FULL RES POSTED ON DISCORD
“All set,” Yuki said, giving Miko’s behind a swat.
Yuki rose to her feet and gracefully walked over to one of the golden gas cylinders lined up on the edge of the platform.
“Here it comes~” Yuna said looking back at Miko. With a turn of the valve, the rush of lighter-than-air gas surged through the hose with a metallic hiss.
Miko’s belly began to swell almost immediately. Her soft, toned stomach rose visibly, rounding out like a balloon. A warm, stretching sensation spread through her midsection as Miko let out a muffled hum of delight from behind her safety valve ball gag. Her belly continued to grow larger, smoother, and tighter. The gas continued to fill her and the tension in her stomach radiated outward.
Her breast followed, expanding as well with the gas building pressure inside her. At the same time, Her limbs began to thicken visibly, their slender shapes rounding out as the pressure increased.
Yuna took the opportunity, stepping forward to begin tying the red shibari rope restraints around Miko before she grew too large. Yuna looped the rope around Miko’s neck making sure not to catch any of her hair underneath the knots. In a rhythm matched to the rate that Miko was expanding, Yuna began knotting and routing the ropes around her while Yuki continued to monitor the gas flow from the cylinder’s valve.
