Perhaps you never heard of the First Amendment to the US Constitiution which gives me the right to say anything that is legal. So go pedal your fucking papers somewhere else or just move to Russia where they don't have any freedom.
This kind of sexual affair intrigues me greatly because it signifies that sexual lust is not confined to any specific class of lover or marital status. The woman having sex is a mature wife and mother of another woman who is married to the man who has his cock in her pussy and is giving her his cum load. Consummating a sexual relationship of this type is certainly a way to unite family members in a secret manner and also a good exercise to provide an addition to the family.
I used to fuck my mother in law every Saturday night all summer around 1985 in the car, she always wore a light cotton skirt which was quite see through and suspenders and stockings. She always wanted my spunk inside her cunt, then I'd drop her home, don't know if her husband got sloppy 2nds....
Your MIL is very sexy, and you knew just how to excite her with your hand on her tits, belly, and pussy. Then, after you came in her pussy and gave her an orgasm, you gave her another one by massaging her clit. No wonder she enjoys having sex with you.
