Song Dayong swallowed his daughter-in-law's piss, which had a slight whorish taste to it, and kept sucking on her urethral opening as if trying to suck out every last drop that hadn't come out.
Zhao Shiyu, bracing herself against the mountainside, trembled continuously, feeling her delicate urethral opening being powerfully sucked by her future father-in-law, as if emptying her bladder completely.
"Ah, ah, stop, stop sucking, ouch, it hurts, ah, ah, let me down quick, I, I can't take it, mmm, ah!"
Zhao Shiyu moaned, clutching Song Dayong's head tightly as her slit opened again, spurting out several gushes of cunt juice, which Song Dayong sucked into his mouth right from her slit.
By the time Song Dayong set Zhao Shiyu down, she was so weak she couldn't stand, and she slumped directly onto the pants spread out on the ground.
