Richard did deserve the revenge but being a fungus he would never know what had happened to him.
You aim the watch at Richard and suddenly he is transported to a vacant field. There he begins to grow and grow and grow. He feels a weight as if he were getting fat but it wasn't fat that he was putting on it was stone. He was becoming a frat house. His mouth became the front door and his ass became the back door. The occupants, deliveries and most activity happened at the back door. His eyes became windows allowing him to see everything that was happening and he was able to feel every activity that happened inside of him.
Now Kevin wasn't totally blameless in the situation but you do give him the body of a god. The god Bacchus. You wanted him to have an incredibly enjoyable life bowing to his lustful feelings and making him the image of Bacchus did just that. And he already had gay leanings but you pushed it a bit further and made him fully gay and with his godly lust and partying the house became a party house. But it was the first gay party house at the university and it was popular.
Richard felt every sex act inside of him. It was like it was being enacted upon him. He felt Kevin's heavy footfalls trodding though the house pulling twink or muscle boy or chub into his chambers showing them acts of love only dreamt of in cheap kinky porn novels.
Richard was getting a lesson.
