Whenever the weather is really warm, the two sisters love to play with their little friend in the sand pit. Today it was rather hot, so the children only wore short cotton panties. Little 4 years old Marion was completely occupied in building a sand castle. Her light blonde pig tails dangled over her narrow tanned shoulders. Her eight years old sister Sabine, white blonde, too, and her 7 years old Friend Julia were sitting on the edge of the sand pit letting their slender little legs swing.

Thoughtfully Sabine watched her little sister. Suddenly something came up to her mind. "You remember, what we always wanted to do?" Marion looked up. A wide grin flashed over her sweet little face. "Can we really try this today...?" Immediately she jumped to her feet, stripping down her little panty and lay down in the warm sand with wide spread legs. Her little rosy bulging cunny opened and presented her tiny firm clit and the scarlet entry to her vagina.

"I will be the doctor, Marion has to be operated, and you are the nurse!" Sabine commanded.

"Nurse, injection, please!" Sabine pointed to a tap, some yards away with a garden hose and a long nozzle attached.

Panting Julia dragged the hose, gave it to Sabine and ran back to the tap. "Turn it on for a test!" "Mrs. Doctor" commanded.

A thumb-thick jet shot almost ten yards far over the playground, then Julia turned it off again.

"Now we have to apply the injection, you will be operated now!" stated Sabine.

Marion had got quite anticipatingly shining eyes. Sabine grabbed the slim nozzle and put it to her little sister's wide spread vagina. The little girl gasped when she felt the cold metal slip between her yielding little nether lips. With turning and pushing Sabine pressed the nozzle further in Marion's abdomen. Inch after inch disappeared in this rosy orifice. Marion jerked up shortly, when her hymen tore away, then she relaxed immediately and watched fascinatedly her cunny being stretched inexorably. After squeezing about 4 inches into the child's vagina Sabine commanded: "Now the injection, nurse!" Julia understood and ran to the tap.

Marion held her breath and stared blankly, when she felt the cold water penetrate her cunt with a hissing noise. Excitedly the little girl grabbed her quickly swelling abdomen, when the high pressure drove the water into her bladder almost up to the bursting point, until Sabine gave the stop command.

"So, now please lie steady." she admonished the patient and jabbed the nozzle repeatedly into her little sister. "Nurse, put the patient steady, please!" she ordered Julia, when Marion began panting and struggling. Julia drew the little girl's slim legs firmly apart. Meanwhile Sabine took her sister's reddened clit between thumb and index finger and rubbed firmly, while she pushed the tool more and more violently into the extremely widened immature vagina of the little patient.

With a high pitched scream the little girl arched back, her abdomen jerking convulsively, then she fell back panting, a dazed expression on her face.

The 8 years old spread her fingers in a kinda professional way. "Nurse, the scalpel, please." Searching Julia looked around. Two young women sat talking on a bench at the edge of the playground, one of them obliviously pregnant.

"Scalpel's instantly coming, Mrs. Doctor". Quickly the seven years old ran over to the bench and squeezed herself to the young pregnant woman. "O, please, have you brought a knife?" Amazed the young woman looked at the child. "No, I have only this little scissors". She handed her little sharp manicure scissors to Julia. "Thank you; I think this will do. I'll return it after the operation".

Smilingly the women watched the little girl running back to the sand pit, then they continued chatting.

Sabine took the tool from Julia's hands and tested the sharpness with her finger nail. "Nicely sharp", she stated.....(cont)
