His sister acts like nothing happened while he masturbates

Since he's been living with his stepsister, this guy is out of control. he can't go a week without shaking his shit. even today, while his sister bimbo worked, he got naked next to her and embarked on a masturbation phase. the girl will remain motionless for a while but she won't be able to watch him tickle her cock all day doing nothing. she decided to help him ejaculate.
