Like it's been said already in this thread, most guys first discover for themselves when using a decent sized dildo to get their wife off, just how much better she likes having her pussy full or even stretched out during sex. He actually gets to see her lust filled eyes, the coy sexy smile on her face, the harder than normal sensitive rubbery nipples on her pert titties, the extra wetness of her open pussy, the exposed nib of her excited clit, her legs spread wider apart then normal making for easier/deeper access for the bigger (be it only) fake cock, her pelvis rotating in time to meet the cock thrust, the louder than normal moans involuntary escaping her sexy lips while being answered by the sloshing sound coming from deep within her other set of lips, her breathing is fast/irregular, her head tilted back and tossing from side to side, her entire body is quivering and shaking, her moaning become more audible and she starts begging to be fucked harder, deeper, faster, for you not to stop, you know she's having orgasm after orgasm or is it just one continuous orgasm that is rolling through her in wave after wave. Eventually she reaches and stops you thrusting the dildo and holds it still, pressed firmly deep inside her trembling pussy. All of a sudden you finally realise why she still mentions her ex-boyfriend from time to time.
