You explain to your egg sack lover that it'll take 3 days for the eggs to come out of her, as you sleep for most of those days. Suddenly, as day 3 occurred, Sarina felt pain in her own stomach, meaning it was time for the eggs to come out of her. "Ah, Aria wake up," Sarina says. "The eggs are coming. We're going to be mothers."
You wake up hearing this, and go over to your egg sack, as she was struggling. Seeing this, you remove the webbing covering her pussy, and find small white egg coming out of her. Once that egg was out, you find a bunch more come out at a rapid rate, as it Sarina had her own tentacle inside the privates. You then take all the eggs, and put them in a nest out of your old knight uniform for them to lay on. Sarina laid about 12 eggs in one setting, believing that's how many eggs the spider in you can lay.
You check on Sarina just after placing all of the eggs in the made nest, and see that she was sweating after spilling out all 12 eggs at once. "It's alright, Aria," Sarina says. "I'm fine. But my, your eggs were sure hard to-" Sarina stopped her sentence, and then felt something.
