Obviously

Melanie looked completely at a loss as she watched her brother and sister rut like mindless animals it was like she couldn't look away from the obscene transformation. Watching her brother go from a good-looking human to an amazing animal Adonis was already a shock but to see her sister already so transformed go from cat to wolf in a matter of minutes was an overwhelming experience. She watched her siblings closely, studying the intimate way that John moved his hands over his sister's 8 overstuffed teats giving each nipple a tweak with his long clawed fingers.

It was obscene she could see the bulge where John's knot held his cock inside the older girl. She felt the heat is rivulets of sweat rolled down her forehead and a tingle in her nether regions made it inevitable that she was going to be next.

Melanie swallowed hard, ever since she developed a crush on her older brother she'd been studying him in secret. Learning what turned him on. What was happening now was like something out of the phenomenal fantasies she'd found on his computer.

She placed her hand inside her waistband groaning and stroking herself. If this was like those stories then she would start to feel the changes soon. She wasn't disappointed.

The little blonde angel closed her eyes and the changes began to manifest first and sporadic places. The tips of her ears began to point and she could feel the sensation of sharp teeth against her tongue. She let out a little moan, giving her two recovering siblings a full view of her change from typical high schooler to blonde maned she wolf.

She felt a tickle in her nose as the tip became black swelling out and spreading white fur down the outside of her face. She let out a moan the fingers now tickling her love button harder she gave her brother a full show.

She spread her legs her skirt fluttering as the white and silver fur covered her entire body keeping her petite figure but adding a layer of musculature to it that suited her new predatory lifestyle. She let out a low moan that turned into a subtle whine as her face became more canine her irises swallowing up the outside of her eyes to form two gorgeous sapphire portals to her soul.

She bucked her hips upwards gasping and moaning as she felt a long gorgeous fluffy tail emerging from her rump almost knocking her over with sensation. Every time she bucked to pull a little less human girl.

She felt her chest swell, but nowhere near as big as Erica, and the tingle of six extra breasts soon pressed against her shirt lifting it up just enough to show off her navel.

With a sudden yip of pleasure Melanie the wolf girl felt her juices spilling over the floor and felt her brother's strong hands holding her tight.

John moved in close, making sure to lean in using his long fat tongue to kiss her. It was paradise.

Melanie spread her legs feeling the wicked claws on her brother's hand shredding her panties without a moment's hesitation. It was only natural after all she was never going to need them again.

The sinful siblings continued to kiss a little longer embracing their primal instincts until the tip of John's canine cock happily slid inside Melanie cementing her as the second member of his little pack.

The only question in Melanie's mind was if Erica was going to join them or if her first time with her Alpha was one on one.
