A month has passed at the Aldas home with Apius and Caetia learning from an AI teacher. Laius asked the two what they'd prefer of which Caetia was incredibly eager to learn from a AI program. Apius wasn't too bothered at the thought, he did want to spend more time with his Dad and little sister. The chance at avoiding other kids was a bonus on top. Laius would join and help the two with practical lessons to make sure they were getting all the education they can get. When the month did pass Laius was paralyzed with uncertainty. His urges were strong and overwhelming but he had done it, he kept his promise and that empowered him. But his dick was often erect around his kids, he could feel the awkwardness at times when he was with his son. Apius would notice to which Laius would look away or leave the room in a hurry. Laius wanted to spend time with his son without his erections, Apius just wanted his Dad to be happy and comfortable. Laius sighed as he stared at the wall at the opposite end of the room, he sat at the end of his bed hugging a pillow. He heard a thump behind him with the bed bouncing slightly, Caetia stood up hugging her Dad climbing over him.
"Morning Dad!" Her voice was really cheerful, she kept on fumbling around trying to grip her feet on him.
"Morning Caetia." Laius turned and smiled back at her, he kissed her on the cheek to which she giggled in response.
"1 month! 1 month! Yay Dad!" She cheered loudly, eventually sitting around Laius's shoulder. He felt the warmth of her legs around his neck, he couldn't stop thinking of her pussy up against him. He was never fond of the idea of vaginal sex when he first experienced it. Alnia would joke that he was a closet case and give him a playful shove each time. But he knew she was giving him jest, she was the most solid turian he has ever met. She was strong, stoic, assertive and outgoing. Caetia held onto Laius's mandibles and he returned by holding onto her knees to make sure she didn't fall over. Just feeling her touch right now gave him thoughts and feelings, thoughts and feelings he wishes he didn't experience most of the time. But he wasn't in full control at this point, feeling the pressure for sexual exploration rising. It didn't help that he kept thinking about Alnia, the strong turian wife who cried during anal. He'd never seen her cry until she took anal, something of which she threatened him to not tell anyone partly as a joke but also to not have rumours of her. Laius remembered that sex so vividly and as he felt his daughter on top of him he drifted into reminiscing about he and Alnia. First time she cried yes, but the second time was the best one yet with Alnia. She was prepared and it was a much better experience for the two. After they were done she got him to eat her out and that was all that she wanted. The afterglow had them holding each other thinking of the future. Alnia didn't care what her family thought, Laius didn't want to care. After that second anal experience she asked for two kids at the least. She felt ready to have a family with her childhood friend, willing to be a kickass Mum as much as she is a kickass security guard. Those following moments were the only times he gave her vaginal. 

"Daddy my thingy feels weird against your neck!" Caetia giggled to her Dad, starting to swing on him. Laius snapped out of his reminiscing and chuckled in response.
"You want down then?" Suddenly Caetia flipped back and off of Laius plopping on the bed. She laughed at the stunt she had pulled and Laius turned around cuddling her on the bed. He kissed her on the cheek a few times, "You little scamp." Caetia laughed even more as he kissed her. Laius paused suddenly as he felt something snap in his mind, he was losing control and pulled himself away from his daughter. Caetia didn't know anything amiss of the situation and kept rolling on his bed. Laius was slightly hyperventilating and faced away, rubbing his forehead in frustration.
"Daddy?" Caetia spoke up with a pleasant grin.
"Yes Caetia?"
"Can you do what you do with Api with me?" Apius was walking by when he heard her ask that question, he quietly stood near the door but out of site.
"I don't know about that." Laius replies, feeling something in his throat causing troubles.
"But I want to have what Api gets." Apius shuffled a bit feeling a gut wrenching feeling in his stomach. Caetia didn't know any better, Apius felt responsible. But he remembered his Dad saying it will never be his fault so he breathed to calm himself. He entered the room running a bit before jumping on the bed.
"Api!"
"Hey Cae, hey Dad." Caetia grabbed and hugged her brother tightly. Laius struggling to reply he turned around with a half smile to his kids.
"Good morning Apius, I hope you slept well."
"I did yeah." Apius paused for a bit and looked up at his Dad. "Dad? I want to say thanks for keeping your promise, I hope you won't suffer more now."
"Apius you know that I want to do stuff to you and Caetia."
"Me, me, me-me-me-me-me!" Caetia starting shouting in excited as she let go of her brother to bounce on the bed. Apius hugged his Dad muttering 'I love you', Laius rubbed his son's head. 
"If anything I want it to not hurt much or at all." Apius added, Laius sighed and gave in. He didn't know why it took Apius to tell him it was ok for him to go but he felt relieved a bit.
"Api will you watch?"
"Watch what?"
"What Daddy does! I want you to watch!"
"Ok sure, can I have my Gamepad?"
"Of course, Apius. If Caetia is going to force you to watch then bring whatever you need to be comfortable." Laius added. Caetia squealed loudly in excitement, screaming about how excited she was to get what her brother got. Apius covered his ear holes and looked at his Dad, Laius did the same making out a pained smile causing Apius to laugh a bit.

As Laius went to grab equipment he told Caetia to have a shower first in order to be really clean for what's going to happen. Apius delayed grabbing his Gamepad and took is sister to the shower to join her as well to make sure she is thoroughly clean. She couldn't keep still in the shower as Apius make sure every nook and cranny was clean. He also cleaned Caetia's buttocks just in case. When the two was done Caetia dried herself in a rush and ran back to her father's bedroom and sat on the bed. She remained bobbing up and down on the bed with a big grin muttering to herself of excitement. Apius followed shortly with his Gamepad causing Caetia to run over and hug him once more. Apius didn't mind how clingy his sister was, he is seldom impatient with her and she loves him very much. The two sat on the bed with Apius playing on the pad with Caetia resting her head on her brother's shoulder watching. Laius entered the room with a box of dildos of various sizes, a few different bottles of lube and some clean wipes.
"That's a big box!" Caetia grinned as Laius opened it up distributing the parts neatly on the bed. Apius went and sat up against the wall with the pillows Laius uses to sleep with giving space to his Dad and sister.
"Indeed it is." Laius replied with a bit out of breath. He was excited yes, but a part of him was aching. A strong desire to fulfill himself but a part of him made me regretting everything. "Now. Caetia we are going to have to prepare yourself."
"OK! I'm ready!" Caetia yelled in a squeak.
"No, Caetia I mean to get your body to be ready." Caetia giggled in his response. "Caetia, look at me." He paused and got her to calm down enough to look at him in the eye. "I understand you are excited but Daddy needs you to follow what he says." Caetia nodded vigorously and bit her tongue gently at Laius. Laius looked at Apius and nodded to him, he made a promise to be careful with Caetia. No losing control and end up hurting her. Apius nodded back with a slight smile, he was feeling tense from the situation as it was weighing on him a lot but hearing his Dad and seeing him conduct himself like this made Apius feel relieved.
"What do I do?" Caetia yelled once more. Laius grabbed one bottle of lube, unscrewed the cap and ejected it onto the smallest dildo he had in the box. It was the size of a little finger, like the size of Caetia's and Apius's.
"Ok, so Daddy will now ask. Which hole does he stick this in?"
"My butt!" Caetia cheered. Laius was puzzled at first, he thought she was going to say her pussy.
"Are you sure?"
"There's no where else to put it!" Laius could feel the confusion and he rubbed his right mandible.
"Caetia you are a girl. Girls have two holes, one is right there," he poked her pussy causing her to giggle. "And your butt, obviously. So where-"
"My butt!" Caetia laughed more.
"You really want it in your butt?"
"Apius got it there. I want it there. I don't want it in my front bum. I want it in my bum bum!" Laius huffed in amusement, shaking his head and Apius wide eyed stared back in amazement.
"Ok Caetia. You want what Apius got?" Laius had to make sure, he's never been so unsure about sex so much in his life as he is right now.
"Yes! Hee hee." Laius nodded in response, smiled sweetly at his little girl and kissed her on the forehead.
"Then we shall put it there. Do you like that spot?"
"Yes! Cause Api has it so I love it!" Apius lent over and poked his sister and she retaliated with a poke of hers. The two of them laughed causing Laius to follow suit.

Laius got the well lubed dildo in one hand and the bottle in the other. He squeezed the bottle and pointed it to Caetia's anus. She broke down into hysterical laughter as soon as it touched her.
"That's cold!"
"Sorry, sorry. It will stop being cold in a minute." Laius put the bottle down and rubbed her anus with lube, spreading it across and around gently. He probed her gently getting her to giggle, she laid back on the bed and stretched her left arm to her brother. He grabbed and held her hand.
"This feels funny, weird and nice." Caetia couldn't stop smiling, she looked to her brother and and waved with her other hand, Apius smiled back. Laius slowly pushed his finger in more into her butt to spread the lube inside, he also wanted to feel the delightful warmth of it wrapped around his finger. After 2 minutes he pulled his finger out and swapped hands with the didlo and gently pressed it into her. He gently pushed and pulled it in her to make sure her anus to loosen and relax. He kissed her pussy gently causing her to laugh.
"I like that, it's ticklish!"
"I will kiss you more then." He kissed her more on her lips, the flavour of her skin and the juices from within was remarkable. He remembered doing this with Alnia but didn't find it nearly as nice as Caetia's. "How are you doing, Cae?"
"My butt feels weird but nice. I like the kisses!" Apius looked over to watch what his Dad was doing, he couldn't help but wonder what that was like. So much he had to ask.
"Can I kiss you there, Cae?"
"Yay! Yes you can!" Apius moved over and kisses his sister's pussy. He could taste his Dad's breath and saliva on it, but the aroma of his sister's spot and the flavour was something different. He didn't know what to make of it, but it was nice. Laius stuck his finger into her pussy causing her to perk up and slap his finger. "No!" Laius and Apius were taken back in the sudden mood swing.
"I'm sorry, Caetia! I didn't mean to do something upset you."
"I didn't like that."
"I can see, Daddy's sorry."
"That's ok!" Her mood swung back to her happy, cheery self.
"You didn't like Daddy's finger in your front bum?"
"No. I didn't like that." She paused to giggle, "I like it, my bum. But I like kisses." Her sentences were breaking a bit but Laius got the message. He looked at Apius who smiled back, Apius couldn't help but remember his Dad saying to say 'No' when they mean no. This reassured him more, his Dad did weird stuff to his sister and him. Wrong stuff. But he was still their father, he loved them so much. He couldn't hate his Dad. Laius continued pushing the small dildo into Caetia's ass being calculated and careful with what he was doing. He would mutter how proud he was of his daughter. Apius sat cross legged watching over his father and sister and grabbed his Gamepad to continue playing his game. Laius removed the small dildo and grabbed a bigger one, Laius got his kids to use one like this before so he knew Caetia could take it. He lubed it well and with his spare hand checked on his daughter's anus, lightly pulling it open and rubbing it.

"Ok Caetia, it's time for mr. purple." Caetia giggled and sat up a little bit, "Going to need you to keep your legs apart and up, grab around your knees and pull them to yourself. Ok?"
"Ok!" Caetia laid back once more and pulled her legs into her. This allowed Laius to slowly push the purple dildo into her, she huffed and breathed deeply as it entered her. Having this dildo back in her felt nice, she didn't quite know why. It made her pussy twitch a little as her anus clenched around it. A slight moment of discomfort set in, alarming Laius.
"Caetia I need you to relax yourself. Think about us all in bed cuddling. Relax, my girl. Relax." Apius put down his Gamepad and held his sister's hand with both of his. He looked at her in concern to only have her look back with a happy and relaxed smile.
"I love you, Api! I love you, Dad!" Caetia cheered, feeling the discomfort dissipate the dildo got all the way in. Laius left the dildo in her in order to get up and rub the side of his daughter's face. She squealed softly and followed up with giggling. She was just so joyful, so energetic. It put both Laius and Apius at ease.
"There's a surprise for you Caetia." Laius rubbed her cheek once more.
"What surprise?" She asked back.
"This dildo is slightly different from the last one. This one has a shaky mode, vibration. It will jiggle you. Would you like to try it?"
"That sounds funny! Yes!" Laius sat back comfortably and flicked a switch at the base of the dildo. A buzz sound started up and vibrated causing Caetia to constantly laugh. She let go of Apius's hand and reached down to her pussy and held her hand there to feel the vibrations. 
"I didn't know it had that." Apius queried. Laius smiled slightly at his son,
"I honestly forgot to use this. I was feeling so bad before I didn't want to use it on you. Apparently Caetia really likes it."
"My bum feels funny and ni-i-i-i-ce. Haaaa-haaa-hahaa." Caetia pulled the dildo out and kept laughing on the bed, rolling to her side to face Apius. "I like that, I like that. That was funny!" Laius grabbed the vibrating dildo and turned it off. He couldn't help but smell it, normally an object being inserted into one's anal colon it would stink. But Apius really got Caetia cleaned. He couldn't help but find the smell of ass as pleasant. Caetia sat up a bit and stuck a finger into her hole and gasped.
"What's wrong darling?" Laius in a momentary concern.
"My butt is loose, soft and squishy! It feels like to stick my finger in there." She stuck it deeply in, pulled it out and licked her finger. Laius and Apius in great concern they both quickly acted.
"Caetia! That is very dirty you shouldn't do that." Laius commanded. He grabbed a clean wipe, grabbed Caetia's hand and cleaned her finger.
"It wasn't bad!"
"You shouldn't do that. I don't want you to become sick, you can get very sick if you do that."
"But you lick and kiss Api's butt. Why you not get sick?" Caetia made a good point and Laius knew it.
"Caetia I don't want you to do that willy-nilly. I don't want you to do it when you aren't clean." He paused so he could make sure her finger was cleaned. "In moments like this, it should be fine. Daddy is just being careful."
"Ok." Caetia sounded disappointed but quickly changed her tone quickly. "Can you lick and kiss my butt like my front bum?" Laius didn't want to deny an opportunity. He felt sick inside but he was already in the middle of this, he had to do it.
"Of course I can. Just your bum?"
"Yes." She giggled. Apius grabbed his Gamepad and continued playing his game, for some reason he felt embarrassed to watch this.

Laius pulled Caetia's bottom up to him, she laid between his legs with his cock over her arm. She giggled at the size and hardness of his cock, that and having her rear end pulled upward like she was doing a handstand. Laius stroked his daughter's legs slightly pushing them downward and softly licked his daughter's asshole. He would occasionally get one hand to spread open her anus and finger it more open, licking the anal juices that came out. His mandibles shuffled slightly with each deep lick causing Caetia to giggle. Laius lost track of time, he rimmed, kissed, prodded his daughter for 30minutes. Saliva all over Caetia's butt and small down her back and waist. Caetia enjoyed it all, even when she stopped laughing and allowed her Dad to continue. She peered over to Apius and talked to him in the meanwhile. Apius felt weirded out that his little sister in the midst of being eating out to want to talk to him about what game he was playing. Caetia was so casual about what was going on, probably because she saw all what Apius went through. As she chatted with him Apius felt relieved that his sister was alright. The two talked and talked about the game 'Lifepod Ventures', Caetia would occasionally laugh from what her Dad was doing but otherwise kept talking with Apius. Suddenly Laius ejaculated across the room, he held his daughter's low waist to himself and grunted in shock. His throbbing member just shaking in extraordinary pleasure and sucked his daughter's asshole. Caetia laughed at the sudden sucking and Apius was taken back by how fast and how much his father shot.
"Holy wow Dad!" Exclaimed Apius. A bit of cum dripped onto Caetia's upper chest and face. She swiped a bit and stuck it in her mouth.
"Pizza!" She yelled. The flavour was so distinct to her. Laius huffed in exhaustion and recovering from immense pleasure. He removed his mouth from his daughter's butt and eased her down back to lying flat on the bed. "My butt feels good!"
"I'm.. so sorry about all that. Daddy didn't mean to get lost in the moment. Are you ok Caetia?"
"Yes!" She giggled and sat upright, feeling slightly dizzy from being held upside down. She crawled her way to Apius and flopped onto him, causing Apius to put down his Gamepad. He was glad he just saved his game. "I'm sleepy." Caetia slurred a bit and giggled a bit. Laius got up to clean up the mess letting his kids hold each other, he was in a slight panic about what just happened.
"Hey Dad?"
"Yes Apius?"
"Can we all sleep together?" Laius paused a bit but nodded to himself.
"Sure we can. Daddy will just need to collect and clean things up. You two can stay here for now, Daddy will be back." He grabbed the dildos that were used, put them in a plastic container that was marked 'Dirty' and put the rest of the equipment back into the main box he brought into his room. He left the room with the box with dirty on it to get them cleaned. Apius put his Gamepad and put it on the bedside table, it had a picture of his Mum with all of them in a photo frame. Caetia moved over to the left of Apius and laid her head on the far left pillow. Apius laid down next to her and hugged her from behind. 
"Love you Api." She muttered, Apius squeezed her tight back.
"I love you too sis." After 10 minutes Laius came back into the room with his lying together, he smiled and sighed. He loved seeing his kids sleep together, the big brother hugging his sister close. Laius walked around to the other side of the bed behind Apius, got into bed and hugged the two of them.
"I love you two. Sleep well." Laius muttered to his kids sighing in relief.
"We love you too." The both of them replied tiredly back. The three of them laid together, with Apius in the middle. A short moment later Apius spoke up,
"Can we have the room colder? It's too hot."
"Of course Apius." Laius set the temperature down for it to be cold. But with the blanket and the three of them hugging it was only just comfortable cool. Laius felt so much love for his kids. Caetia was tired, happy and loved her family. Apius felt relieved, happy and loved his Dad and sister. The one month promise officially ended, to Laius this was the best way to celebrate it.
