Good job, Rino! Your family will grow! Kokoro-hearted Rino and her father welcomed in a lewd duo, precocious brat Shota and perverted bastard Miyoshi, as foster parents! The two take advantage of Rino's kindness, wanting a little brother, and set their sights on her big breasts! They pretend to be ignorant and sleep next to her, insisting she's regressing, and then surprise her with their erect dicks! The virile brothers, who are already a pain to deal with on their own, attack Rino twice as hard! A brother-in-law cuckold story brought to you with double push!
