While they relaxed on the bench, every one of the women slowly started to get aroused. They could'nt pinpoint what caused the arousal, but while they where sitting put, a eerie fire started to burn between their tights. They don't even cared about it, as it washed away their human emotions soon after it started to wet their pussies.
They all fell silent after a while, leaning back on the bench, feeling their lust and desire take over their minds.
Allison soon unbuttoned her fly and started to massage her wet pussy with trembling fingers.
Maddie soon joined the show, pushing two fingers deep inside her dripping hole and stroking her clit like mad.
Aroused, Kristie and Lauren started to kiss each other. They never were into lesbianism, but the need to feel and taste each others lips and bodies grew too intense. Soon, Kristie shed Lauren's blouse and bra, starting to kiss her moaning friends hardening nipples.
Something happened to them, but no one of the women could tell what or why. They all got carried away by the incredible lust that now even seemed to irritate their skin.
Not noticing that fur slowly started to grow on their bodies, the women started to moan and whine and one after another started to shed their clothes while they grew bushy tails.
Strangely, no passerby seemed to notice the strange change that transformed the women into dog bitches, everyone was just passing by, no one took a look at the moaning, panting and shivering girls.
Kristie was the first of them to feel her bones shift and change, as her body took the appearance of a black shepard bitch.
Lauren was the first of them to feel her tits multiply and her face push out into a muzzle.
But everyone of them felt their sudden need to be fucked by a dog's slick cock enhanced incredibly and soon they stood beside the bench on paws instead of feet, four perfectly transformed dog bitches in heat.
