JUBE-013 If you bribe a professional student with a tight life, he turns into just a lewd livestock looking for a dick lol

I am a professional student and live alone. Living expenses, hobbies, and entertainment. I lightly agreed to a photo session because I didn't have enough money. I thought she was going to reject the old man's advances because he couldn't stand her young body anymore, but he ended up begging her for a kiss himself. Gradually, the demands escalate until creampie... It feels good, I get paid, and it's okay!
