Chapter 10 – Fondling Breasts

I didn't want to waste my time anymore, so I activated the timer and immediately afterwards put my hands on her chest.

"Mn!"

The moment my hands touched her Rina released a soft moan and she immediately pursed her lips, trying to avoid making any other sound.

To my surprise, I could immediately feel that she wasn't wearing a bra.

I almost lost control of myself and went wild with her breasts, kneading them without any control or care. But hey, it's not like I can be at fault for that. This was the first time in both of my lives that touched someone of the opposite sex, and it was my incredibly beautiful and cute half-sister.

I used every bit of my willpower to control myself and started to massage them carefully and gently.

Her breasts were perky and soft like one might expect from her age, easily changing their form with the moves of my hands and rapidly coming back to their original shape.

From what I could feel and see their size was easily a C-cup, almost reaching D-cup. They were definitely bigger than most twelve year old and the fact that they still would be growing more filled me with anticipation for the future.

"Mn... Nhm... Ighn... Mnmnn... Nhamm..."

At every move that my hands made Rina would moan, incapable to hide how much that stimulation was affecting her.

The way that her body was squirming due to my touch and the sexy moans that she released was incredibly erotic. I could feel my boxers getting much tighter due to the awakening of my little brother from downstairs.

I could feel my own breathing becoming rougher due to my growing arousal from the situation.

"Ghnm... Onii... chan... hanmn... not so... ignhm... much..."

She put her hands over mine as if trying to resist my movements, but I couldn't feel any resistance coming from them. If anything it was almost like she was trying to push my hands even more toward her.

Her eyes had grown misty like she was in some sort of trance. I could still see traces of embarrassment in her eyes, but the previous nervousness wasn't there anymore. It was replaced by other emotions that I didn't think I would see in her so soon.

Affection.

Desire.

Longing.

I had to use every bit of willpower that I had to not instantly push her down and have my way with her. I knew that if I were to do that it would probably reflect very negatively on the way that our relationship worked.

But I also didn't control myself completely.

I let my hands play with her breasts more roughly. I played with her chest more roughly than before.

"Nahm... not.. Ignnmh... soo strong... NHANHMNM..."

The moment that I put more strength in my hands her moans become even more intense and she started to show signs of having difficulty standing.

Before I forgot I did something that, in retrospect, I couldn't believe that I had forgotten.

I pinched her nipples.

"NHAAAMMNM"

The moment I did that Rina trembled all over, her legs buckle and she fell on the floor. I immediately caught her in my arms, preventing her from getting hurt and helping her to lie down on the ground.

Even though I knew what happened, it still was hard to believe that it happened so fast.

She had cummed.

I actually made her cum just by fondling her breasts.

The moment that fact settled itself in my brain something inside of me awakened. Something so primitive that I couldn't quite describe it.

I started to rub her breasts again, even more roughly than before. My hands played with them and changed their shape with even more rigor than before. My fingers twisted and pinched her nipples with a lot of strength.

"AHNNM... ONIIICHAAAAAN..."

Rina's voice was similar to an animal in heat, howling in arousal without being able to restrain herself. Her body was shaking uncontrollably on the ground while my hands were with her soft flesh over her shirt.

Her hand went back to mine, but even then she didn't really try to push me out of her. She was instead trying to help me stimulate her mounds of flesh.

She really liked what I was doing and wasn't trying, or was incapable, to hide it.

I was completely immersed in the sensation of her breasts over her chest in my hands, the arousal and sweetness in her voice, and the way that her body twitched every time she achieved an orgasm.

We stayed like that for a while, immersed in our depraved actions for some time, completely unaware of the passage of time.

Until finally...

*RING*RING*RING*RING*RING*

...the timer finally rang.

Hearing its sound I was finally awakened from the strange state of mind that I was in, and I immediately took my hands out from her breasts.

Rina was down on the floor, her twin tails completely disheveled, her chest going up and down due to her heavy and rough breathing. Her eyes were misty and dazed like she had just woken up from a wonderful dream.

Despite all of that I could see that her attention was completely focused on me. I was able to see how much affection she had for me.

I couldn't hold myself completely anymore and my face moved closer to her. Before she was able to realize what was happening I kissed her. Nothing really serious, just a peck on the lips.

After the kiss I could see by her expression, eyes widened and mouth half-open, how much she was surprised by what I just did.

I could only smile helplessly at that sight.

"Sorry, you just looked so cute that I couldn't help myself"

My words had a great effect on her, since she avoided looking in my direction and her face turned to a very intense shade of red in embarrassment.

Yep, she really is cute.
