Sometimes things just happen, and for me, that is what did happen in the most shocking of ways. When I moved into a new apartment I was renting and setting up, my brother had been helping me and we were both grungy and dirt covered.
Now mind you, my brother and me have showered togeather before growing up, and nothing odd ever happened, so this time appeared to be no exception, though as he washed my back, the tingling sensations become rather intense and got my desires turned on and upward in intensity, to the point my nipples started to swell in desire.
I mean it, this was genuine lust building; just getting touched in the right way, and it had never happened like this before — it both excited and scared me at once.
Brother kept working my back, sides, and upper legs with a soft rag, and I had to brace on the wall with my hands to keep my balance, and this time though, I turned around and looked him in the face when he stood up fully.
My smile was kind of crazy looking he later said, but the two of us knew some line was crossed now and there was to be no going back. We hugged each other and the first kiss was awkward, and the feeling of his erection down between my thighs was as well. It just took off from there, with our hands exploring, and touching one another.
We did not even dry off, he just walked me over to my bed, an old ragged day bed, and we went down on it. Shortly, we were beyond kissing, and beyond just fondling. I told him to fuck me, and while it hurt greatly to begin with, it was soon enough a enjoyment like I never imagined. He did cum inside me too, which I was not too happy about though I did not get pregnant.
We still make love every now and them; my brother and my lover, the best combo ever.
