JKNK-141 - 50-year-old woman's fast piston-like action fluid masturbation

A housewife who cannot sleep due to excitement stimulates her clitoris herself every night. After everyone is asleep, the frustrated housewife pulls on her seemingly sensitive large nipples and moans. She swells her nipples tightly, and white pre-ejaculate overflows from a tightly filled vessel. She inserts two fingers deeply and quietly reaches orgasm while pre-ejaculate drips from her loose vaginal opening.
