On the bed, Tang Yin's head bobbed up and down, with Tang Xiao's cock filling her mouth, mixed with soft sucking sounds.
She didn't insert his entire cock into her mouth, but only half of it. Her soft lips pressed and rubbed the skin on his shaft. Inside, her tongue moved swiftly, licking his glans and wetting it with her warm saliva.
Tang Xiao's eyes opened and closed repeatedly, enjoying the blowjob given by his big sister who was also his first wife. His mouth occasionally released soft moans as her tongue teased his glans, which was getting warm and wet with her saliva.
He looked at her, and his fingers slipped between strands of her black hair, gently and caringly caressing her head. "You're getting better at giving me a blowjob, Yin'er. I love your sucking and playing with your tongue on my glans."
She responded by pushing his little brother's cock deeper and sucking harder on it, electrifying him with pleasure all the way to the scalp of his head.
