Sophie couldnt resist temptation anymore.Shed been lusting after her younger brothers cock ever since they discovered their forbidden love affair last year, but now the temptation was too great to bear.As she approached him, he grinned wickedly.This will probably be the best fucking experience of your life, he said, his voice low and sultry.Without another word, he grabbed her and spun her around until she faced him, her body pressed against his own.Sophies eyes widened as she felt his massive erection pressing against her hip, his lips kissing her neck and shoulder before moving down to suckle on her cleavage.It was like nothing shed experienced before.As the two siblings lay on the bed together, Sophie spread her legs wide as he stood before her.He reached out with both hands and gripped her hips tightly, pulling her towards him and impaling himself inside her tight pussy.Fuck! Sophie moaned, her nails digging into his shoulders as he started fucking her hard.She closed her eyes and let herself get lost in the moment, the sensation of his thick cock stretching her open so intensely sending shivers down her spine.But something wasnt quite right.The feeling of being penetrated from behind was incredibly intense, too much so.Sophie turned around and looked back at her brothers face.Her eyes widened in shock as she saw his erection reaching her sphincter.Suddenly, it hit her what was happening.No.no.NO! she screamed, trying to shake him off.But it was too late.As he drove his cock deep into her ass, she could feel her anus stretching open like never before.It was such an unexpected and mindblowing sensation that Sophie had no idea how to react.This isnt right, she whispered, her voice trembling with fear.I dont want this.But her brother just laughed and continued fucking her with renewed vigor.Sister, this is fucking phenomenal! he exclaimed.He pulled her back onto the bed and flipped her onto her stomach, gripping her hips tight and thrusting himself inside her.Sophie gasped as he penetrated her tight asshole, going deeper and deeper with every movement.It was like nothing shed ever experienced before.As she pushed back against him, the feeling intensified, spreading waves of pleasure throughout her body.Soon, she found herself crying out in ecstasy, cumming harder than she ever had in her entire life.Yes, she moaned.Do it.And without hesitation, her brother pulled her onto his lap and lifted her to orgasm height, holding her tight as he fucked her ass faster and faster.The climax hit and Sophie screamed, coming all over his cock as it pulsed and filled her up.Finally, he released and pulled out of her asshole, turning around to look at her.That was.amazing, he breathed, wiping sweat from his brow.But Sophie was too shocked and embarrassed to speak.She rolled off of him and climbed onto the bed, trying to put as much distance between them as possible.It was one thing to fuck in private, but this was just too far.
