The girls ask to see his dick

Noriko naughtily whispers 'Show us your dick Ryu-kun! I want to see how you compare to your dad!' Ryu flushes red at her suggestion.

Mayu agrees with Noriko 'Yes I'm curious too. Show us your dick so we can tell whose dick is bigger! You or Takaya-sama?'

Ryu still feels reluctant but Sara persuades him 'Don't be shy Ryu-kun! We are your stepmothers so its ok for us to see your chin chin!'

Noriko guilt trips him 'Sara gave you a backrub like you asked. You should make it up to her by letting us see your dick!'

'Alright' Ryu feels very embarrassed but also very excited he takes off his swimming trunks revealing his dick to stepmoms for their rating??
