Jerk off aid
 

Just found this on another site. It has various settings for stroke per minute speeds and some special settings.

I enjoyed using the 80 strokes per minute setting with ramp up running.:D

Stay away from the 200 strokes per minute as you will blow your load quickly.lol

Enjoy

SyncJack

what the link, syncjack leads to nothing

The link works for me.

Put syncjack into your browser, that should work.

I find this is cool but hard to use for small dicks because the penis on that site is much bigger so theres more motion.

I go faster than 200 I think, hard to keep in time at that speed anyway.

Different strokes for different folks.:D
