You laughed and were about to make a suggestion when you felt a strange pressure building up in your midsection. You placed your hands on it and frowned at the sight of your formerly flat stomach pushing outwards slightly. "Hmm," you said and then gasped as your belly started rapidly pushing outwards.
You wriggled out of Lauren's grasp and then dove for the sea floor. "What's with her?" asked Amber. You guessed she wasn't able to see your distended belly from her position above you. None of that mattered though.
Something had been activated in you and right now every instinct in your body was screaming at you to dig a hole. You began using your tail to scrape away the sand beneath you and soon you were left with a pretty deep pit.
Lauren's hand was on your shoulder. "What's going on- Oh shit!" Lauren said. You suspected that she had seen your belly, which had now reached the size of a woman about to give birth and was still growing.
Ignoring Lauren you placed yourself so that your slit was over the hole and waited for the changes to stop. The others seemed to be speaking in panicked tones but you couldn't hear them. Your whole world had concentrated to a single point as you felt the development in your belly finally stop. You'd heard that birth was supposed to hurt but as the first egg emerged you moaned out in pleasure.
Roughly the size of softballs, you felt a dozen eggs leave your body and you sighed as the afterglow of your birth washed over you. As you filled in the hole and buried your eggs you looked up into the shocked expression of the other mermaids watching you, especially Amber, whose cock had retreated back into its pouch. "That felt amazing," you said with a smile. You looked at the rest of the girls besides Amber. "Really, the rest of you should try it."
