Ai accepts, and sucks at writing smut. So, we add conditions including "write like George R. R. Martin" and use "show don't tell" and after attempt 3 we get this:

Jake approached the bed with a primal hunger in his eyes. The two women lay there, writhing and moaning as they explored each other's bodies. He watched for a moment, his nostrils flaring as the scent of their arousal filled his nose. The werewolf stepped closer, his powerful form looming over the women. One of them looked up at him, her eyes wide with lust and excitement. The other one simply moaned, lost in her own pleasure. Jake growled deep in his chest, his eyes locked on the two women. He could feel his own arousal building, a fierce need driving him forward. With a snarl, he pounced onto the bed, landing between them. The women giggled and gasped as he nuzzled their necks, his rough tongue caressing their skin. They tangled their fingers in his fur, holding him close as he explored their bodies. He nipped at their flesh, drawing small gasps of pleasure from them both.
