He got out of the shower, just using a towel, drying his hair and body..

He went into his room but then he noticed his sister looking at him again...and again he noticed her flustered and blushing again..

He went up to her and looked at her right in the eyes before saying

I can see your obsessed with this huh?..

(IROHA'S POV)

She blushed and covered her mouth not knowing what to do and couldn't help but to look at him

(Sunghoon's pov)

He got closer and iroha could feel his breath

Why don't we just have fun since we're not doing anything..? Sunghoon then pulled her into his room. After he closed the door he started to kiss her lips deeply

Ain't this going to be fun?.. He said before carrying her to his bed and kissing her as he took off her clothes

*He countiued to take off her clothes. After that they started doing the 'thing'

Sunghoon: you won't tell anyone about this got it? ...now say you're a good girl..

Iroha: hmmm~.. i-im a g-g-good girl...

Sunghoon: good~... Sunghoon then moved faster every second making iroha moan more

Iroha: ahh~... please... keep doing this.... this feels so f*cking good..

Iroha: nghhh~...this is so good.. She said gripping on the sheets

Sunghoon smirked at her and moving faster

Sunghoon: I knew you'll like this.... you're such a good girl.. He said

The next day. Iroha was down stairs and was doing something in the kitchen when sunghoon called her smirking

Sunghoon: hey iroha..can you come in my room for a second..?

Iroha: sure Iroha then came up to his room as sunghoon quickly grabbed her and closed the door

Sunghoon: you said you're a good girl right? He said getting close to iroha's neck

Iroha: yes I did ....

Sunghoon: well we're going to do a new position today...

Iroha was confused about what sunghoon was talking about

Sunghoon: now listen..

He said before sitting down on the bed and spreading his legs and gesturing iroha to come closer.

Sunghoon: first...put your knee's on the ground...

Iroha then did sunghoon's command
