He isn't expecting to be dragged up against Astarion's chest. Fenris nearly chokes on his breath as the angle changes and his head nearly falls back against the other elf's shoulder as sharp teeth nip at his ear. The sound of Astarion's desperate breathing is unexpectedly intense and Fenris reaches back to get a hand in Astarion's pale hair now that he's been deprived of grass to grip.

"Yes," he pants, voice heavy as a hand wraps around his, the new touch electric. Fenris arches his back and he trusts Astarion to stay grounded as he fucks him and drives him toward his end. "Fuck--"

Sometimes the common tongue is best for cursing. Tension rolls through his body and he tries not to cry out (and fails, miserably) as Astarion's intense attention finishes him. His cock pulses against their palms, come smattering over his stomach and their joined hands. He goes tight around the hard length buried in him, dizzy with how it feels to be fucked through this. Muscles tremble and the hand in Astarion's hair tightens as he tries to resist the urge to curl forward, to give in to that feeling.
