The masochist is tied up on all fours on the bed and cannot escape. To dilate the man’s anus, the mistress cuts a hole in his underwear, observes his anus, laughs, and inserts her finger into it and stirs it around. Next, mistress inserts a dildo into man’s anus and plays with it, moving it in and out. Then, mistress further dilates man’s anus with a larger dildo. Mistress puts on a strapon and makes man suck on strapon’s dick, giggling. When mistress puts the dick deep into man’s throat, he retched, but mistress grins and doesn’t stop. When the dick is sufficiently wet, mistress inserts it into man’s anus in doggy style and fucks him repeatedly. When man’s anus is considerably dilated, mistress inserts her fist into his anus and moves it in and out, laughing. And finally, she presses an extra-large dildo, thicker than the fist, against man’s anus. Then, when mistress pushed the dildo with all her might, man’s anus swallowed it completely.
