The Prom was a night to remember, but nothing could have prepared us for what was about to happen.I was there, watching my sister get ready, admiring her beauty from every angle.Her dress hugged her curves perfectly, accentuating her long legs and tight ass.She looked like she belonged on the cover of a magazine, and I couldn't help but wonder how many men were going to be vying for her attention tonight.As we made our way to the dance floor, I couldn't help but feel a pang of jealousy.Here she was, looking more stunning than ever, while I was stuck here with no one but my own thoughts to keep me company.But as fate would have it, just as my sister and her date disappeared onto the dance floor, a group of guys approached me, eager to show off their skills and charm.I watched them dance, feeling their bodies sway and move in time with the music, but my eyes kept drifting back to my sister.She looked so happy, so alive, and I couldn't help but feel a twinge of desire deep down inside.It wasn't until one of the guys offered me a drink that I realized what I wanted.I needed to see my sister get fucked, right in front of me, and I knew that this was my chance to live out my wildest fantasies.I followed the guys outside, where they led me to a secluded area behind the building.There, under the flickering light of the moon, I watched as one of the guys pulled my sister aside and started kissing her deeply.Her hands wandered over his body, trailing along his broad shoulders and muscular chest, before moving down to the button of his pants.He unzipped them, revealing his huge cock, and my sister gasped in shock and delight.Without hesitation, she got down to her knees, taking his cock into her mouth and sucking him off passionately.I watched in awe as he moaned and groaned, his hips thrusting back and forth as he came harder and harder.When he finally finished, he pulled her up and turned her around, pressing her against the wall and fucking her hard from behind.My sister screamed with pleasure as he pounded her, his cock slipping in and out of her tight pussy with ease.She reached up and grabbed his arms, pulling him closer as he gave her what she wanted.I stood there, watching them intently, my own cock growing thick and hard at the sight of them together.Just when I thought things couldn't get any better, the other guys joined in, taking turns fucking my sister from different angles, filling her up and driving her crazy with desire.She screamed louder and louder, begging for more, her body shaking with every climax.I watched, mesmerized, as they took her, filling her up with cock after cock and leaving her wanting more.When they finally finished, they left her lying on the ground, panting and sweaty, with a smile on her face.I approached her slowly, feeling a mix of emotions as I saw her there, so beautiful and yet so vulnerable.But as I looked into her eyes, I knew that this was exactly what she wanted, what she needed.And as I kissed her deeply, my tongue exploring every inch of her wet, hot mouth, I felt a rush of satisfaction like nothing I had ever experienced before.The rest of the night passed in a blur of excitement and passion, as I continued to explore my sister's body, taking her from every angle and leaving her wanting more.We danced and laughed and loved, lost in the moment and letting go of our worries and fears.And as we made our way back to the prom, I couldn't help but feel grateful for this incredible night, and for the memories that we would cherish forever.
