[Makin] Boy trained by friend's Sister

A nervous boy's afternoon visit to his friend's house turns into obedience training when her smirking futanari little sister snaps a collar and leash on him, rewarding every woof with head pats and a beaded tail plug while cooing 'good boy.' When she finally bares her enormous cock beside his caged 'cute little one,' the size comparison is only the beginning—his mouth fails inspection, and she decides his virginity won't survive much longer. Sent home still plugged beneath his clothes with a promise to 'play again' tomorrow, he slips out just as his friend returns with dinner, wondering where Jun-kun went.
