A young brunette visits a therapist for a relaxing session on the massage
table. The masseuse turns out to be an elderly woman approaching sixty
years old. Without delay, the horny senior gives the girl an intense vaginal
workout: poking, pulling, rubbing, fingering and prodding the girl’s cunt
leaving her squirming in delight. 
See "Girl examines an old woman's cunt" for the sequel.
