Transmigrated as side character, i will steal all the heroines

Ray closed his eyes for a sec, thinking that he had just imagined things. But when he opened his eyes again and saw Rena still looking at him with that determined gaze, he knew that shit was real.

" Rena, you don't have anything wrong in your brain, right?" Ray asked suspiciously.

Even though this thing was not as horrendous as NTR-Fetish, Ray was still a bit startled when Rena told him to hit her.

" No, Ray. Umm.. It's hard to explain, but just try it once. If it didn't work, then we'll just treat this as if we never had this conversation."

In the end, Rena was able to convince Ray, and even if he was a bit unwilling, Ray finally conceded.

He chose a body part of Rena that would not be so bad to hit. 

Yes, her buttock.

Amongst every body part of Rena, he would surely choose to hit her buttock if he had to choose.

Ray pulled Rena and put her into such a position that if someone else were looking at them, they would think that Ray was gonna push the naughty Rena by spanking.

" Rena, are you sure?" Ray asked one time just to make sure.

Still, the awaited answer didn't come, and Rena only nodded. Hiding her blushing face with her two hands.

' *Sigh* Do I really need to do this?...'

Ray was just talking to himself, but unknown to him, an existence hiding inside him was laughing her ass off right now.

[ DING!!! Well, don't worry, host, if you are still a bit unsure, then Aina will give you the motivation to do it.]

.

[ DING!!! A new mission has been issued.]

[ Spank Rena's buttock.]

[ Reward: Indomie.]

[ Penalty: You were forced to watch Ethan and Yuu playing sword for three hours.]

.

" .... "

' Really? Thank you, Aina...."

[ Well, no big deal, host. It is Aina's duty to help you.]

Ray was really speechless this time. Aina... Why did she really not know how to read the situation.

But complaining no was too late. The mission has been issued, and Ray didn't want to watch Yuu and Ethan playing sword with each other. Thus, he had no choice but to spank Rena.

He looked at Rena one more time, and after gaining the determination, Ray raised his hand high into the air.

' Please forgive me for this.'

The hand with moderate power fell into Rena's butt. At first, Ray thought he would just use a small power, but after receiving Aina's mission, he changed his mind.

Thinking of Aina's blackbelly, Ray knew that if it was not hard enough, the spank would not count, and he would be given a penalty.

Ray was ready if Rena was about to curse him or say that it was hurt. But even after waiting for a while, there was no response from Rena.

" Rena.. are you okay?" Ray was really concerned about Rena, but she still didn't reply, and only her body was shivering a bit.

[ Host, if she doesn't reply, how about spanking her a few more times?]

' You really have a black belly, aren't you? But thank you.. I like that idea.]

If Ray didn't have any idea on what was happening right now, he surely wasn't worth the more than thousands of hentai he had read before.

With another quick motion, Ray spanked Rena. But this time, it was harder than before.

And then...

"♡ Ahhhh....♡"

A sweat moan came from Rena's mouth, and Ray could feel her body was squirming.

' This girl... I never thought she was another pervert. Well, at least this was a lot better than NTR-Fetish.'

Rena's moan had confirmed Ray's suspicion. Thi girl's hidden side was none other than her masochistic side, and Ray was now a bit confused why he had not discovered this before.

Regardless, things have been discovered now, and Ray could sigh some relief. 

He looked at Rena's buttock, which was still squirming on his lap.

Immediately, an evil smile appeared on Ray's face, and he put his mouth closer to Rena's ear.

" You really enjoy this, aren't you? What a naughty woman."

" Ah... No..."

Rena's face turned red at Ray's remark. She tried to reject, but Ray's hand was ready for another spank.

*Spank*

"♡ Ahhhh....♡No.... "

*Spank*

"♡ Stop....♡"

Rena's mouth was saying no, but Ray could see the expectant gaze on her eyes. Furthermore, because Rena was placed on Ray's lap, he could also feel that Rena was getting wet down there.

With a few more spanks and harsh words from Ray, eventually, Rena couldn't hold back anymore and succumbed to the pleasure.

"♡ Ahhhh....♡Cumming.... "

Rena's body jolted, and her panty was now soaked in her wet juice. Her face was very ruddy, and her breath was rough. This cum just now was very intense, and Rena had never felt anything like this before.

Looking at her like this, Ray hugged Rena and placed her on the bed to let her rest for a bit.

The hidden side of Rena has been discovered, but now what? He really didn't think that this could be helpful to increase Rena's strength.

' Hey, Aina...' He was about to Ask Aina about this, but then something happened in the bedroom.

Rena's body which was lying motionlessly after her intense climax, now glowed with golden light, and Ray was dumbfounded.

' Don't tell me that she would power up just by cumming..'

[ DING!! You are correct, host. It seems the above-average intelligence stats was not wasted on you.]

Once again, ray was slapped by reality.

If he could rewind time, he would choose not to reject the system offer to be transmigrated as a protagonist.

Heck, one of the protagonists continuously power up by battling, and now the main heroine power up just by cumming.

Remembering his intense grinding and task, Ray somehow wanted to issue complaints to the world.

Soon a portal appeared next to Rena and Alice came out from it.

And just like Rena, Alice's body was also enveloped in golden light.

Half-king Level, Low-Level king.

Alice's aura surged, and in just one breakthrough, she had reached Low-Level king Spirit beast.

This breakthrough was still a bit far from Jean and Elsa, but considering it only needed Rena to cum once, this gain was still could be counted as over the top.
