Babysitting Sis

He hated it when his parents made him babysit his sister, after all he was sixteen and would much rather hang around with his buddies ogling girls his own age at the mall. His sister was just a few weeks shy of her thirteenth birthday, and in his opinion, still a silly little girl. As soon as their parents left, he told her to find something to do and leave him alone, as he wanted to give his best friend a call and tell him about the new girl he’d spotted that afternoon. He heard her stomp up the stairs as he dialed the number, but then the two boys became so engrossed in their conversation that he never heard her come back downstairs and slip out the sliding doors to the pool area. The boys talked for a few more minutes and then hung up, and he realized that he needed to get something for his sister and himself to eat. He went into the kitchen and made a couple of sandwiches, grabbed some chips from the bag for each plate, and yelled for his sister to come and eat. There was no response.

He went looking through the house, checking her room and the bathrooms, the den and family rooms only to find them all empty. As he was approaching the sliding doors he heard a splash and realized that she was in the pool. He opened the door and yelled again for her to come eat, turning away as he did to head back to the kitchen. She followed him in a minute later, clad in a bikini that left little of her young body concealed. The pale blue cloth stretched over her already somewhat developed breasts and ass, but failed to hide the erect nipples and alluring outline of her sweet virgin pussy. Suddenly he realized that his sister was becoming quite a charming and sexy young lady, and he turned away from her quickly, going to the fridge to get them sodas to hide the fast growing bulge in his shorts.
