An experiment who goes Wrong Chapter02 In progress ( Tassedar ) (Patreon)

“URHG!” Shizune growled gutturally, teeth gnashing as her expression blended both grimace and elation. Her abs popped out of her core and tightened, locking down into a meaty shield. She rolled around, letting Tsunade see her expanding back and inflating deltoids. Her fingers dug into the floor, tearing tiles and concrete as veins throbbed from the back of her hands all the way to her shoulders. Biceps the size of basketballs replaced her once-stick limbs, with immense triceps solidifying on the back of her arms. Crevices of great depth burrowed in between the slopes of her back muscles, this one expanding further and further. 

Her modest breasts were no more, large balloons of magnificent size exploded from her chest, flopping before they made contact with the cold hard floor, she groaned in delight as her painfully hard nipples rubbed against the surface.

In such a short time, Shizune had undergone the same metamorphosis Sakura must have gone through as well. Transforming her into a kunoichi of hulking build, supreme stature, and thickness, she stood up, letting a low moan as she did so. Her large hands trailed over her new body, cooing as she touched the muscle with sensual tenderness.
