Tom Brady's back under center ... in a smoldering beach make out session with his supermodel wife, Gisele!
TB12 loaded up the family and flew to Costa Rica for their annual offseason beach vacation -- where the couple proved they've still got that fire 10 years after they tied the knot!
38-year-old Gisele showed off her legendary physique in a pretty tiny bikini -- while 41-year-old Tom didn't look too bad either!
In fact, Brady looks like he's made some gains in the gym since those infamous dad bod pics from last summer.
