I couldn't help myself. There he was, my friend's husband, Marcio, sprawled out on a towel, his big cock hard and ready. I slipped off my panties, my big butt cheeks jiggling with anticipation. I climbed on top of him, my tight, shaved pussy rubbing against his throbbing BBC. He groaned, grabbing my big tits, squeezing them roughly. I slipped him inside me, my pussy stretching to accommodate his size. I rode him hard, my body bouncing, my big tits slapping against his chest. He grabbed my hips, pulling me down as he thrust up, filling me completely. I felt him cumming, his hot load filling my pussy. I collapsed on top of him, panting, my body covered in sweat and cum.
