I feel like the common thread among the girls I've liked (though I don't have much romantic experience) is that I tended to love them for their personality rather than their looks. However, my current girlfriend's little sister is the cutest woman I've ever encountered in my life, and it's a real problem. This is because her sister keeps secretly seducing me... but even though I want to avoid this situation, she's just so incredibly cute... I feel like I'm going to lose it, completely forgetting about my own girlfriend... Rikka-chan, the sister, approaches me with the theory that a handjob isn't actually cheating. While feeling guilty toward my girlfriend, I'm drained by Rikka-chan's handjobs—I'm the worst, but it's also the absolute best feeling in the world...
