Il più largo possibile - Tormento anale BDSM

I get a particularly deep insight when I stretch a man's asshole extremely far. For this I use a huge speculum from veterinary medicine. Very slowly I turn on the screw and spread his sphincter further apart. Inside I can see his heartbeat. What a sight and for him a hammer feeling. Do you want to experience this and let your German mistress stretch you so far anally? This is real BDSM.
