Sam thought to himself before saying "Let's get your arms and hands up with your other limbs, ok?"
You Nod your head as you focus on your arms and hands for another exciting round of changes. You feel your hand pop and crack as your digits grow longer, your nails darken before growing out long sharp points, and your claws. The skin around the palms of your hand start to thicken and puff out, taking on a leathery texture. It is your paw pads growing on the palms of your hands with smaller dots growing up to your fingertips. All too familiar brown hairs sprouting on the back of your hands, and steadily the odd hairs thicken into proper for as you subconsciously guide the growth down your arms and the changes to your arms.
You're a wererat, your kind is not known for your Strength like a werewolf, but still, there are some changes to your arms beside the fur. Muscles begin to stretch and grow as you maintain your breathing, feeling your joints adjust for longer limbs and shoulders broadening as you felt to all fours. The slow changes never made the stretching of tendons and expending of biceps more pleasant. Not helping that the fur was slowly turning off your sweat glands, forcing you to pant to try to cool off. at least you have enough will not to break sequence and change your face into a proper muzzle; also, your slowly swirling member isn't helping maintain your concentration.
Sam's eyes had Wondered from your arms to your lower body more than a few times. Your rat cock was slowly coming out of its shaft, and your large balls were begging for a release, but you had to put the brakes on the changes for now.
"We are nearly done my friend; now pose for me like one of them French rats." Sam jokes as you start showing off your mostly rat hair-covered body. Stretch out your arms and pose your hands each way that comes to mind.
A few more sketches and Sam was back to pondering...
"what should Sam have changed next?"
