As she clung tightly onto him, going through her own orgasm, Alex lowered his head until he was face to face with her and forcibly kissed her, pushing his tongue into her mouth and swirling it around.
When he finished cumming Alex broke free of her and pulled out his new demonic cock from her. It's hard was shaped differently then before, more like a horses although Alex couldn't tell, and it had some small spikes sticking out along it's shaft. Even his cum was different, now black just like that of his demon mistress. Alex scooped up a glob still stick to his cock and put it to his mouth tasting it on his tongue.
