Her husband and brother-in-law give her a double penetration
At home she cannot be uncomfortable, much less dissatisfied. It is the objective of having a home, everything there should be security, tranquility and satisfaction. So it is normal for her to make use of anything that is inside, since she is the owner and mistress of the site. And the best part for her comes when her brother-in-law and her husband double penetrate her. She gives one guy a blowjob and then she craves the other guy. Since there is no problem because the husband is a cuckold and everything is between the family, then the incestuous threesome has happened very naturally.
