The wife and I are retired but we are no strangers to sex toys. A year ago I built her a platform stroker machine and she liked it. I knew if I was going to get us a saddle system it had to have stroke = The Buck. She has a blast on this baby and can ride it for several minutes maxed out but prefers the lower settings for long term joy.
As much as I like the machine and its quality, I do not think the MB team pulled off a very good design for the Vac-U-Lock attachments. We have many Doc Johnson toys and Vac-U-lock dildos but the MB Buck design produces a dildo that is way too long. I modified the DJ pedestal by cutting off 1.25" and did the same to the dildo. Now the wife can fully take it and still ride the front pad with her clit.
