Grandma Vivian's exposed buttocks (R18)

"With only the two of them left in the room, Grandma Vivian turned her head towards Orion and asked, "So, what brings you here? Is there anything I can help you with?" Her voice was filled with curiosity.

Orion gave a small smile and shook his head, "I'm just here because I was feeling bored. But if you have any tasks to do, I wouldn't mind lending a hand." He responded, cupping the other rear end of her bountiful cheeks. Surprisingly, he was beginning to miss the concept of panties and undergarments as that would have made his invasion of Grandma Vivian's bare buttocks a little more exciting and thrilling. 

Grandma Vivian nodded thoughtfully in response, "Well, since I don't follow the others to work, and Celia had decided to stay with me at home, I don't really have much to do except rest and wait until they came back".
