Completely avoiding the regular argument that orbits around blacked content, I just gotta say, this seems 100% feasible. Luka, particularly the Paradox version of him (of which Sonia, this character, is featured) is such a massive bitch. Getting his childhood friend fucked by someone who isn't a pathetic submissive with a 3-inch dick seems pretty likely. Hell, he'd probably even get off to it.
