The woman kneels in front of the mechanical dildo that she has just turned on. The device thrusts back and forth, and she takes it into her mouth, sucking it deeply. She gags a bit as it hits the back of her throat, but she persists, taking it in and out of her mouth as she licks and sucks it with abandon. The dildo is slick and wet with her saliva, and she moans as she feels it slide in and out of her mouth. She slowly moves her head back and forth, taking more and more of the dildo into her mouth. She twists her head a bit and takes it in at an angle, causing it to hit her gag reflex again. She pulls back a bit and catches her breath before diving in again. Her lips are stretched tight around the toy, and she can feel it deep inside her throat.
