Shi has just turned 18 and has given her boyfriend a handjob

Shi has just turned 18 and has given her boyfriend a handjob for the first time. Sadly he came within 5 seconds so she has gone to see the family doctor as he is the only person she can talk to about it. Not only does she want to know what she did wrong, she intends to get some practical tuition! As the doctor protests, she yanks down his pants and starts stroking his big cock. When the young girl takes his dick in her mouth he soon cums all over legs. It seems she is an expert after all!
