We present a 2-D hydrodynamical model of the colliding circumstellar bubbles of two stars (25 M⊙ and 40 M⊙ respectively) during the main sequence. Placed approximately 16 pc apart, each star initially creates its own circumstellar bubble as the stellar wind sweeps up the ambient medium. Eventually, the two bubbles collide and merge as the swept up shells fracture upon collision. The remnants of the colliding shells are pushed toward the star with the weaker wind.
