You think you're about to get a blowjob, but Luna instead of sucking starts... blowing air into your cock! You hear the sound of air slowly entering your body from your urethra, then getting stuck in your testicles. You move into the bedroom and start to feel strange. Luna continues to blow air into your cock, puffing up her cheeks until you both notice your testicles, now inhumanly large, popping up on either side of your cock and her face. Luna laughs at you and your gigantic balls but she has no intention of stopping: she wants to make you reach your limit. She therefore continues to blow into your cock, until your balls are so big that she can no longer reach it with her mouth. She then starts blowing at a distance, hoping to still get enough air in to make you explode: and she succeeds! A loud double explosion, your balls exploding one after the other!
