My girlfriend has a very beautiful best friend named Erisa. Because my girlfriend is going back to her hometown for her grandfather's funeral, she will be away for three days. Worried that I might cheat, my girlfriend asked Erisa to come and watch over me, at least that's what Erisa said. Even though I know I shouldn't have any thoughts about my girlfriend's best friend, I can't take my eyes off her G-cup breasts! Knowing that I am staring at her breasts, Erisa not only didn't get angry but also said to me, "If you can control yourself for the next two days and tomorrow, I will let you fuck me on the last day." I was both surprised and delighted by Erisa's invitation. And in order to have sex with my girlfriend's beautiful best friend, I struggled to control myself for two days. By the third day, my sexual desire was fully unleashed! No matter how many times I ejaculated, my cock remained as hard as ever!
