Around this time, some kids in the neighborhood started using her son as a pretext to visit the house of Madoka, an ordinary housewife who spends her days in peace. The bad kids were after Madoka's breasts, which were bigger than anyone else's!

One day, Madoka promises the bad boy that he will squeeze her boobs if he will protect her son at all costs, which she thinks is absolutely impossible.

At first, Madoka is simply uncomfortable, but she is shocked by the bad boy's powerful and skillful caresses, which are completely different from her father's normal, plain sex, and she unwillingly gets turned on.
