Pull her panties down

You move in for the other underwear, the last slips of fabric protecting her modesty. You see she's prudish though, wearing the straps of her garter over her panties. If those straps had been worn underneath the waistband of her panties it would have been considered naughtier, because that way the panties could be removed without unbuckling the garterstraps first.

You were going to make it naughty for her though. You unfasten the garter's straps, dig your fingers into the waisteband, and then pull, sliding them all the way down to her ankles to join her pants, and exposing her shaven cunny and her buttocks. Faint protests emerge from the bag.

You like the sight. It looks almost like the garter frames her crotch, without covering anything, and draws your gaze in that direction.
