Speculum training

She lies back and slides the thick dildo in first, slow and deep, letting it push her open until the shine of her own wetness coats every inch. When she pulls it free her cunt stays parted, already glistening. He watches, breathing hard, as she takes the speculum, spreads the lips with two fingers, and works the cold steel inside. A quick turn of the screw and the blades part, stretching her wider, wider still, until the whole pink tunnel is held open and he can see straight up to the tight ring of her cervix. She holds the position, breathing steady, pussy gaping around the metal. The moment is too much for him. He leans in, cock in hand, and shoots thick ropes straight into that exposed hole, painting the stretched walls and cervix with warm cum that pools inside her until it starts to drip down the metal frame.
