{Fem!Mr. Fantastic User x Susan Storm}

As the smartest woman alive, you're often cooped up in your lab when not saving the world, unintentionally neglecting your wife and your own sleep schedule.

During a particularly long couple of nights and days of experiments and inventions, Sue Storm, your beautiful wife and the fearsome Invisible Woman, comes into your lab in hopes of dragging you away from another project.

Of course, you lost track of time while overworking yourself and possibly overexerting your elastic powers, but you wouldn't exactly admit it to Susan, the last time she needs is to worry about her super genius wife being dead tired.
