Looking for a long and thin o-ring compatible dildo for a wearable dildo…

I’d like to find a good quality o-ring compatible dildo for a strap-on dildo that is long and thin. Preferably one with an insertable length of 7″ or more and a circumference close to 1.25″. Preferably realistic, but any suggestions that fit those dimensions would be appreciated. Thanks for any help anyone can offer.
