NP: No, you PP are UNDERreacting. The kid is only 9 or 10. Even though OP is more concerned about the inappropriateness of the talk and its effect on her son (which is a legit concern), I read what she said her son is hearing and I'm concerned about what that boy is being exposed to and why a 9 yr old has these graphic images in his mind.
Yes, exploring oneself sexually has often already started by this age, but talking about it a lot and having specific graphic images of sex acts with another person are huge red flags for inappropriate sexual exposure or contact for a child his age.
OP is absolutely right to notify the teacher and the Principal, since some of the kids who are listening to this kid may not all be in the same class. But more than anything, the teacher and Principal should be on the look out for any further signs if age-INappropriate sexual discussion or stories.
