"Your power really matches you, A pervert got a pervert ability" Grace said with a little red face.
Lukas blatantly looked towards her black short pants she was wearing, it was a perfect fit so it outlined her beautiful curves perfectly and currently he could see a faint outline he was expecting, the soft, plump lips of her pussy pressed outward in a gentle, vertical crease that dipped invitingly at the center.
It wasn't the first time he was seeing it, he had a feeling that she don't wear her underwear inside the house anymore, maybe it was after one time she caught him looking at her ass, he had thought she was teasing him but was that the case? "As if you aren't one..."
Grace knew where he was looking but didn't flinch, "Not as big as you, eyeing both of your sisters humph!"
Lukas shrugged his shoulders, "A pervert is a pervert Grace, small or big didn't matter. Also, I forgot to tell you something..." his lips turned into a lecherous smile, his eyes were still fixed on her camel toe as she hadn't done anything to hide it.
Grace saw his smile and knew he was going to say something bad but she still asked, "What?"
Lukas finally looked at her beautiful face, "If you let me fill your womb, then you will evolve with 100% survivability rate... isn't it amazing"
Grace's eyes widened while her ears turned red hearing that but her heartbeat also escalated hearing 100% survivability rate, wouldn't that mean that she would be able to evolve, "Really?"
Hannah was also a little shocked, so that's how they would evolve, what if they get pregnant?
Lukas got dumbfounded hearing 'really' from her, "Forget it, I don't want a wife who didn't even believe her husband not to mention her brother whom she hugged to sleep like a pillow"
Grace blushed immediately, she really used to do that, "Shut up it's not up to you if you want me or not, I am 6 months older than you so as big sister it's my choice..."
Lukas became speechless, it was true, he was the youngest among them, "That won't give you the right to force yourself upon me, I wouldn't have listened to dad or mom for my marriage much less you"
Grace gritted her teeth but suddenly she calmed down, "So you won't take me in"
'Fuck'... Listening to her calm voice Lukas had a feeling that she had found a way to convince him and it definitely wasn't through begging which he wanted, definitely emotional blackmail.
Well in the end both of them knew that it was just a joke but he really didn't want to back off earlier. He had to say though, all went far easier than he had thought.
'In the end I really was stupid to not see through their feelings or maybe girls really are unreadable as they never gave me any clue', by now he might already have lost his virginity, what a stupid luck, "Fuck it, I am going to lose my virginity today no matter what"
Now it was both Hannah and Grace who got dumbfounded, "You said it out loud idiot brother"
When Lukas heard that he smirked, "It was meant to be heard, idiot sister of mine. Now let's get over it shall we, Grace I want you as my wife, say yes if you accept"
"Yes"
Not even a second passed when he heard her answer, he shook his head but inwardly he was extremely excited... 'I finally have full rights over my sisters'
He saw his system and as expected he have now tow harem members.
He than looked at them with a heated gaze as his voice turned utterly lustful, "Then should we begin, dear sisters. I am not able to control myself knowing that I have two wives and I still haven't seen a real pussy... don't say no as I won't listen"
Grace and Hannah suddenly looked at each other and immediately turned to look at him with steaming faces, Grace spoke with scrutiny, "What do you mean by that, you aren't planning to do it with us together right?"
Grace wasn't much averse to doing those things as she herself was very interested in doing it with Lukas but she felt a wave of embarrassment in doing it while being seen by Hannah whom she saw as big sister.
Hannah felt similar, she was already feeling utterly embarrassed just thinking about it much less doing it in front of her little sister, "D-Don't even think about it, I won't allow it..."
"Yes, no way" Grace chipped in.
Lukas sighed in regret but it's alright, it wouldn't take long removing their veil of embarrassment... 'I will make sure of it'... just imagining the scene of both their extremely beautiful faces licking his cock together gave him wild ecstasy
"Fine, your loss, then leave if you want Grace, I can't hold back now" he stood up while saying and removed the pillow which was covering his front and moved towards Hannah who was sitting in front of him.
Grace's eyes immediately went to his tightened cock and she trembled a little, Isn't this as big as in porn videos...
Hannah saw that Lukas really wouldn't stop now, she knew when he spoke seriously or jokingly, when she saw that Grace was standing petrified she spoke immediately, "L-leave Grace"
Grace came out of her stupor and immediately got red before running out of the room and closing the door.
CLANK!
She didn't go away though and sat by the door, she didn't want to peek inside as Hannah finds out then she will get embarrassed but she wants to listen and as long as Hannah didn't find out, it will be alright...
Lukas looked at Hannah's shy expression as she tried not to look at him and licked his lips like a hungry devil, "Sis..." He passed his hands towards her.
Hannah understood and shyly put her hands on his hands, suddenly she felt a strong tug and was pulled into Lukas' arms.
Lukas wrapped his hand around her back as he felt her boobs pressing against his chest.
