Keeping up the mental link, but moving closer to the bed so the other room's occupants couldn't hear them, "I don't think she's a demon, either. Again." If Lucia's goal was to spread corruption, a handjob wasn't going to cut it. Even if she was refusing penetrative sex to avoid draw attention to herself, a blowjob would be more effective without being any more suspicious - even a demon's saliva was corruptive, though obviously to a lesser degree than their blood or sexual fluids.
With the goings on next door, Astra couldn't help but feel her own pent-uppedness much more keenly than before. Perhaps it was time to make a move of her own. Focusing her powers inward, she pumped up her breasts, hips and ass to the point where they strained her dress without risk of tearing it, and grew her cock and balls back out - her arousal causing it to already be half-hard and tenting her dress. Lying on the bed at Alex's side, her best assets facing towards him, she whispered seductively in his ear, "Why should they have all the fun?" With no prior knowledge of his sexuality, this was a bigger risk than she'd normally take, but she was desperate for sex; if he wasn't receptive, hopefully he'd just dismiss her words and enhanced body as the product of his cider-addled mind.
