Trying to fit in

A man goes to the pharmacy to buy a condom. At the counter, the female pharmacist asks him what his size is. The man is amazed that condoms come in sizes and answers, “I don’t know my size. Will you help me?” The woman asks the man to go at the back of the pharmacy in the sofa. The woman lies down on the sofa as the man, confused at the situation, takes off his shorts and inserts his penis in the woman’s pussy. “Size B,” the woman answers. “Okay, take it out. How many condoms would you like?” The man asks for two and goes home. Feeling ecstatic over what just happened, he tells the good news to his friend. His friend could not believe so he goes to the pharmacy to try it out himself.The friend tells the female pharmacist that he does not know what his size is, so she assists him to the back of the pharmacy and asks him to insert his penis in her pussy. “Size C, okay?” the woman says. “Now take it out.” The man refuses to take it out, and instead fucks the woman until he comes. The woman then asks, “Wait, wait, how many are you buying?” “I’m not buying one,” says the man. “I just came in for fitting.”
