Cassie Cummings and Nikola Ophan plan to play a spooky game called The Moo Summoning. The rules are simple: Look into a mirror with only the light of a candle to light the room and moo three times. Cassie is scared but Nikola reassures her that nothing will actually happen. It's just a game! So the two girls light their candle and moo into the mirror. As the third moo leaves their lips, the candle flame flickers as if blown out but it recovers in time to show them their summoning ritual has worked! There's a bimbo hucow standing right behind them!! Sydney Screams moos and the girls panic and run. What did they just do? Was it real? Shortly after escaping, Sydney the futanari hucow approaches them again mooing and offering her giant dick to them. Unphased, Nikola tells Cassie that she knows what to do now and to just follow along. They get onto their knees in front of the massive futa cock and begin blowing it together. This is easy, they think! How many dicks have they blown already. It's bigger, but no different. Their tongues and lips feel so good that soon Sydney's mooing becomes frantic and her cock explodes, covering them both in futa hucow cum! They wipe the cum from their eyes to discover they've been changed by the sticky load. Not only can they understand Sydney's mooing but they've been transformed into futanari bimbo hucows themselves! Sydney calms them down and informs them about the changes they're experiencing and how their lives will be forever altered. Cassie and Nikola happily bounce and moo along without fully realizing the transformation has already begun to change them....
