Serenity

Calling to my fellow readers here, I need help to find this one particular manga, the story was like... Mhmm

This is a story of a writer who did not experience on having sex, yet one day he decided to have a service massage at home, like ano.. he search for a website then he saw a website that is open near his address, then out of tiredness he just entered and ordered one(?)

Now knowing it was a dirty website... Because the logo was half covered in his sticky note

Plss if someone understands my horrible english

Can anyone give me the title
