To prevent that from happening, Liu Yiru quickly gathered her remaining wits and mustered all her strength to stop her son just as he was about to thrust.
But her son didn't give her the chance. Just as his penis was less than two centimeters away from her pussy and she was about to stop him, he suddenly halted. He stayed in that position and began to rapidly masturbate with his hand.
The sudden stop made Liu Yiru sigh with relief. Her previously taut nerves instantly relaxed. But as soon as she let her guard down, the desire she had been suppressing surged back like a tidal wave.
The intense excitement from her son's penis being so close to her pussy made her involuntarily squirm, and her buttocks slightly lifted upward.
Liu Yiru's slight thrust was not significant, but her son's penis was too close to her pussy. This small movement unexpectedly pushed her bun-like pussy right onto his hot glans.
