I forgot what it was called. The manga was ecchi with erotic scenes, but was slice of life about a guy who just joined a company (selling products i believe) hooks up with a superior female. They do hotel meetings during work, etc, etc. I don't remember too many details about it, but it reminded me of futari ecchi, haru yo koi, along those lines. It had nice romance, kinda harem, and the last chpt i remember is that they get a new neighbor who is quite erotic and has the hots for the guy and does stuff to him while his gf is preparing tea. Not sure if that helps much >.<. Also, the manga begins with the guy having not a particular job, but he worked part time as a mover. he helps move the stuff for a woman, and they break a bottle of wine, so they drink it their and have sex. Then that woman ends up dating him.
