After getting married, the older sister returned to her parents' home for the first time in a while, and asked her younger brother, "You haven't seen any other girl's pantyhose panties besides mine, have you?" When the younger brother answered, "O-of course not!", the older sister said, "Good boy! Then I have to give you a reward!" and started a pantyhose footjob. To the bewildered younger brother, the older sister showed a happy expression, saying, "As I thought, your dick is bigger than my husband's. It looks like it feels good!" The younger brother thought in his heart, "If she does this to me, I feel bad for her husband, but when I think about it, I loved my older sister before her husband did, and I'm the only one who can make her feel good with my dick!" and while smelling the nice scent of her pantyhose, he rubbed his dick against the pantyhose-covered butt and other areas as if marking her. Then the older sister, delighted, said, "Mmm, as I thought, it's bigger than my husband's!" and gave him a sticky, sucking blowjob. After that, when he inserted into her pussy, she felt, "It feels better than my husband's dick!" so the younger brother, determined that his older sister's pussy was his, thoroughly thrust his dick in and out violently to make her remember. And on top of that, he creampied her with a large amount of sperm.
