    Summary

    It was one thing when Peter and Harley presented within the same week. It became a whole other issue when the bloodwork had shown Harley to also be enhanced. It was only a matter of time until the coupling cycle hit one of them, which would probably sympathy-kick the other one.

    Peter heated. Harley didn’t rut. Peter heated again. Harley didn’t rut. Peter heated again; they were caught by KAREN, dry humping on the loading dock, and when Harley finally hit his rut, all the symptoms of Killian’s serum hit too. It took three betas, two robots, a dildo, and a fire extinguisher to calm that mess down.

    So it was with bated breath that Bruce checked them both. Peter’s cortisol, Harley’s alphasterone, his own blood pressure, Tony’s plan-b supply, he checked it all. He sighed with relief to see a successful insertion. "Okay, looks good down here. I'm going to sit back, keep watch, you keep up the good work."

    Harley nodded, sifting fingers through Peter's hair and planting his feet to fuck up into him. There was a bit more steadiness now, a kernel of certainty, as Harley became comfortable with the heat, found a way to hold onto himself just enough to let go.
