Looking for a specific shaped dildo for DV with the wife

Looking for a specific shaped dildo for the bedroom. The wife likes the fullness feeling of having myself and a dildo at the same time vaginally, however she doesn't love the stretch at the entrance of her vagina. We're thinking of a dildo that is a bit larger at the top, but slimmer at the base. Sounds silly, but sort of like a toy rocket? Also not too interested in very large fantasy-type dildos. Thanks!!
