After saving her from the nihilego, you were called over to help with therapy which lead you to this situation, the toxins from the ultra beast did something to her body and is driving her into heat, semen is what's keeping her at bay but semen isn't the main problem it's she needs to fuck and nobody can satisfy her and smelling her pheromones is what sets the male off, luckily the aether foundation gave you an endurance serum

She Approaches you and notices your hard on, she talks about your virginity and she surprised to see how big you were (it was your natural size) aaaand then they fucked like animals.
but not before she 69ing each other to get a better wif of each other then you proceded to "scissor straddle" her (idk that's what that position is called but every position is ends with a creampie) then clapped her bubble butt cheeks doggystyle then mating pressing her while sucking her breasts till you finished with one big ass nut in her like you were trying to get her pregnant which resulted in you being her go to guy till the cure was made and had a fuck buddy.
