With all due respect to ankleboots, I don't understand how anyone can drool over "rubber tits," as the model in his post obviously has. To each his own, I suppose, but I'll take small natural boobs over big fake ones every time.
Here's an example of a MILF with fantastic, smallish natural boobs and great, suckable nipples: Marisa Tomei! If you had a night with her, do you think you would regret that she didn't have inflated, silicone-implanted boobs? By the way, she is 43, which certainly qualifies her as a MILF by any standard.
