I know I've read a review about at least one harness which was able to be used with a dildo or vibrator for the one who wears the harnesses as well as the traditional dildo for someone else.

but I can't really find what I think I am remembering. Does anyone know any products or recall a review about something like that? less

Some of the Aslan Leather ones can work too - what you need to look for is something that rides low and has a hole beneath the O-ring. It probably isn't as good as the Outlaw offerings (the Outlaws look like they ride a little lower), but the Wonder Woman/Jaguar/Prince/et c. will all support an "innie" dildo as well. It's more comfortable if you get one that's angled, though. less

I dont know exactly how hell bent you are on wearing a harness, but another possible option is the Tantus Feeldoe. It's viewed as a harnessless harness. where it has a part that you insert, and the rest which you use on your partner. The four versions have a vibrating feature in the base of the product. With any Tantus that has a vibrating option, I've noticed the bullets they provide dont provide ample vibration. If wanting to up the intensity, the California Exotics 8-speed Accelerator Bullet works wonders..only downfall is there is a chord. less

I own the Aslan Cherry Jaguar and did a review which I should update. I was able to obtain a "cuff" that is attached to the butt straps and you just insert another dil to this cuff for internal penetration. I use the Tex, for one awesome ride.
I also found that with the low position of the harness, even with one dil, the wide base of a Vixen type dil provides waves of stimulation to my clit while I thrust.
The "cuff" is available from Babeland and also check the Aslan Leather site. The cuff can also be used to secure an anal plug but my butt holds plugs so I haven't tried it that way.

Spend some time making the initial adjustments prior to use...after that it is so easy and comfortable. I hate any interruptions during sex period. less
