Can anyone help me find a BL oneshot?

Does anyone know a BL oneshot where it's in the historical/medieval era and idk I forgot the plot but I'm pretty sure the seme was a prince and uke was a count/his secretary... Or childhood friend? I'm unsure! But I remember a scene where the seme f*cking uke while walking and saw the uke's brother(uke asked for help but the brother just flabbergasted) as the seme walks to their carriage (his pen*s still in uke)
