Ch6
Himbo gets a dildo that syncs with the dick of anyone that touches it. He finds his perfect dick at a bathhouse and "steals" it, not realizing he didn't turn off the sync completely and perfect dick guy felt every one of his masterbation sessions lol. Perfect dick guy figures out what's up and let's him keep the dildo in exchange for getting to see a live show. And then they fall in love lol.
Only a himbo of this caliber can accidentally stumble upon the perfect, gentle seme lol.
Ch6 ughhh involving unconsenting/uninformed people in your kinks (by way of exhibitionism) is gross
