The third generation of the Asshole Sisters works hard on high-level anal training. The fierce 1-on-1 anal instruction begins with the monster ass-fucker teacher Rui Negoto, who is seriously addicted to the chrysanthemum. She demonstrates a bizarre play where she inserts a 120cm, 10kg alien tentacle using only her legs. Although shocked by the otherworldly, wide-open, fully ripe hole, the novice anal-lover Oto Misaki also bites on. With a relentless giant cock 3-hole sandwich, both of their gears shift up. They flow their energy from their throats to their asses and pussies, aiming for even higher pleasure with total anal concentration. Before they know it, anal squirt bursts out! A record of the passionate training of two women who achieved rapid growth and transformed into magnificent ass-beasts, experiencing a torrent of anal orgasms.
