Welcome to Jana's Secret CovaThe Jana Cova Dual Pleasure represents that only way most guys are ever going to to get inside of Jana Cova. This is great if you're a fan. The mold looks pretty realistic with pink painted pussy lips contrasting well with the flesh colored base. The interior tunnels are short, connect, and are ridged to provide stimulation, but it isn't earth shaking. All in all, probably good for the true Jana Cova fan but there are better out there for the rest of us.
As for the size and fit of the toy, it is pretty tight but very stretchy. The tightness and overall lack of rigidity make this part of the toy hard to use for warm-up. You kind of need to already be erect to start using it. The vibrators may be useful to you for the warm-up however, so it can provide some help. Once you are erect the material is stretchy enough to allow for easy entry into either hole. The ass entry may be slightly tighter than the pussy entrance, but not too much. The length of the tunnel will leave most guys sliding out the other end during deep penetration, but keeping the tunnel focused on your head instead of your shaft isn't too difficult.
