Their response comes out as a confession that warms Ivy up from his ears, right down to his chest, and down to his stomach, bringing up a smile that's not quite fitting for the moment they're in, let alone the position River found in front of him.
"Yes, you are," Ivy exhales, although he's feeling completely breathless at the sight of them: the morning sun peaking through the curtains, hitting the peaks and valleys of their face, unlike anything he has ever been able to imagine. It hits him, then, that even though he's always been attracted to River in every single sense of the word, it's been running deeper than that for quite some time without him even noticing. Maybe he has been waiting for them to take the first step, or perhaps, some part of him thought this could never be a good ideaβ that he was protecting River by putting all these thoughts in the back of his head, but it becomes impossible to keep up as he looks down at their chocolate brown eyes, that seem to melt with the sun hitting directly into them and a heat that's coming from within. The same heat that's burning at the very bottom of his stomach, slowly reaching his heart, which seems to forget how to function properly every other second.
His eyes soften as he tilts his head, a hand gently landing on their cheek, his thumb moving sensually down the middle of their upper lip and landing softly on their tongue, and pushing into their mouth. "Open wideβ" Ivy whispers, and it's not an order, but there's a kick of power that rises up his chest at the idea of having River do as he says. His cock twitches, and he has to breathe in sharply, only for his exhale to become a moan as he grabs his member with his other hand and gently places himself on the tip of their tongue, not quite pushing. Still, his hips twitch forward instinctively, and it's all it takes for him to know this will be unforgettable. The heat surrounding him elicits a full-body reaction, his lower back arching slightly as his hand moves to the back of their head for support. "That's itβ good boyβ holy fuck," he pants, unable to look away from their eyes.
