Inaho is obsessed/has a thing for Slaine now to the point that he jerks off to him Slaine still has a thing for the Princess Before Slaine turns into Count Slaine Inaho randomly runs into Slaine, gets his chance and rapes him? 3P if there's a sequel
Base +7, indefinable -1, PrussiaxAustria +6, Inuyan +4
99% sure it's all Inaho's fantasy for how he subconsiously wants it to go down. iirc this book was planned/published way early in cour2, before Slaine became a Count.
