LULU-391 While my husband was on a business trip, I unknowingly teased my perverted father-in-law with my sweaty armpits and made him hard. He then licked my armpit and immediately penetrated me. I made that relentless dick cum by trapping it in my armpit

I've been living with my son and his wife for several years now, sharing a home with the busy son and his wife's enormous breasts that were hard to look away from. I couldn't stare at my daughter-in-law's huge tits lecherously, so I suppressed my restless feelings and continued living like this. One day, my son had to go on a business trip, leaving me alone with my daughter-in-law for several days. While cleaning, I got excited seeing my wife's defenseless armpit peeking out from her sleeveless shirt and couldn't help but bury my face in it. My wife was confused, but the smell of her sweaty armpit made me hard, so I licked it all over. I got carried away and immediately had sex with her, but she made me ejaculate by squeezing my armpits… Since that day, the pleasure of ejaculating while being squeezed in the armpit has been unforgettable and I've become deeply hooked on the armpit hair swamp.
