A secret sex movie by Erisa Kusunoki, My girlfriend has a very beautiful best friend named Erisa. Because her family is holding a memorial service for her grandfather, she will be going back to her hometown for three days. Because she is worried that I will have an affair, my girlfriend asked Erisa to watch over me, at least according to Erisa. Even though I know I shouldn’t have any other thoughts about my girlfriend’s best friend, I can’t take my eyes off her G-cup breasts! Knowing that I was staring at her breasts, Erisa not only didn’t get angry but also said to me: “If you can hold back for two days today and tomorrow, then I will let you fuck me on the last day.” I was both surprised and happy at Erisa’s invitation. And in order to be able to fuck my girlfriend’s beautiful best friend, I struggled to hold back for two days. By the third day, my sexual desire had fully erupted! No matter how many times I ejaculate, my cock stays hard as ever!
