Kaisheng's "bird" is indeed a happy one, its feathers ruffling with excitement as he tenderly caresses it to life. His grip is firm yet gentle, a dance of contrast that sends shivers down his spine. The sight of his thick, veined shaft sliding in and out of his fist is a sight to behold, a symphony of flesh and desire that leaves him breathless. His body tenses, his balls tighten, and with a final, shuddering stroke, his happy bird sings its song of release.
