You and Corey tell Lorelei that you want to be mermaids but you also want to be hermaphrodites, so Lorelei turns everyone into hermaphrodites with huge basketball sized breasts and basketball sized testicles. Barbara and Polly pair off to be a mated pair, Clarissa and Nina got off to be mates, Lorelei and Kelly became mates, then you and Corey went behind a rock and mated for hours getting each other pregnant.
Afterward a breeding age female mosasaur comes up to them and offers to unbirth them, share her blood and make them
Hermaphrodite mosasaur mermaids.
You all accept and minutes later the young females belly is heavy and bloated with your eight forms and you along with your new family spend eight months in her womb, growing 20 times larger becoming mosasaur mermaids talking to each other and
pleasuring each other in the amniotic fluid during their transformation and gestation, then on the final day of her pregnancy, her belly has become greatly distended and her water breaks, the sudden lack of amniotic fluid causes you, your mate and your sisters to one by one climb downward through her open cervix and be born pregnant, the eight of you thank your new Mom and she goes on her way.
You and your family find a series of massive trenches and caves to live in and fall asleep in the first cavern for well deserved post rebirth rest. Sharks and whales don't attack you anymore, but they do rub against your giant baby bumps as you sleep in respect of your new place above them in the food chain while guarding their future sea queens and their future young from attackers.
The new queens are emitting an array of energy powers that are having a great effect on the whale and shark females causing them to become instantly full term pregnant and orgasming immediately, they are grateful for their queens gift of great and refined fertility.
