Feeling her tightening around his fingers, he smiles. That's exactly what he was looking for, to hear Alyx moan, that musical tone of desire that resonates and calls out. Slowly wetting a finger as he  uses it to rub her clit, Galen then begins to gently prod at her ass, teasing at first checking her reactions, before plunging the digit into her. Listening for her reaction he continue to pound away at her nethers with his fingers curling inside her, seeking out and exploring her as much as possible. He relentless speeds up as he drives into her pistoning her wet cunt hard and faster than before, pushing her towards her orgasm.
