Claudia's sing-song voice would usually calm Callum down, but as her lips and mouth vibrated around him, the now-adult prince found it more and more difficult to keep his desires at bay. His girlfriend had the same problem; she'd love to continue her oral caresses, perhaps just to test how long can she tease him until he'd give in and ram his cock into her mouth, and spill himself into her belly. As the years went by, she indulged more and more in one her favourite fetish, but sadly, today she knew she will have to end it prematurely.
His trembling knees and legs, as well as his quickened breathing gave her the signal to end the first phase of their date night. She looked up at him, their eyes met, and the divine sight of Claudia in her revealing lingerie, sitting between his legs in the most submissive of poses pushed him over the edge, but she was already prepared for it. In a split of a second, she let go of him and substituted her mouth with a vial, at the same moment when Callum cried her name, emptying his lungs, as well as his balls.
Claudia couldn't help but marvel at the voluminous streams of thick, white liquid hitting the bottom of the glass and mixing with the rest of the ingredients. With her hand on his manhood, she made sure that she milked him of all of young, virile cum. Not because the contraceptive potion needed it - just one drop of one's lover would have sufficed - but ever since the two crossed the borders of intimacy Claudia seemed to have develop a peculiar appetite for her younger boyfriend's seed, which improved the potion's taste magnificently.
She capped the bottle with her thumb, shook it a few times, watching as the liquid inside mixes, and she proceeded to give Callum one last, and the most erotic part of their foreplay. She stuck her tongue out and tilted the vile, letting the gooey, thick mixture drip into her mouth. The same moans that a moment ago drove Callum to his edge now escaped her throat again, this time joined with unmistakable, guttural murmurs of satisfaction when Callum's familiar taste and smell reached her palate.
When the very last drop of the mixture landed on her tongue, Claudia leaned and showed her lover the liquid collected in her mouth, swished her tongue back and fourth a few times, and in one go gulped down the salty, musky and potent drink, which ironically would ensure he would be able to spill as much of himself inside her without any consequences. Claudia hopped onto the bed, and was not surprised to see that her magic worked again, and Callum was ready to give her a taste of his.
