Ironhide (top, red stallion) and Chromia (bottom, blue mare) making out on a table cloth at a picnic at a park or something. I guess picnics are the best time to make out.

And yes, sorry to ruin things but Chromia is taken. Her and Ironhide are a couple in my canonical alternate universe.

And oh, happy Valentine's Day.

But one thing is for certain, Chromia and Ironhide are not heterosexual, they're LGBTQ. Chromia is bi and Ironhide is pansexual. All my characters in my AU are supporters of LGBTQ.
