I’m looking for a manhwa-

my friend was like “you should read this” and I asked for the name but she said she forgot. She told me theres a guy who has a tip as big as a mushroom. She told me it started off with a girl who hasn’t had sex in a long time and is desperate. I think she said the girl was delivering a package and saw the guy in bed and I guess they did it. Pfft- it sounds kind of funny. I think she said that lots of girls end up having sex with him.... that’s all she told me. If you do know please do tell ┗( T﹏T )┛
