Mera Eito's Manga List

Hiromi and Tomoya are trapped in a room with no escape unless they drink 100 bottles of aphrodisiac. What's more, they're bound by brutal conditions: they're forbidden from ejaculating for 60 minutes after finishing each drink. If they ejaculate before then, they're back to square one...
Can the two of them overcome the repeated effects of the drug and their relentless urges and find a way out? What awaits them at the end of this pleasure? Liberation, or inevitable doom?
