to RockyCandle0 :This is true. I had the great honor of pleasuring my mother in law, with the full knowledge of my wife, who was very pleased that was providing joy to her Mom.
to RockyCandle0 :I can attest to this. When my wife had her period and her mother was with us, I had coitus with the mother, with the full permission of my wife. As my mother in law put it at the time, "Everyone benefits and it is the healthy and reasonable thing to do!" “Měi gèrén dōu shòuyì, zhè shì jiànkāng hélǐ de shìqíng!”
