It was Halloween and Ben's family were gathering for dinner before everyone went their separate ways for the night. Ben sat at one end of the table, his mother and father at the other end, they were waiting for Ben's sister Ann to come down stairs and eat with them. Ben was already in costume for the Halloween party he was going to; he was dressed as a Jedi knight in long flowing Jedi robes, with a realistic looking light sabre on a belt. Suddenly Ann came running down the stairs, she was dressed as an airlines stewardess, but somewhat of a naughty version. Her tiny once piece out fit barely covered her tanned ass. Her long toned legs went on forever, and as she bounced across the wooden floor boards, Ben could see a hit of ass cheek, almost for sure she was wearing a thong. Ann wore her hair in two braids, and they hung down forwards, bouncing over her low cut blouse, her C cups jiggled as she ran to the dinner table.
Ben's dad looked up and barely noticed Ann, he was already pretty drunk, he was 8 cans in, and didn't register too much of the conversation around him. Ben's mom smiled as Ann sat down on Ben's left, she was very similar in looks to Ann, just turned 40, and she still had her appeal. Their parents started a family early, with Ben being 19 and Ann 18.
Their mother served dinner, and everyone chatted a bit, Ann smiled at Ben and gave him a little wink. The two of them had been fooling around for a few weeks, and any opportunity they got, they had a little fun together. Ann couldn't keep her hands of Ben's body. He swam 4 times a week, and hit the gym the other 3 days, he waxed all body hair, and was tanned from his work in the garden.
As Ann ate, she reached down with her right hand, slowly, so slowly, and slid her tiny fingers under his robe. The conversation moved to sports, and Ben's dad mumbled about the NFL, and everyone kind of just nodded along.
Ann worked her hand under Ben's robe, and moved his underwear aside. Ben was a little shocked, Ann had never been so bold before, and while their parent had no idea where their daughter's hands were it was a little scary.
Smiling ever so innocently at her parents, and nodding at all the sports related Dad talk, Ann gripped her tiny fist around her brother's ever growing cock. His 8 inches grew harder and harder, and she slowly pumped her fist up and down. Ben tried to keep a blank look on his face, as his sister stroked his 8 inches of hard fat cock, and with his left hand he slowly moved to slide his palm under her very short skirt.
