I can certainly imagine it, though. Before you met her, she could barely stand going two hours without a massive, messy orgasm to empty out her hyper-productive balls. They were the size of grapefruit, maybe even bigger, before swelling up with dense, cake-batter thick seed, and even going as long as six hours without cumming was unfathomable.
Now? Well, it's been months since she last reached orgasm. It's not that she's gotten any less productive- if anything, the cabinet full of different supplements more than doubled both the amount and the thickness of her pungent, virile seed. The days of her packing grapefruit-sized balls is long gone; her spunk tanks now rival the size of prize-winning pumpkins, each one so densely and thoroughly packed with her semen that their sheer weight was double what one would expect.
As usual, she was edging herself, driving her colossal spunk factories to work harder and faster than ever. Her toes curled as she rode a hair away from climax, her balls so heavy that they couldn't physically pull up far enough for her to ejaculate with only her tongue- but all that stimulus certainly made her severely blue balls ache and rumble with sheer over-production of seed.
It wouldn't be much longer until her swollen blue balls were as big as the beanbag chair she used to prop herself up, at this rate. You wondered how long she could endure it- how huge her balls could really get. What if she managed to wait long enough for each fat, swollen, cum-packed testicle to get as big as that bean-bag chair? What if she kept going? What if her aching balls screaming for release never managed to overthrow her desire to build up more, swell to larger sizes, and feel the weight of all that gooey sperm compact further and further?
The thought of that was almost more exciting than the new supplements you'd bought her.
