When they let me in, S immediately started undressing for me, while M, naked with his huge cock already fully erect, watched with an amused smile. I sat on the edge of the bed, my cock already straining against the black panties I wore for the occasion, as S climbed on top of M and began to ride him. I watched in fascination as she took his massive black cock deep inside her, moaning and begging for more. The way she looked at him and glanced at me every now and then, the way she moved her body - it was like nothing I'd ever seen before. I felt a strange mix of humiliation and arousal as I watched him fuck her right in front of me. When S finally came, she loudly moaned his name.

Afterwards M disappeared into the bathroom, leaving just the sound of the shower running, S patted the space beside her on the bed. Her eyes sparkled with mischief as she invited me to join her, pulling the sheets up to cover her naked body. "Come here, baby," she whispered, her voice husky from the recent orgasm. I hesitantly climbed in beside her, my own cock still painfully hard. S wrapped her arms around me, pulling me close. "You did so good just watching," she cooed, her hand drifting down to grasp my throbbing cock. "Now it's your turn." She began to stroke me slowly, her thumb playing with my foreskin, watching my face as I melted into her touch. "You liked watching me with him, didn't you?" she asked, her voice soft in my ear. I could only nod, my head empty and dazed as her hand brought me closer and closer to the edge...

We decided to keep in touch, so maybe I am allowed to watch them more in the future :)
