LULU-384 - Unable to resist the provocation of my older sister's exposed, large buttocks, I secretly ejaculated on her while she was wearing clothes due to overwhelming sexual desire. She immediately noticed, so I desperately tried to cover it up with forceful piston-like thrusts, repeatedly ejaculating inside her. Shirahara Sayu.

My older sister's buttocks are so alluring...! Unable to resist her large buttocks while she was hanging laundry, I approached from behind and secretly ejaculated on her. I thought I wouldn't be noticed, but I was immediately caught, so I used the confusion to quickly cover it up with forceful piston-like thrusts. Her vagina felt so good as she moved intensely, forgetting she had been ejaculated on, that I repeatedly ejaculated inside her. From that day on, whenever I saw my sister's buttocks, I couldn't suppress the urge to ejaculate on them and secretly did so multiple times.
