Tantus harness and and Vac-u-lock harness HELP ??

Hi all,

My partner and I would love some help or advice. We currently own a http://www.lovehoney.co.uk/product.cfm?p=16829 and the http://www.lovehoney.co.uk/product.cfm?p=18073

Now the issue we kinda have is we love the doc johnson harness, its easy to put on and comfortable for my partner, but the dildo that comes with it is far to big for me, depth and width. But we do like using the dildo that came with the Tantus bend over kit (the medium sized one) and the bullet pocket, but if we are really honest the harness is quite uncomfortable and a pain in the arse to put on in a hurry.

So finally my question is does anyone know of an attachment that can convert the vac-u-lock harness to an O-Ring harness? or if not has anyone got an idea how we can adapt it.

If neither are possible can anyone reccomend a very good O-ring harness that if possible can house a bullet.

Thank you for your time and help.

Mercedes and Jenny xx
