" I see we got a little CFNM thing going on today" Diane says and both laugh as Diane grabs his testicles and gives a hardy squeeze. Billy slightly bends at the waist " oymph!" She then kisses her son on the lips and inserts her tongue while at the same time zaps him with her knee THWAK!" ohwhowhooo" Billy grabs his sore balls and does a little dance before he resumes making out with Diane as they slowly go to Diane's bedroom.Diane sits on the bed and tells Billy to "spread em" as he does she kicks him Thwink! " oof" she leaves her foot in his,groin as he unbuckles her ankle strap and takes her sandal off and kisses her foot as they repeat the routine with her other foot Diane unbuttons her jeans and slides them and her panties off ,she then takes off her shirt she is not wearing a bra. She spreads her legs and Billy mounts her inserting his seven inch penis in and out as his mother moanshe stops pulling out of her as he gets on his knees and puts his tongue in Diane's neatly trimmed black haired vagina after she climaxes he inserts his cock back inside her and rhythmically moving his hips ever so faster.
