"You want to do it with me, don't you?" Maoka, a serious businessman who doesn't express a lot of emotions on his face, finds solace in drinking coffee poured for him by the handsome barista at the coffee shop nearby, Botan. He stops by Botan's shop after work on his way home and is given a "love potion" by a lady he helped on the street.

Just like that, Botan kissed him deeply, took off his clothes, and was filling him with pleasure deep inside his body...!
