Excuse to Smoke

Two teens had been lovers for a few weeks, but the boy was always after the girl to quit smoking. One afternoon, she lit up after some love making, and he said:

- You really ought to quit.

She, getting tired of his nagging, said:

- I really enjoy a good cigarette after sex.

He replied:

- But they stunt your growth. She asked if he ever smoked, and he replied that he had never.

Smiling and lifting her gaze to his groin, she said:

- So, what's your excuse then?
