In this French gonzo classic, Eva Sin, a mature blonde educator, schools her husband, Olivier Lecoeur, in the art of cuckolding. As she strips and fondles herself, he watches, his cock tenting his pants. Eva's lesson begins with a strapon demonstration, but it's soon replaced by her student's eager cock. She rides him, her tits bouncing, as Olivier looks on, helpless. The lesson concludes with Eva's tits glistening with her student's cum, a testament to her cuckolding expertise.
