There's a lot that is uncertain for Tighnari still but with this he can be resourceful and it's not exactly a hardship to him either. He moans into the kiss, tongue sliding against Dorrek's as he arches into him, pressing his body flush against the other's as he continues to rock against the other's thigh, working himself up and the movements perhaps do have the added benefit of letting him rub against the other's crotch in subtle strokes.
