It was a mistake to teach my cousin Ichika, who seemed to know Ichika, how to give a blowjob. Since then, she has been sneaking around her parents' eyes and showing me how to give an air blowjob. After she saw it and realized I had an erection, it escalated even more. That erotic tongue movement, the way she strokes... even though it was air, it was too erotic! It was only a matter of time before I crossed the line with Ichika, and I spent my days tormented by regret. But Ichika blowjob feels so good I can't believe I'd only just taught her, and her pussy feels even better, so I can't stop!!
