The clothespins are ready to pinch these titties!
It’s Christie Stevens at Hogtied.
It’s too over-the-top into BDSM land for Titty Blog, but this tumblr photo shows a pair of enhanced titties (you can see one of the scars) that have been pierced with heavy-gauge (and heavy!) rings and which are showing rather a lot of bruising. The overall impression is of a self-satisfied BDSM practitioner showing off, but of course your impressions may vary.
