Walked into his friend's house with the enthusiastic reception of the sisters, a house with girls dressed sexy, comfortable, carefree as if there were no guests in the house. Maybe they just treat you like a little brother, they don't care much.

Then when you accidentally see one of his friend's sisters masturbating, and you get caught masturbating, you become good prey for her to satisfy, with a big cock, good fucking ability, so in the days that followed, he became a sex machine neck for girls.
