Once they finished washing and getting dressed again, Mia and Amara went downstairs while Oliver stayed up in his room to get the answers he sought from his grandfather.
After all, he had to make sure that whatever caused him to act out in such a way could be avoided in the future so he could enjoy his life without any complications.
The moment the call connected, William asked immediately, "Oliver! Why are you calling now?"
"Uhh, there's something I need to ask." Oliver didn't bother beating around the bush with small talk. "Grandpa, didn't you inject me with the drug that would allow me to impregnate my relatives without worry? But somehow... the drug you gave me also made me much more... possessive. Do you know why?"
Silence followed as William didn't immediately respond to Oliver's question.
However, soon after, he answered with a laugh, "Ahhh, that... It might be because of your own feelings as well."
"Huh? My own feelings?"
"Well, you see... that drug can bring out hidden desires and instincts from within the person it is injected into."
Oliver was stunned by the news and couldn't help but frown as he tried to make sense of what he just heard.
"Wait, wait, wait... hidden desires and instincts?"
William chuckled once more as he continued, "Indeed. Let me explain further... Incest is seen as a taboo act by society and also by nature itself. Thus, most of the time, incestuous urges remain dormant within all living beings."
"However, that isn't the case for those who have been injected with the drug I gave you. Because of the special properties of that drug, the dormant incestuous urges within the recipient's mind awaken completely, and they are unleashed at full force."
"Moreover, since the partner is someone you love, your feelings toward the one you love amplify as well. As such, it's only natural you have such intense possessive urges."
Oliver didn't speak for a while, as he contemplated what his grandfather told him.
It sounded reasonable.
There was no doubt that he did love his mom and sister to death, so he did want to keep them for himself forever.
The more he thought about it, the more he realized that he'd always been this possessive of them.
'It was just that... I never let it out. Because I felt guilty,' Oliver thought with realization. 'I felt guilty of the fact that their relationships would crumble because of me...'
And that was exactly what was holding him back, he believed.
However, when his grandfather injected him, all the repressed feelings were now released, amplified due to his love for them.
That was why he ended up losing all the guilt and hesitations and allowed his instincts to control him instead.
It was so simple in retrospect.
"That makes sense. Thanks, Grandpa." Oliver heaved a sigh of relief.
William then asked with a serious tone, "By the way, Oliver, did you get intimate with your aunt yet?"
The question startled Oliver for a split second. It was because he was expecting it, but not at this time.
"Yeah." Oliver decided to be honest with his grandfather. "Last night... I had sex with Aunt Anna. Why do you ask?"
"Hahaha!! Wonderful!" William exclaimed happily upon hearing that, as he seemed genuinely delighted. "That's my grandchild!"
Oliver's lips formed a wry smile upon seeing how happy his grandfather seemed.
Even though he was talking about his grandson having sex with his daughter, it sounded like William was the one receiving great pleasure from it instead.
But then again, William was so ill that he might be eager to see his bloodline live on, Oliver concluded.
"Okay, Grandpa. Thank you for clearing things up for me. And take care of yourself."
"Alright. You too. Remember to call me if anything else comes up. Goodbye for now, Oliver," William said before hanging up the phone.
After talking with William, Oliver's expression relaxed as he leaned back against his chair and closed his eyes while he took a deep breath to calm down.
'Everything's fine, then. That means this possessiveness and aggressiveness is a part of me. Nothing wrong about that,' Oliver thought in reassurance to himself. 'Besides, I'm sure Amara and Mom won't mind anyway. I'll just have to be mindful of how far I'm pushing them, then.'
As he thought of that, Oliver got up and left the room to go and join others for breakfast.
When he arrived in the dining room, there were only four people who were having breakfast: Amara, Mia, his aunt Anna, and his father, Adam.
Mia noticed Oliver and waved him over. "Oliver, hurry up. Let's have breakfast first before discussing what we're going to do."
"Sure, Mom." Oliver went over to kiss his mother's cheek first before moving towards his aunt Anna. He leaned in and said in a whisper, "Sorry, Aunt Anna. I couldn't come to you after training. Let me make it up to you later."
Anna looked surprised at first, but then she flashed a faint smile and said, "You don't have to worry about that. After all, I'm sure you had something else to take care of. But next time..."
Oliver didn't let her finish that sentence and gave her a deep, passionate kiss right then and there.
Anna was shocked at his sudden actions. Yet, she soon responded to him and deepened the kiss as well.
Their tongues intertwined together as they engaged in a heated exchange that caused their lips to lock perfectly with one another, not letting each other go.
Her soft, plump breasts also rubbed against his firm chest as their bodies pressed up against each other's.
And then, the kiss ended, and he parted from his aunt, much to her dismay and disappointment.
"Umm... Let's go ahead and eat together. Shall we?" Oliver gave Anna a cheeky grin, knowing full well what she felt after being kissed like that.
Anna sighed internally and replied with a faint smile, "Of course."
Adam watched all of that from the side and shook his head. "My boy is being quite open and aggressive, it seems. To think he would even make a move on his aunt like that... Well, he sure gets that from his father."
Mia, who overheard that comment, rolled her eyes as she said, "Seriously? Do you have any self-awareness about yourself, Adam?"
"Huh? Of course I do. How else would I have gotten you?" Adam flashed a proud smile towards Mia, who scoffed before returning her gaze towards Oliver.
"Oliver, you better not get too close to your aunt. She's my sister, so I know full well she isn't a very nice person. She's selfish and greedy and will suck you dry if you let her."
"__"
Anna didn't make a sound but turned towards her older twin sister and gave her a sharp glare that caused a shiver to run through Mia's back.
But Mia wasn't one to back down either, so she glared right back at her with just as much intensity and ferocity as they engaged in a showdown that left everyone else feeling uncomfortable.
Seeing how intense things were becoming, Oliver spoke in a low but stern tone, "Let's just eat our food."
Anna and Mia instantly stopped glaring at each other and returned to eating their respective meals, acting as if nothing happened between them.
Although that brief exchange only lasted for a couple of seconds, it left Oliver worried for their relationship in the future, fearing that things could escalate beyond what he could handle.
However, when he caught them looking at him with teasing expressions on their faces, he realized it was all just playful banter, and he ended up being played like a fiddle.
'These sisters are too troublesome... I should find some way to control them, or they'll just keep pushing my buttons...' Oliver thought.
But in the end, he realized he didn't care that much. It was always fun to engage in little quarrels like these.
