to grade a "character" is not just how hot the model is. big boobs/ass/body/face etc. 50% is the personality and history.
for me Vanessa is a pure slut. theres no challenge. just dip my dick a sloppy second. no need to corrupt her, she will corrupt me instead. she has issues? theres no remedy here, she will and can not change.
Ann is naive and innocent and the MC can shape her into any directions. she is cute enough and a nice ass and even if shes not as hot as Vanessa she wins with who she is. I hope she will continue to be naive and cute even if she takes multiple cocks. Im not sure about Alex, I think shes even hotter than Vanessa, but theres something about her personality that is not working for me. maybe she will change and I will think differently. but surely for me Alex is better than Vanessa. as for the others, Im not that interested yet. Emily is growing on me but need more content to decide.
