Enjoy Ruby being embarrassed as the girls tease him about his lack of size, though from the look on her face I doubt Aria believes it's just shrinkage…
Gotta love the little details, how when Ruby walks out of the bathroom Aria instantly looks at his dick, before stares him right in the face, while Sonata just takes in his body in surprise before eyeing the goods with a giggle… I love little character bits like that ~
