Custom: My sister has the biggest ass. I wish I could burry my cock between her ass cheeks and cum all over her big ass. I went outside to get a closer look of her thong and she asked me to get her lotion. I can make you some lotion, I said. She did not believe me. I bet I can sis. I started to take out my cock and she told me to go inside. I followed her and pulled out my cock. She could not believe how big it was. She got on her knees and titty fucked me and then she bent over and I let out a big load all over her ass. Oh, no, mom is home. She told me to quickly get under her on the bed and as soon as she laid on top of me I started fucking her and grinding my cock in her ass cheeks until I cum again
