Doing This At School Is Not A Good Idea, But I Like It + Back At Home Indulging Ourselves

She dragged me by my hand, not caring about the strange looks by the onlookers. It seems she was feeling a bit riled up too. I started matching her pace to make it look less weird. And we both smiled while doing something as stupid as running in the hallways to find a place for sex.

She brought me to what looked like a regular bathroom. Though it was completely empty due to the fact it was a bit hidden away, in a place most students had no reason to come to.

She pushes us into one of the male bathroom stalls in with an excited look, didn't even hesitate for a moment to take off my pants.

"Haah, finally." She said with an almost manic voice.

She pulled down her pants and sat atop of my lap. Putting my hand on her crotch and she doing the same to me. giving a much more ferocious handjob than before. I in turn, also became a lot more forceful than yesterday, playing around a bit until I found a spot she seemed to enjoy. Within moments we were already rearing to go, as she did not even put a moment of thought before forcing my part inside the soft prison. She could not keep herself in control as she forcefully rammed into me, all the while kissing me and playing with my chest. I did the same as I played around with her perked up nipples. But every moment she seemed to squeeze harder and harder. Her kisses were also becoming stronger and more forceful as it started to feel like she tried to mouth-rape me. Leaving me little room to gasp for breath.

As the sensation continued, just before I climax she squeezed down extremely tight, forcing out overy bit of cum I had to give. She looked at me dazedly, with a very satisfied expression. I looked at the time on my phone, wanting to say that break is almost over. But as if she'd read my mind, she put my phone away and said "Can't we just skip the next class?"

Without a furture moments thought I agreed. Class can go to hell for all I care.

Hearing the bell, she was already down on her knees in for of me as she started sucking me off. first playing with my exposed shaft with her tounge, then slowly leading it deeper inside her mouth. The newexperince, feeling the damp inside and her perfect lips on it made me only want to give her the biggest load I could give. As she was caressing my dick, I started thrusting slowly inside. Pleased, her face came closer to my base as my member seemed to be hitting her throat.

"I'm cumming." I said as I easily gave in to the sensation, trying to warn her beforehand.

But she just kept going and, as I came, sucked out and swallowed every bit of it, giving me an expression that said not to worry about it.

Even after I came she had not stopped, but only slowed down as to not hurt me. Only teasing it to slowly make it grow bigger again, as the cycle once again repeats.

We kept having sex until the next period started, at which point we decided to both say we're feeling a little ill, and resumed our activities back at home.

'At least I got to deliver the homework', I absentmindedly thought as we headed back home arms linked and kissing.

-----------------------

Before even properly being able to change I was already dragged to her room. The inside didn't look very girly, aside from a plushie she had kept all those years. The walls were painted a deep blue and some posters of metal bands hanged on it. Aside from the giant monitor and gaming equipment she only had a bed and cabinet similar to mine, and a clothesrack sitting beside the door.

She pushed me on the bed and closed the curtains. She then quickly undressed as I did the same. For the both of us at this point only expectation remained, as the tense atmosphere in the room wafted around us. She jumped on me again, not wanting to wait for even a moment long. We gasped heavily, still exhausted from our fast paced walks and endless fucking. But that didn't stop us from exhausting ourselves further. She gently rubbed her pussy against my dick, stroking it rhythmically. But at this point it felt more like teasing, as both our bodies grew impatient. I climber on top of her and inserted it immediately, giving her little time to react. I grabbed her by the waist as I got to see her cute expression, bewildered but unhesitatingly submissive. I went over further inside, hugging her tightly all the while, wanting to do anything to even get an inch closer. She hugged me tightly back, wrapping her arms and legs tightly around me, as a spider would do to it's prey. I patted her a bit roughly as I went on. going and going with her also doing so, lifting herself up to get even closer. We quickly came to the edge again, and I unhesitatingly released everything as my sister moaned in delight. After many, many hours again of unrelenting sex we finally came a bit to our senses again, completely exhausted.

"Do you want... to have a baby... with me?" She asked in a sweet, somewhat childish voice. I nodded, my throat much too parched to speak. She looked really happy. "Me too... together..." She sighed.

I gently lifted her up to the bathroom, deciding that taking a bath together should be fine. I wiped her off a bit and wahed her hair as her body seemes to have stopped listening to her. Her hair felt really soft to the touch. I was as careful as possible not to damage it, I gently massaged her temple all the while.

"Onii-chan, it feel nice." she absentmindedly commented, so I massaged the rest of her head too.

I lifted her us again as the water had filled the tub and laid her on my lap. I hugged her and fixed my posture to make sure her head would stay above the water. Her hands were splashing the water a bit.

"Say, onii-chan, can we do this more? Can we be even closer from now on?"

Of course we could, even though the road to it has been weird, I still want her to be with me.

"I love you very much. So much that I'll never let you go. No matter who wants to break us up."

Big words for an 18 year old. However I promise to stay true to that.

She gave a silent nod as we bathed together, rubbing our bodies and slowly again getting into the mood.

Gently we kept going and finishing before we went out the bath. I wanted to leave her at her room but instead she tugged at me to go to mine. I placed her on my bed and laid next to her as she hugged my chest from the side. We both soon fell into a deep, exhausted sleep.
