Blow, and I will submit~

Kevin, a tomb raider who travels abandoned planets, finds an old flute on the uninhabited planet P7713. "What are you?" "The flute, of course. The one you just blew." The very flute he mindlessly brought to his lips transforms into a man, Noah, who immediately begins tempting Kevin to consume him. "You blew the top hole, and I became like this..." "........." "To reverse it, you'll need to blow the bottom hole, won't you?" Noah, the former flute, smiles beautifully while gently stroking Kevin's arm. "Aren't you getting frustrated? Just take off your clothes and let's get on with it. You're so hard." "I'm not hard." "......Huh?" "It's not standing up." ...But then, why is he so massive?! “Suck properly. If you don't make me climax, I'll snap your spine and throw you into space.”
