Dress on LetMeJizz
A tight dress stays on or gets shoved up instead of coming off, the fabric hiked over the hips so she can get fucked while still half-clothed. The action usually starts with hands sliding under the hem and panties pulled aside, the dress framing her ass or tits as it rides higher. Heels and cocktail wear or office looks push the effect, the idea being she is too worked up to bother undressing.
