Gwen Diamond returns to fucking machines as sassy and confident as always. She strolls onto set thinking it's just a day of orgasms and fast fucking only find we have something far more intense in mind.... After she's bound and spread open, the machines are revved on high for the kind of fast, deep fucking that gets orgasms out of Gwen. We twist Gwen's love for suction and vibration into torturous teasing and even tickling by strapping tiny vibrators all over her tits and stomach, creating a creepy crawling spider effect. We also test out a new prototype suction machine that inflates and deflates the dildo. Though it still needs work, Gwen manages to have a nice little orgasm from the pulsing dick.
