My naughty son gf

[Lion111]

Rosie is a 50-year-old woman, when her son brings home a new girlfriend named Alina Rosie does not like her. Her son's new girlfriend has a perfect body but her boobs are less than perfect, she is also overconfident and disrespectful to Rosie. A few days at Rosie's house and the two women do not get along, one morning Rosie decides that she must put an end to it and she must throw Alina out of the house. Rosie's son is not found and she can take out her maternal authority and demand that this sexy woman leave. What ended up happening was that Rosie found herself licking Alina's pussy and her boobs. Alina just laughed the whole time and teased Rosie. Rosie found herself a straight woman who fell for her son's girlfriend.

Ok, the pivotal moment of the story is the bit you left out. How does Alina turn it around so that Rosie's maternal authority crumbles and she falls for Alina?
For me to enjoy the story, this must be somewhat plausible.
