A minute account of my 1st anal sex with my sister

We just finished an intense session of foreplay and were winding down. We both were still naked as we were unwinding in our own thoughts. I looked over and I saw her nakedness and I got hard again and wanted her again but the moon light was shining through the window and it shown on her naked body and she looked beautiful and had a light creamy pink color and her butt was there facing me as she was resting with her face facing the other way. I moved my way closer and I slid her closer to me. I cupped her breast buds and my weenie was rock hard and I kissed her back and I wasn’t really planning it but I guess it was the heat of the moment. I position myself and guide my weenie towards her butthole and I was cupping her breast at the same time and used my other hand to push my weenie inside her butthole. It felt really tight and no lube was used because I had no clue about what needed to be done since my sister and I were both virgins and were learning together as we pleasured each other. When I was putting it in her butt she whimpered a bit but held on to my hand as I kissed her back. I slowly entered her tightness and it felt warm yet tight yet gobbled my weenie as I slowly insert more into her. She tightens her hand into my hand and moves a little to allow my weenie to keep going into her butthole. I’m in as far as I can get it in and I pull out and reinsert it as my hands are wrapped around her tummy and hips as I thrust inside her butthole once again. I hold onto her hips and tummy and use her body as a brace as I thrust again into her butthole as my hand feels her hairy mound and I lightly insert my finger inside her pulsating hairy vagina. My legs are brushing against the back of her legs and my feet brush against her soles of her tiny feet I recently had in my mouth before we rested. I must have thrusted about seven times before I lost it and ejaculated inside her butthole and she let out muttered moans. I was spent after I pulled out and my weenie was wet and slimy but there was no sign of ejaculation on my weenie or from her butthole. We lay there nude and no words were spoken as I held her by her waist as my orgasm faded and she was on the verge of sleeping. I then kissed her butt cheeks and her back as I gently handed her clothes for her to put on as I myself got dressed. It was probably close to midnight after we finished our deed and I went back to my room to sleep and she stood in the television room and went to bed on the thin mattress size foam piece. We did our sexual pleasure play on the carpet. I’m not sure forty years later if I actually ejaculated inside her butthole or if it was a dry ejaculation since I had already ejaculated twice during the earlier session. I ejaculated into a wad of toilet paper. As a recall she had no overt order and a very light hint of feces as I entered her. My sister had a light salty taste to her body and a pleasant smell of soap and water. In my heart I wanted to enter her vagina and she would guide my weenie to her opening but I could not enter her out of love and fear. I had a condom that I kept under her pillow in case I wanted to enter her vagina and I was close on many occasions to put it on and let her guide my hardness inside her wet hairy vagina but deep in my heart she was my sister and I didn’t want to accidentally impregnate her as hell would break loose but most importantly to me it was not my place to be her first. I wanted her to experience that first with someone special and not me, her brother. However I did enter her butthole and it was our first intercourse but in her butthole rather than her vagina. We both wanted it to happen and there was no regrets. A couple years later the sexual pleasure relationship just stopped abruptly and we lived our lives without shame.
