Mother's best friend

My mother's best friend, Miyuki, has arrived at my house. Satoshi can't help but be bothered by the beautiful Miyuki that suddenly appears. He had a shameful fantasy and couldn't find an outlet for his frustrated feelings. He peers at Miyuki's changing clothes as he impulses, but is soon discovered. As Satoshi becomes slurpy, she smiles gently as he excuses that it's a misunderstanding... and does not hesitate to suck Satoshi's cock. He then whispers to Satoshi, who has his eyes shaking, "Please keep it secret from your mother."
