My mom suddenly can't come, so Eimi-nee-san takes care of me instead! When my cock was seen while I was changing clothes, it swelled and she cried out in her mouth with concern, "Maybe it might be a sick..." and she couldn't stop squealing and white pee came out! However, the swelling didn't go away, so I pinched it between my breasts, licked it and rubbed it with my hands, and put it inside my crotch where the sticky medicine was coming out, and then I let it go over and over again! My sister's inside is warm and comfortable, and it's not like she's getting a white pussy! !
