That night, after their parents were asleep, Amy went to Kaitlyn"s room. "Kaitlyn?" Amy peeked in through the door. "I expected to see you tonight, sis. More education?" Amy nodded. She really wanted to see more of Kaitlyn"s body. Amy closed the door behind her. Kaitlyn was already nude, and Amy pulled off her gown on her way to Kaitlyn"s bed. "Is Andrew coming again tonight?" Amy asked. "No. His Grandparents are in town for the next week and he can"t get out at night. Have you ever let any one else pet you?" Kaitlyn coaxed. "No." Amy replied shyly.

"Why don"t you lay back and let your big sis take care of you.” Kaitlyn pleaded. Amy lay back in the bed with her legs slightly spread. Kaitlyn lay between Amy"s legs propped up on one elbow. She slowly touched the nearly hairless 18-year-old mound. She rubbed up and down over Amy"s vulva. Amy was in heaven. Involuntarily she spread her legs further, until they were spread as wide as they could go. This spreading parted her nether lips and Kaitlyn was given a good view of her stepsister"s pussy. She rubbed her hand into the slit and up and down. Amy moaned lightly and bit her lip to keep from being any louder. Kaitlyn"s hand was slippery with her sister’s juices she began to flick Amy"s little clitoris. Amy jumped at the first few flicks then settled into the shear pleasure of the experience. In just a minute her clitoris was swollen to twice normal size and with one last flick, she was cumming. This was more intense than any of her little cums in her secret place had been. Her little body shuddered over and over, until she finally calmed after a few minutes.

Kaitlyn smiled at her little sister. "Was that a good cum?” she asked. "That was the best!" Amy said emphatically. "Can I do you now?" Kaitlyn smiled again. "I want you to kiss me on my pussy." "Okay," Amy said, puzzled. She wasn"t sure why her sister wanted her to kiss her on her privates, on her pussy. But she decided it was worth trying.

Kaitlyn lay back, her large breasts jiggled a bit as she plopped back. She spread her legs widely, knowing what would come next. Amy lay between Kaitlyn"s legs and started to kiss her on the thigh. She wanted to work her way to her sister"s pussy slowly, just to tease her. She had no idea how erotic this would be to Kaitlyn. Kaitlyn"s breathing got heavier and she almost moaned a few times. Finally Amy reached her sister"s moist center. She kissed her directly on the clit. This time it was Kaitlyn"s turn to jump in pleasure. Amy began to lick and suck on Kaitlyn"s clit like a pro. In just minutes, Kaitlyn was shivering with orgasm. Amy moved up and sat down beside her sister. Kaitlyn lay still for a minute then Amy asked, "did YOU have a good cum, sis?" "It was the Best!" she replied. Both sisters giggled at the deja vu.

After a moment, Amy got up the courage to ask a question. "Kaitlyn, since I tried something new for you, will you try something for me?" "What?" Kaitlyn said. "Well," Amy hesitated, afraid of what her sister would think. "Would you put your finger in my bottom." "Ooough. I"d get it messy." Kaitlyn replied. "Okay." Amy began to pout as little girls can. After a minute Kaitlyn had an idea. "I"ll tell you what. I"ll get some surgical gloves from the hospital Tuesday and we can try it, okay?" "Okay!" Amy was excited again. "I"ve heard that the doctors sometimes have to use them for that. I think they call it a rectal exam. And this way I can do what you want and not get messy.
