The guard proceeds to feel her up

The guard who is a muscular black man, is now standing directly behind Katy, her rear pressed against his crotch as he reaches around her to continue the search for the item.

He cups her perky breasts in his hands and squeezes them, presumably to find the contraband. Not finding anything he gently pinches her nipples which cause her to gasp. Moments later he pulls the low-cut neckline of her tight dress down and lets her breasts bounce free.

You find the silhouette of her perky breasts backlit against the fire to be an amazingly erotic site. Katy looks at you and mouths, "It's ok" at you.

After a minute or two of fondling her naked breasts, the guard runs his hands down her sides until they reach the hem of her short knit dress. He pulls the stretchy fabric up above her waist, revealing your friend's beautiful naked rear framed by a black garter-belt which is holding up her sheer black stockings.

He begins to grope and squeeze her rear like he though he would immediately find a gun on it.

You are self-aware that your cock is rock hard and perhaps you think you should be slightly embarrassed getting turned on watching your friend being explored by another man.
