Praxina and Mephisto were just chilling in the cave, they had failed again so they were planning their next evil plan to defeat the princesses.
It had been the millionth time they failed, and so Praxina was really pissed when Mephisto was not taking this seriously.
"Mephisto, stop resting, we must plan for the next battle!" Praxina ordered
"Girl chill it's been 20 minutes.." Mephisto groaned.
"Chill? What do you mean chill?! We should get going! " Praxina yelled.
"No way!"
"Yes way!"
"Nuh, uh!"
"Yuh, uh!"
"Nuh-" "SILENCE!" Gramorr's voice boomed through the waterfall.
The twins shook in fear because it was pretty untimely, like all the time but anyways.
"I have a.. special request for you both." Gramorr announced.
"What is it, your dark graciousness?" Mephisto asked.
Gramorr paused for a second, "I need you both to.. reproduce."
"WHAT?" The twins yelled at the same time.
What. Did. He. Just. Say?
"Listen to me closely, this is very important if we want to spread darkness across Ephedia, and for that we need dark magic children to continue the bloodline of darkness."
Gramorr added "And if you don't do it, well face major consequences. I expect you both to be ready by tonight, and I will be watching." And disappeared.
Mephisto and Praxina just look at each other in shock, why did their master want they to commit incest?
"We, we can't d-do this! this is DISGUSTING! Does he have a fetish?!" Mephisto yelled while shaking.
Praxina was also shaking, she didn't wanna do it with her brother, let alone the fact the baby would probably have defects.
Both were genuinely terrified, but knew they had to do it no matter what or else.
For the past hours, they tried to calm themselves down because they were literally about to loose their virginity.
"Calm down, you can do this" Praxina muttered to herself while trying to contain herself.
5 hours later.
It was finally time for them to do it, they shut the cave doors and put a mattress and a towel down. Gramorr was watching while sipping tea.
They looked at each other, and sighed. This was happening in this moment. They turned away from each other.
Mephisto unbuttoned his cloak and took off his shirt and pants, and Praxina did the same.
They reluctantly got on the mattress, they didn't even know what to do until Gramorr spoke up.
"You both really don't know?"
They shook their heads, obviously, they were still young why would they know?
Gramorr sighed very loudly, "Okay, so here's how it goes."
For the past couple of minutes, Gramorr gave Mephisto instructions. He was feeling really bad for his sister but it lowkey felt good too.
Praxina was sweating so hard, he was basically almost reaching her stomach, "i-i, cant" she yelled.
He tried to calm her down by holding her hands and her neck down with his mouth, but no use.
Eventually, he finally came, she almost screamed because this was very uncomfortable.
Mephisto wanted to leave, but knew Gramorr would be livid, so he just continued even though he knew both of them were hurting.
She looked down and saw how his cock was deep inside her, she wanted to gag, it was also very cold, and the bed was stained so bad.
After a few hours, Gramorr told them to stop and disappeared. They let out a sigh of relief and was breathing heavily.
"I, im really sorry sis" Mephisto muttered while trying to catch his breathe. Praxina didn't say anything but just nodded.
She got up, but barely could walk. She needed to shower, and she got her clothes and showered.
She couldn't stop thinking of it, but she couldn't deny it kind of felt good, and Mephisto didn't shower and just put on his clothes.
After it, they just sat in silence, they were still pondering on what happened, and the fact that Praxina was gonna be pregnant soon, since that's what this whole thing was for.
They just fell asleep, hoping to forget about this horrible night, and wish it was all just a bad nightmare.
