I just read this and did I bookmark it!!  No!!!!   In it, Sam gets Dean to admit that he has lusted for him for 7 years and so Sam begins c**kblocking Dean 7 times (once for each year) before letting Dean orgasm.  At the end, they are cuddling and Dean gives Sam a vicious pinch and says "One".    Then there is something about a resultant black eye!!   Any help appreciated.  

Thank you.
