When I woke up in the alley the next morning with cuts and bruises all over my body, I realized I hadn’t JUST been mugged by my Bully and his friends. I had also been forced to watch my Sister receive the best fuck of her life and the image of her face as she came on my Bullies cocks would stick with me forever! Now I lay there naked - without a cell phone or I.D. - with a massive headache and a surprisingly erect cock.

    If her Brother ever got over his heartbreak long enough to find another Girlfriend, she was considering convincing the girl to break up with him as well so she could experience another intense orgasm like this again! 

    It was a horrible thing to think about, but she was getting so fucking wet from that thought that she was going to have to slide a hand between her legs and have another orgasm!

    I had absolutely no clue my little Sister fantasized about me fucking her Bully until I was accidentally woken up by her moaning in bed last night.

    I had no clue my sweet and innocent Sister wanted to see my hard dick sliding in and out of her Bullies tight wet pussy as her Bully teased and taunted her with every thrust I made. But the idea was kinda hot and I was becoming rock hard just from imagining her watching me! 

    I had to jerk off a dozen times that night just to get the thoughts out of my head long enough to get back to sleep but the moment I woke up in the morning again, I was rock hard with lots of terrible thoughts about my little Sister and my little Sister's hot bitchy Bully filling my head! 

    I wonder if my little Sister really wanted me to do it, or if it was just a fantasy she got off to from time to time when she was really horny?

    Mutual masturbation with my Sister had gone a little too far.

    She and I were both masturbating separately in our bedroom a few hours after our parents went to bed until we begun overhearing each other moan. It was obvious we were listening to each other masturbate  and neither of us wanted to be the first to cum. So we lay there by the wall listening and edging as we both inched closer to an orgasm and moaned louder and louder for one another!

    This went on for a little while until my Sister decided it was time to stop dancing around what we really wanted and decided to text me about what she and I were doing. And after an unusual exchange of texts, we finally agreed to just have her sneak over to my bedroom and masturbate on my bed together - under the conduction that we just watch and not touch of course.

    Things were awkward in the beginning but started to go more smoothly once we begun to get comfortable touching ourselves in front of each other. And it was incredible looking my sibling in the eye and holding the edge as she whispered my name while touching herself a foot away from me!

    But things spiraled out of hand pretty quickly once my Sister begun to question what I was thinking about and in less than an hour after we had begun, things had gone a little too far!

    I soon found myself cuddling with my naked Sister, whispering in her ear and encouraging her to think about the man who Bullied me as I rubbed her soaking wet pussy. She seemed a bit hesitant to do so in the beginning because it seemed so wrong - but I could tell the thought was getting her wetter by the second!

    I knew she was going to cum HARD for my Bully!

    After her orgasm, my Sister confessed it was the most intense orgasm she had ever experienced and was a little embarrassed to admit it, but she wanted to do this again every night as well as telling me she was considering fucking my Bully for real one night if our parents ever left us home along - although she told me she wanted me to watch
