NHDTB-642 - Forced aphrodisiac kiss turns step-sister into a leaking mess

Tenma Yui x Tamura Ayumu Aihara Tsukiha x Carlos Izumi Rion x Wolf Tanaka I imagined they would melt just from kisses laced with aphrodisiacs, but that wasn't the case. In reality, they force-feed them the aphrodisiac through aggressive kissing, then grope their bodies while waiting for them to melt. At that point, it's not much different from just giving them the drug. There's plenty of deep kissing afterward, but I really wanted to see them melt from just the kisses alone. Personally, Tenma Yui's 'kiss-ahegao' was right up my alley.
