[LEYMEI] そうだ、 大改造じゃ!! (性転換アンソロジーコミックス Vol.6) [英訳] [DL版]
#104809 - When he’s finally done cumming the cum is under painful pressure, but before I can do anything he starts fucking me again, his dick pushing deep into my uterus full of cum making it stretch so badly I nearly think it ruptured. As he keeps humping me, both of us joined together, I come to the realization that his knot and dick weren’t quite at full mast, but they are certainly heading there. She barks, then snaps at me, biting down on the scruff of my neck.
