Liam's cock was now clearly porcine in nature, a wild boar he explains, as you smell the musk coming from it you collapse to your knees, juices flowing down your legs. You are at Liam's mercy, soon to be a girl no more.
Clearly having trouble containing himself Liam roughly shoves you forward onto all fours and walks behind you. He lowers himself and places his arms on either side of you, his huge bestial penis raring to go, wasting no time he plunges in, you gasp and the changes begin.
As Liam plows away at you your pleasure slowly grows as you begin to morph. First your stomach begins to bulge, your torso lengthening and fattening as it does. Coarse brown hairs are beginning to grow all over your body.
Next your arms and legs twist, shaking you look down as you see them reform into legs. Your fingers and toes grow stiff and in short order turn into trotters before your eyes. You feel your gums push aside as two tusks burst out of your mouth and come into view, drool dripping from your mouth as your teeth become gnarled and bestial.
A new surge of pleasure elicits a squeal from your mouth as your once petit ass swells with fat, eat cheek ballooning out and pushing against Liams stomach. As his balls slap against your new behind you release a spray of juices as your vagina pulsates and begins to change. Your once tight, pink lips darkening and growing thick and leathery. You're asshole is not far behind and you moan as it swells into a dark donut nestled between your cheeks, a curly tail sprouting from above it.
Spurred on by your now much more compatible sow pussy Liam grunts and his cock begins to pulsate, ejecting thick ropes of boar semen within you. You think you cannot be more in pleasure but are swifting proven wrong as tingles of pleasure run down your body and teats sprout all down your length, your original breasts pulsating and changing to match. As soon as your teats finish forming they bloat with milk, droplets forming on the tip of each nipple.
As your stomach further distends with the impossible volumes of cum Liam is pumping into you let out a drawn out squeal as your face pulls forwards, your nostril trippling in size, as the last of your fur grows in, your ears enlarge and flatten, completing your transformation.
Panting Liam lays atop you, it will be hours before his penis shrinks and returns to human, allowing him to end his mating with you. But you don't care, though you are still you, you are also a fat sow, and you love being bred.
