"We used to take baths together when we were little," she said, not caring about me being upset. "Let's peel it off," she carefully cleaned the dirt from the head to every nook and cranny, and I ended up getting a full erection. "It tickles me, big sister..." she gently stroked the tip. The tingling sensation on my sensitive head was irresistible! "My penis has gotten hard... I can't help it, lol" she gave me a handjob and blowjob, ball-licking handjob, no-hands blowjob, and deep throat. She made me cum many times with naughty things and cleaned up the inside of my balls. "Don't tell mom and dad," she said, giving my beloved big sister a handjob in the bath and making me cum on her chest! We had sex and she made me cum inside her vagina without pulling out! She cleaned up my dirty penis again with a blowjob, and I cum in her mouth for a total of four times! G-cup Nori-chan.
