Once again Sally and Amy find themselves fighting over the blue blur's hand. Sonic figured it would be pointless to get involved given how the two are stubborn as always. That was before kicking his shoes off though. After an extraordinary morning jog, his feet were quite exhausted. Just having his bare soles touch the floor was too much, they had become increasingly more sensitive today.

Seeing two problems around him, the clever hedgehog schemes an idea. The two girls would certainly do anything to prove themselves to the spiky hero, including a thorough worship of the speedster's feet. However, Sonic didn't actually intend to pick one over the other, he merely used their stubbornness to his own advantage. By the end of it, they would either catch on to his plan or become exhausted.

As a final joyful measurement, the cheeky boy decided to shrink both of them, to supposedly test their determination. In reality, it was solely for the purpose of his own pleasure, the cocky youngster would always feel exceptionally excited with ant-sized people near his stompers. Without delaying the inevitable, Sonic jumped on the nearest recliner and placed a single massive foot onto the table, giving the shrunken girls their cue to start.

The blue giant's foot was not just sweaty but also steaming up from all the heat that had been building up in his shoe. It was an incredible sight from the tiny girl's point of view. To them, it was an enormous blue doughy wall enveloped with intense warmth and steam popping right from it. The colossal hedgehog was so overwhelmed with joy that he couldn't even hold his foot still for a simple worship, he just had to tease his victims by flexing his gargantuan toes.

Both miniature girls had their own strategy to satisfy the arrogant titan. While Amy would climb around the gigantic sole to prove her flexibility to the blue blur, Sally would remain stationary in certain areas to intensely focus on them, showing her determination towards him. This was the unfortunate outcome of their little fight, the spiky boy they both admired had them fully domesticated at his foot. There is a lesson here to be learned, when two shrunken girls quarrel, the giant rejoices.
