Take you pick from our collection in the link below, the Reciprocation Actuator was bought 2 weeks ago, it came with a vaculock attachment to screw on the end of the shaft, so i drilled a hole in the end of our 9" SilexD dual density thermo reactive dildo to test drive the machine before i make some kind of device to mount it in.

Then i realized that my wife can't take the thickness of that SilexD silicone dildo (it's 55mm wide) so i am making a mounting plate to screw on the end of the shaft so that we can use all of our slightly thinned suction cup dildo's.
Her favorite Dildo for pegging is the 9" RealRock (TPE) dildo (does not vibrate) an for vibration she loves the slightly shorter and thinner 8.5" Adam & Eve (TPE) rechargeable vibrating dildo.
The best vibrating toy is our purple Fun Factory Lady Bi, she gets hit on the clit by the rabbit, and her G-Spot gets hit the the main shaft with the curved tip.
The purple Strap-U-Evoke is another great vibrating strapless strapon toy that has an inflatable bulb to stop it from slipping out while pegging me, it fails at pegging as it does slip out of her when pressure is put on the shaft, but my wife loves using this but in reverse, she inserts the long shaft in her pussy and leaves the bulb un-inflated and has it press on her clit while the whole toy vibrates using the remote, or she just uses the bulb as a handle while thrusting the shaft in and out.
The pink Eternal Swan is a smaller strapless strapon type toy with great vibrations in the bulb and shaft, she often uses this toy when she is at home, she inserts it with the bulb in her pussy and wears a tight pair of nickers to hold the shaft against her clit.
