"B-B-B-B-B-Bu-" Her meager protest was cut short as her mother ripped off her blanket and began to stroke her erect, sensitive cock, causing Mary to let out a series of light moans. Any other form of protest was put to a halt as Yuka mentioned possibly being upset. Over her life she had learned never to make her mother upset. A dark spot soon was starting to form on her straining, purple pajama bottoms as pre-cum started to leak out the tip of her cock.
