Him & him & him
Its unfortunately lightsaber censored, but its a poly with 3 guys one gal. The relationship is super healthy (I'm talking unheard of levels) and theres lots of smut. Its worth a read in my opinion (short too, only 16 chapters and a few side stories). Btw when I say super healthy i mean it. They immediately stop when she says so, checks with her before going into unknown territory, and established a safe word quickly. Theres also really no jealousy either, but you might be a bit weirded out since the guys are all related (twin brothers plus their uncle). The guys only touch their woman, so it thankfully doesn't have any incesty vibes or scenes. It does kinda start out a bit iffy though since the brothers brought her in somewhat out of concern for their uncles lack of a sex drive/life.
