Although in the past, aside from his mother, his mother-in-law, Ye Zhilin, and the recently acquired Yan Ruyu, no other woman had ever made Ye Fei involuntarily ejaculate, he could still build up his pleasure to a certain extent and then actively release it for them.
However, this time, since his sister's uterus lacked the contracting and sucking ability of her cunt, Ye Fei's pleasure was far from reaching its peak.
Nevertheless, the purpose of this encounter was to comfort his sister and relieve her pent-up desire from the past few days, so Ye Fei's satisfaction wasn't of great importance.
Moreover, time was of the essence. Thus, when his sister climaxed for the seventh time, Ye Fei also voluntarily released his semen, spraying large amounts of thick, hot ejaculate directly into his sister's uterus.
