Filling my s****r

... that I was now fucking my s****r, but then she pushed at my ass more and began to squeeze my cheeks as I went deeper into her pussy. Katie moaned heavily. I knew then what it was like, and what I was supposed to do. I began pumping Katie like I saw in the movies. She began stroking my back and squeezed at my ass some more. I felt intoxicated, I was actually fucking her, fucking Katie on our mom's couch. I put my head beside hers and buried it in the couch. Now I was the one hiding my face. We fucked like that for several minutes then Katie became more aggressive and f***ed me to fuck her harder and harder. She began to whimper a bit and was trying really hard to get off. Looking back I imagine she was becoming frustrated, but it didn't seem to bother her too much. She flipped around and got on top of me, it lasted about three rounds of her rising her pussy up and down my cock before I felt I was losing consciousness. As I squirted my cum inside of my s****r, I swear I felt my dick hitting her deep down inside somewhere. Her tits were bobbing in front of my face in an almost comical fashion.

The guilt I felt was more than I would ever feel again in my entire life. I immediately got up and went to my bedroom. I remember examining my dick in the morning light, and the embarrassment of having my and my s****r's cum intermixed all over my groin. I went back to sl**p in my bed and remember being awakened by the sound of my s****r taking a shower. At that point my mom was home and I was completely paranoid at how I was going to face my mom and my s****r in the same room together. As we went about our usual Sunday rituals my s****r and I maybe made eye contact once. She ended up going out with her friends later that day, as my mom went about her routine with no clue as to what happened. A few weeks went by and I had lost most of my quilt between us. I masturbated to our night together practically ever night since it happened, yet hadn't the balls to try to initiate it again. Until one weekend when my mom and her boyfriend took my s****r and I to Remmy Park. Remmy Park was an old swimming park that had slides and a picnic area, and not too much else. It had seen its heyday in the mid fifties and was close to being shut down. We got to ...
