Ever since the night where they have started making out and doing sexual acts, Riko and Daiki became even more intimate and comfortable to each other. They no longer fight nor shout at each other's ears. Much to their parents' liking. Well they like it better than their childish quarrels before.

Little did they know, the two had already started an affair and that their keeping it a secret from them.

They were cautious so they wouldn't caught on their bitter sweet sin of having a "Siblings with Benefits" kind of relationship.

It was early in the morning and Riko's in the shower when Aomine suddenly bursted in.

"Aomi --MFFF!" He quickly shut her off as he gave her a passionate kiss in the lips. She broke it by force and she pushed him slightly away from her.

"You idiot! Just what the hell you're thinking!" She whispered indignantly.

"Nothing. I just miss you, Nee~san," he answered then he pinned her again to the wall and kissed her.

He nipped her neck, gently hitting her sensitive spot, she gasped and her body tensed from his sudden move. She tried to pushed him again but to no avail. He's way stronger than her and it was natural for he has the advantage of being male.

"Sto .... ooop. It already! You know we can't do it here. We might get caught!" She told him.

"It's fine. I'll just make it fast." That said he smirked on her and then resumed on what he had started. He inserted his tool on her and she whimpered when it was finally inside her.

Good thing the dripping sound of the running water coming from the shower was loud, louder than her noise. It's sound was perfect to conceal her moans of utter pleasure.

Once again, she controlled the volume of her voice as he made his thrusts faster 'til he reached his climax. He came inside her and when he pulled out his thing from her, a white thick liquid came gushing from her womanhood.

She immediately cleansed herself afterwards. They bathed together and when they're done they both went downstairs for a breakfast, with their school uniforms on.

It was never new to Riko everytime her step brother asks her to do lewd stuffs when he's bored or when he feels like doing it. It became one of their daily routine. At first, it was just a past time but as the days that past it soon became a hobby, an addiction they didn't know when to stop. They would even sneak when they both feel like doing it. Every night, he'd entered her room while the lights are off while in the morning, they'd go on a shower together.

They don't waste anytime they have when they're lone together. They're too thirsty for each other that they would do it whether their parents are home and are not.

Riko arrived at home after their club activities ended early. She saw Aoi in the kitchen when she came in. The older woman greeted her and her eyes shortly scanned their living room. Apparently, Aomine wasn't home yet.

The brunette just shrugged her shoulders as she went upstairs to her room to get change. When she's done, she went back downstairs and she helped her new mother in preparing their dinner.

"Excuse me, Riko~chan. I'll just go to the comfort room," said Aoi, leaving the younger girl alone.

The Seirin Coach was alone in the kitchen when another person came in. She just ignored it, thinking it was just her father.
