A joke about eels

Seven-year-old Xiaoming, like other boys of the same age, is just more curious. He heard a lot of rumors about "courtship" from other boys and wanted to find out what was going on.

One day, he asked his mother this question. His mother found it difficult to talk, so she let him hide behind the living room window one night to see what his sister and boyfriend were doing. Xiaoming did as his mother said. The next morning, Xiao Ming told his mother everything he saw that night.

He said: My sister and her boyfriend sat and talked all afternoon, and then they turned off most of the lights. Later, her boyfriend started hugging and kissing her. I think my sister may be a little uncomfortable because her face is strange (her boyfriend must think so), because he put his hand under her shirt to touch her heartbeat like a doctor, but he didn't do as well as a doctor because he didn't seem to touch her heartbeat. Then my sister's boyfriend began to feel uncomfortable, because soon they began to gasp and have difficulty breathing. His hands must be getting cold, because he put them under his sister's skirt. At this time, my sister retreated to the end of the sofa. I think she may have started to have a fever because her hand grabbed her chest and told her boyfriend, "I feel so hot!" " 」

I finally found out why they were uncomfortable. ...

A "big eel" suddenly ran out of his pants. It jumped out of his pants and stood upright. Yes, it is about eight or nine inches long. Then he grabbed the eel with one hand to prevent it from running away. My sister must be very scared when she sees eels. Because her eyes were wide open and her mouth was wide open, she said to her boyfriend, "Wow! Oh, my God! 」

I really want to tell my sister that I have seen eels. There is really nothing to be afraid of. But my sister suddenly became brave and tried to kill the eels by biting their heads. Suddenly, she spit out the eel. I think it may have bitten her. At this time, my sister's boyfriend held the eel tightly in his hands, took out a condom from his pocket and put it down from the eel's head to prevent it from biting again. Then she lay back and put it down. Sisters can lock eels like scissors, and boyfriends press the top of eels with their bodies. At this time, the eel was caught in the dilemma of being attacked on both sides. My sister began to moan and scream, and my boyfriend almost knocked down the sofa.

I guess the two of them may be trying to squeeze the eel to death. After a while, they stopped moving and sighed greatly. Her boyfriend sat up and confirmed that they had killed the eel. I know it's dead because it hangs there limply. Although my sister and her boyfriend are a little tired because they just finished fighting, they still continue to woo. He hugged her again and kissed her. Eels may have nine lives like cats. At this time, my sister.

The answer is: Eel is her boyfriend's little brother.
