Huh. So that's what my girl has been attempting on me from time to time. Only she likes taking my cum too much for it to really last more than a fuck session or a day, using it to either build up a larger load for herself or to leave me wanting more from her later in one of her sexy schemes. And the only time it lasted longer than that, after a couple days, I couldn't stand it anymore, found something on the internet to enjoy and spoiled all her work when she finally 'let' me cum a few days later just to check on my progress. She was hoping for a massive load and was very disappointed and confused by the more normal dosage I gave her, until I explained what happened. She hasn't attempted longer than a day since.
