Ecchi wa Shuu-7 Kibou desu!

Sex toy producer employee, Aoi (a huge slut) keeps getting dumped by his boyfriends because he has a bottomless libido and asks for sex every day. One day, Aoi is drowning his sorrows with alcohol at a bar he frequents. He hopes to fulfil the desires of his broken heart through a dating site, but ends up falling asleep. He mistakenly thinks the waiter who comes to wake him, university student Iori, is the partner who matched with him and invites him to have sex. When Aoi wakes up, he is faced with the waiter from yesterday, a huge pile of used condoms, and a comfortable discomfort in his butthole... Is this the "non-stop cumming like crazy" experience he's always dreamed of?!
