Pls help me find this yaoi manga

Pls help me I can't remember the mangaka or any portion of the title. I can remember that it's in an office setting. the superior seme has a relationship with his uke that is the typical cute funny type uke that doesn't know what to do type i think? then there is a scene where the superior had sex with his uke in the office but he was rewarding him and he rode him. that's right the superior seme can also become an uke! Then I remember that the superior has a officemate guy that is like seme looking because he used to be a seme but in his current relationship he is an uke. The lover of that officemate normally clashes with our superior seme. They have a separate manga story as well. Please help!
