Saeki Eri, a beautiful girl with a nice butt who looks good in tight pants and lives in the same apartment building, was cleaning the entrance and seemed to have a sore back! I invited her over to my house to have some medicine rubbed on her back! She showed me her round butt and her sexy thong! Naturally, I got aroused and ended up touching her butt! What?! Eri moans with pleasure! I want to hear more of her pleasure, so I have her sit on my face in a face-sitting position! As a thank you, she gives me a blowjob and then I insert my rock hard cock into her! I enjoy her beautiful butt and have creampie sex! The two of them become good friends and plan to have sex again the next day!?
