Strange dreams assail you as you sleep. Within the realm of sleeping, you walk into the forest with your girlfriend before she bites your neck and grins. You cry out in pain and begin to yell, but she offers gentle reassurance and pats your head.
"Shhhh... You're going to make a cute little pet and apprentice," she purrs as a fluffy set of wolf ears sprouts atop her head and a tail from behind.
You gasp in shock when a warm tingle envelops you. Primal arousal stirs in your loins, causing you to cry out in a heightened pitch. You break into a sweat as your insides swirl and your body shrinks. "W-- What are y-- you-- oooooh!" Your chest tightens, a pair of tits budding and rapidly growing. Simultaneously, your hips expand while your waist pulls inward. "Mmm-- ahhhh!" You moan as a ball of pressure forms below your navel, and your genitals writhe with bliss.
You barely notice as your testicles ascend with a 'pop' and your cock gradually recedes.
'Breed. Sex. Lust.'
A voice in your head sounds off as your tail and fluffy ears quickly grow, your hair falling past your shoulders as it becomes a silvery-gray color.
You realize you're becoming a wolf girl and reach down with a desperate cry as you probe the moist folds between your legs. As you do so, your clit finishes forming from the remnant of your penis. "Ahhhwoooo!" You shudder and moan as your tail swishes frantically. 'I-- I shouldn't be a girl! I-- I want-- to feel more... N-- No-- I can't.' You devolve into mental turmoil as your girlfriend smiles and closes the distance.

You suddenly awaken and sit up with a loud cry and gasp. "It was j-- just a d--," your eyes widen in horror as you hear your voice and look down to see a large pair of tits enclosed by a tightly-fitted tee-shirt. Your vulva pulses and tingles with pure longing. "N-- No! This-- this can't be real!" You squeal, putting your hands over your head as you feel the shape of your sensitive new ears.
Your girlfriend walks into the room with a grin. "What a good girl you are. Stand up for me, will you please?"
You feel an overwhelming urge to obey as your ears perk, and you stand to your feet. Your immediate reaction is to follow her command; if you do, she might praise you or pat your head.
"Very cute! You turned out beautifully. Why don't you lean over and press those gorgeous breasts between your arms? If you pose for me, I'll give you a treat."
Despite your internal protests and wounded pride, you can't repress the pang of excitement shooting through you. You shakily nod and lean over, posing for your precious master-- err, girlfriend. "I-- I don't-- I'm not-- I'm not a girl-- or a pet!" You stammer as your face turns beet red.
"Shhhh. Hush, now," your girlfriend cooes in response. "Be good, and I'll give you a tummy rub, okay? I might even touch that creamy thigh of yours," she promised.
You hate how wonderful this all sounds. At the same time, is it so bad? Would it be wrong to give in to these urges? You can only nod while tightly closing your eyes in shame. Any remaining shred of male pride could not override the instinctive need to explore your new, feminine attributes.
