I started attending a yoga class through my wife's introduction...
My gentle wife recommended it with a smile, saying, "The teacher is a really nice person," but now I'm rubbing my cock against the teacher's sweaty big tits, being seduced by her hot pussy through her yoga wear. "Keep this a secret from your wife..."
Every time Natsu Natsuki-sensei whispers sweetly in my ear and squeezes my erection with her thighs, my wife's face flashes through my mind, and guilt tightens my chest.
But that sense of immorality is irresistible. I can no longer resist the close-contact breeding lessons from the teacher, who is practically my wife's best friend.
Contrary to my feelings of apology toward my wife, I tremble with excitement as I cum deep inside her womb... The forbidden yoga sex life of the worst kind of husband.
