DVAJ-686 I’m a shy guy who gets made to keep watch for a delinquent couple at school, but I’ve been secretly invited afterward by a girl who isn’t satisfied with her quick-to-finish boyfriend, and I’ve been enjoying a fulfilling life as his stand-in partner. Kurumi Sakura

A shy, bullied virgin is forced to keep watch by a delinquent couple using the school as a secret hookup spot. Unable to resist, he peeks in and makes eye contact with the girl. He thinks he’s been caught, but after they’re done, she calls him over and says, You were peeking earlier, weren’t you? Show me yours too. What follows is an unexpected turn of events. It seems she’s dissatisfied with her boyfriend’s lack of skill and is very curious about the boy’s obvious arousal. Swept along by the moment, they end up getting together and discover amazing chemistry, leaving her completely hooked by the intense experience. From then on, after each time he is made to stand guard, a secret extra meeting begins.
