms into a futa

"UGHHHH" Zoe screams as the thick and busty futa grunts deeper into her tight ass.

Facing from the side you watch as Zoe's hips tremble and shake while getting railed from behind with the futa's tight hands on her ass. Between the thrust of the futa's cock and ballsack you see Zoe's cunt lips start to swell and purse outward.

"MOREEE" You can't believe Zoe is saying this as you continue to watch in horror at what happens next. Almost raising her off the bed, you watch as Zoe's tits swell to similar proportions of the futa. Her once modest B cup breasts were now heavy sacks pushed tightly against the bed as she held them together while face down in the sheets.

Spreading her hips legs even wider against the side of the bed you watch as your girlfriends cunt lips seal shut as two orange sized orbs swell outward slide downward against the slick ballsack of the futa cock still deep inside her. You see Zoe start to thrust at the bed as you notice her new 20 inch cock, sliding against the bed.

"Oh my god!" You gasp audibly as both of them turn to see you in the doorway. The large futa gives one massive thrust before pulling out and turning her sight directly at you. She rushes at you and you quickly move out of the doorway, tripping her out of the room and falling on her face. Her fat tits and balls collide with the floor outside as you slam the bedroom door shut and lock it.

You see Zoe, or what was once your girlfriend Zoe, laying right side up with her massive nipples pointed up towards the ceiling leaking as she squeezes them. You rush over to her side to see if there is anything you can do to save her or at least restrain her until they find a cure.

You hold her writhing hands back as her thick cock begins to harden between her newly widened hips and heavy swollen ballsack. "mmmmm" you hear her moan as her lips also swell, looking like thick cock sucking lips.

While you are still naked in your tube socks she pushes free from your grip and in one swift movement pushes you onto the bed before straddling you.

"Mmmm baby...." she moans again, while restraining your arms above your head while her heavy cock and balls rub up against your tense abdomen and chest.

"No babe! Stop!" you plead as she humps your body. You can't help but notice her new massive pair of tits hanging right over your face with her once soft nipples, now dark and hard while dripping milk across your neck.

Zoe pushes her wide hips and round ass backward trying to find the tip of your hardening cock to slide into her ass. Feeling your cock slide in, you feel the hot cum of your girlfriends futa attacker slide down your cock, tingling your whole body.

While Zoe restrains your hands you start to feel calm. Whats going on with me you think. "Am I infected??". You feel Zoe thrusting her ass against your cock as she recoils from your hands and squeezes her fat wobbling tits together, unleashing a stream of milk down her now heavy stomach and throbbing cock - still pressed against your stomach .

Grabbing one of her heavy tits you start sucking hard on her hard nipple. You swallow hard as sweet milk fills your mouth as the other tit covers your nipples and chest with it.

You feel your cock harden and your balls begin to swell and churn with even more cum. As you continue sucking, the futa outside finally manages to push through the doorway, reentering the room with ****, the futa eyes your cock deep in Zoe's hole.

Steeping closer and behind your straddling girlfriend, the futa slides her slick cum covered cock also inside of zoe's ass, pressing even tighter against your cock.

The futa, who's face you can now see quite clearly, has flowing blonde hair, bright blue eyes and a big grin with pouty lips to match your girlfriend. Zoe moans loudly as she feels the futa's heavy tits press against her back and squeezing zoe's large tits together in a kneading motion.

"mmmmm yeah baby, milk my fat tits. Fill me up with your hot cum!!". Zoe's tits wildly sway as they leak hot milk all over. You can feel the other futa's balls rubbing wildly against your own as your cocks compete for room in Zoe. You could even feel Zoe's hot orbs churning and pulsing with cum as they continued to swell with her cock against you .

You feel yourself starting to change....
