Looking to use more of your favourite suction base dildos with your F-Machine? Now you can enjoy more fucking machine fun with the F-Machine USB Universal Suction Cup Base Adaptor. As you may already know, all F-Machines come with a Vac-u-Lock style adapter as standard which are compatible with the vast range of Doc Johnson Vac-u-Lock dildos and toys. What do you do if you want to enjoy hands free penetration with a non Doc Johnson sex toy? Well if your dildo has a flared base and/or a suction cup base now you can securely attach it to your F-Machine and breathe a whole new life into your dildo. The F-Machine Universal Suction Base (USB) is a revolutionary bolt on system which integrates your favourite suction (/flared) base sex toys with either your F-Machine Pro II or Gigolo. With this fantastic innovation from the pervy engineers at F-Machine, you can now choose which style of toy to use on your machine and discover new possibilities for sexual play & fantasy. The USB is designed to screw on the end of the thrusting rod and holds your dildo securely in place with the Velcro straps and o-rings. The USB will fit dildos with a suction cup base which measures up to 8.8cm in diameter. You have the option of holding your dildo in place with the suction cup, the o-rings or the Velcro straps (or any combination of these). You’ll receive a comprehensive O-ring set and four Velcro straps which should fit most dildo sizes. You can even pair the F-Machine USB with the Double Trouble or Rocky attachments.
