I'm reminded of a lady I used to chat with from years back.
She lived in a mid-sized Midwestern city, and began going on overnight ride-alongs with the local PD.
She wore clothing that looked ordinary on the outside, but was seductive underneath, and allowed easy access to anywhere she might get touched. It proved to be a temptation one younger officer couldn't resist.
He eventually took her to a place that was safe for them to park and began touching her underneath her shirt and in her pants, leading to him fingering her pussy. She said she was rubbing his cock through his pants, but was too nervous to actually take it out to suck it.
He then took her to a private apartment maintained by the cops as a play house off a back alley downtown, removed her top and his pants, and she gave him a proper blowjob.
She did this maybe 3-4 times over the course of several months, and it was the same stuff every time, always culminating with a blowjob in that little apartment. She said since she was much older than he was, and was self-conscious about her body appearance (thick), she was too embarrassed to let him see her totally naked, so they never fucked, but he enjoyed her sucking him off.
