Early next morning, when the sun had yet to rise above the outstretching horizon, Margret woke up in a weird position.
She was lying on her front, with her hips and ass raised up. She could smell the scent of her sweat clearly in the room mixed with more.
The heat within her vagina was burning intensely and she really wanted to relieve herself.
"Is it because of the dream I had?"
Margret got to her butt and thought. In that dream, she was getting fucked in her ass by a stranger.
It was hardcore and she moaned very heavily. The stranger had no face but his body was very sexy, and arousing in her eyes.
In the dream she enjoyed every moment with him even though she was basically getting dominated.
'No, I can't control it any longer!'
Unable to hold herself, she rushed towards the washroom to quickly masturbate.

The day passed rather quickly, and Ryan returned back home from school with Meti and Lisa.
"Tonight, Me and Meti will be busy in the restaurant so please take care of the house. I already prepared the dinner, eat when you're hungry."
Margret said before leaving the house with Meti in the afternoon.
Now alone with Lisa, Ryan thanked his mother for giving him another opportunity to twist his sister's mind.
Kind of like manipulating her.
In his room, Ryan started working out. He had to complete his exercise first. As always, he only wore underwear.
Almost a month had gone by since he had returned to the past and there was already a slight difference in his body.
Not only did he grow taller, he also became lean and much healthier than his past self.
Knock Knock.
"Come in."
He shifted his eyes towards the door and saw Lisa step in his room wearing a gray sports bra and underwear.
"Bro, can I also workout with you? I feel like I am getting fatter everyday since I began sucking your dick."
She stood on the side with a grin on her face. Ryan stopped and took a breath.
"Do some stretching first."
"Okay. But you need to help me."
"Fine, sis."
The two got into positions. Lisa sat down with her legs spread wide and her arms extended forward.
'She is really flexible.'
Ryan, from behind her, stared. He then pushed her and helped her to stretch her body.
Lisa changed her position multiple times. Finally, she got to her last. She laid on the mat, facing him. Her legs raised up and joined together.
"Come, bro."
She said in an inviting manner. Ryan sighed, it seemed he had fallen for his sister's trap.
The bulge in his underwear was a clear indication. And his sister was trying to make him fuck her.
"You wanted this, right?"
"Of course! Who wouldn't?"
Lisa gestured to him to get over to her. He grabbed her legs and pushed them onto her chest.
While doing so, his penis rubbed against her tight vagina sealed inside her sports underwear.
"Hehe. Do I feel it is correct? Bro, don't tell me you are already hard?"
"Shut up."
Ryan responded to her. He tried to not shove his penis through her underwear.
Lisa was like a slut as soon as she learned about the wonders of sex. She always asked for him to fuck her.
And it became frequent.
'I can feel her lower lips against my dick.'
Having thought enough, he wanted to get up but Lisa had other plans for the two of them.
She moved her legs and locked Ryan's neck, then rolled her bra up as she pulled his face on her soft and meaty breasts.
"Bro, I want to fuck."
"Every time?"
He looked at her not-so-innocent eyes and said in a low voice. Lisa smiled and used her hands to rub his face against her breasts.
Ryan's throbbing penis forced against her vagina' labias. Only the two thin clothes were restricting their further moves.
"You asked for this!"
Pulling down his underwear and sliding up her's, he positioned his penis on top of her wet vagina.
"Then quickly give it to me!"
Lisa replied in an erotic tone. Feeling his warm and pulsating penis on her crotch, a wider smile formed on her face.
Like she was going to be rewarded.
Ryan thrusted his penis deep inside her until the base, and stopped. Lisa gasped hard and clenched his head tightly.
Then he backed his hips and thrusted his penis again. He started slowly for both of them to enjoy, then as minutes passed, he fastened his movements.
"Ahhh! Ah! N-Nice, brother! I love your dick! Mmm!"
Attaining the heights of pleasure-land, Lisa declared loudly. Ryan bit her nipples and sucked her breasts like he does to Olivia.
After he mastered the art of pleasing with just their breasts, his next step was to control his own penis from ejaculating too soon.
"Sis, I am about to cum!"
"Hurry, do it in my mouth!"
Lisa ordered. She had him stand up and bring his penis right in front of her face, then she opened her mouth wide.
"Ahhg!"
Ryan stroked his penis and aimed at her mouth. With heavy moves, he released loads of semen.
"Emm!"
With the slightly salty and sweet semen in her mouth, Lisa moaned while she continued to finger herself.
Gulp… Swallowing all the semen, Lisa wiped her lips and took long breaths. She raised her head and looked up to Ryan.
He stood silently and looked at the mirror behind her, staring at their reflections.
"This is always the best."
Lisa commented as she kneeled before him and sucked his penis clean.
The bond between this brother and sister had successfully become twisted by the chains of sexual pleasure.
One of the few taboos in a family, now with Ryan and Lisa' constant intercourse, broke apart completely.
Of course, Ryan really didn't care. Not in the slightest bit. Instead, he wanted to do more things.
"Sis, we should shower."
"Hm. I will get the towels."
She left the room to get the towels and headed for the washroom. Soon Ryan joined her there.

Another week went by, the days didn't have much excitement to them.
Ryan didn't forget his workout, and interacted with everyone properly. His studies also were going well.
A normal class test was held that week, in which he scored third in his entire batch. Wonderful news for his family and friends.
Saturday, in the afternoon around 4:12 pm. Ryan was picking up his clothes when a strong gust of wind blew and took his school t-shirt to the neighbor's house.
"Tsk. Fucking wind."
Cursing under his breath, he stepped down the stairs and went outside.
The neighbor's house appeared rather gloomy from the road as there were no flowers or other decorations on the balcony or in the front yard.
Creak!
Ryan pushed the rusty gate which let out a high-pitched noise.
"Hello! Is anyone home?"
He called out to the neighbor because if he was suddenly caught walking in their lawn collecting his t-shirt, it would be a little embarrassing.
And they might even call him ill-mannered. That was how the world worked.
"Is no one home? My t-shirt was blown by the wind to your house, I just came to get it. I will immediately leave after I take my t-shirt!"
Since no one responded to him, Ryan sighed and walked towards their lawn where his school t-shirt had fallen.
"Arre?"
His t-shirt was nowhere in their lawn. It was weird. He was sure that he saw his t-shirt land on their lawn's unkempt grass.
Clank!
Then at that moment, the door to the lawn opened abruptly and a pale hand holding his school t-shirt peeped out.
The other hand also came out, and it gestured to him. Calling him inside.
