your girlfriend Mallow sent you to buy some ice cream so they could enjoy their day at the beach, then you would apply sunscreen to her beautiful body, however when you came back it seems that someone had already gone ahead...it was the Kahuna Olivia!, who applied what It seemed to be sunscreen on Mallo in a vastly good and erotic way, so much so that Mallow trembled with pleasure as she rubbed her big ass on Olivia's pussy
Olivia: "Look who we have here! I'm sorry my friend, but you were late for your girl so I decided to take care of it, okay?" Olivia continued rubbing Mallow's body while she gave her her ass "ahh don't worry girl, then I'll go to your big ass if that's what you want!"
Mallow: drooling with pleasure, her body trembled and she just continued rubbing her ass on Olivia "ahhhh...yes Miss Olivia, I'm all for you, for your enjoyment and...OHH boyfriend!, there you were...me ...well you took a long time and mhh, Miss Olivia offered to help me...ahh and she does it so well!"
