What a fucking machine is for - Extra strong sexual experiences
The powerful sex machine will fuck you hard in several positions that you can quickly set. These are quite intense sensations that you won't experience with manual insertion or fucking with a partner.
The intensity of the fucking lies in the strength, the size of the dildos, the regulation of the fucking speed by remote control and also in the spell of the unexpected. For example, with a large dildo, where the body puts more resistance, the sex machine will pull you back with the dildo and then impale you. Or the machine with a Vac-u-lock adapter and a dildo without balls will guide the whole dildo inside and then pull the dildo out and open you up nicely. A weak fucking machine under 100w can't do that.
You don't have to annoy your partner or have the sex machine as a "third" to the couple and thus enhance the shared experience.
Fucking with a remote control machine will enhance submissiveness and dominance. You are just a thing that is being fucked by a machine and not worthy of human touch. For the dominant person, the sex machine frees your hands for punishment or other actions.
