They're both lost to the physicality of it for a bit. Essek is near euphoric as he's made to take more of that long, thick, hot length into the tight, slick clutch of his cunt, and his small body gradually adjusts to allow it. What arouses him most about the process of working himself up to accepting his alpha's cock is the big paw gripping his hips, ensuring that he can't squirm away. Taking more is his only option, and so he does.

Essek has never been so loud in bed before. Whimpers and gasps are punched out of him with nearly every little thrust, and by the time Percival speaks into his mind, more than half of his impressive cock buried in the vicelike grip of his omega's cunt. The short rocking motions and the wide stretch at his entrance and the constant rubbing against the incredibly sensitive front wall have Essek on a precipice already, head spinning. He can't possibly speak aloud right now and be understood.

I have never felt anything like this. The thought comes through clearer than words would. Don't stop. I need you, alpha, yes, like that--

Even that deteriorates as a tremor passes through Essek's body, pleasure peaking sharply and cunt squeezing. This orgasm comes with a soft whine and a needy roll of his hips, welcoming more of his husband's cock and milking every inch inside him.
