UGSS-013 - Mom gives you a soapland service: Yuna and Erika's steamy foam play

Yuna Takenouchi and Erika Hiramatsu each have a full-on soap play scene in the bath. They eventually take them off, but why make them wear swimsuits in the bath in the first place? The father who appears at the start is completely naked. If they were going to wear them anyway, I wish they had chosen something sexier—like a soft, skin-tight fabric. Also, since this is 'soap play' and not an actual soapland, I wish the actor playing the son had been more active instead of just being passive. It would have been nice to see some variety, like the son getting so excited that he goes rogue and takes the lead, driving his mother to climax.
