A certain mintpone had discovered it was Alvito’s big special day soon, and wanted to give the stallion a special “big” surprise for him. So she would give him such: She would end up putting on a nice special gown, would hide in his bed until the night before his day, and would then puff up and UP as he’d sleep. Until eventually, the stallion would wake up early in the morning to the sight of such a macro-inflated and busty unicorn. With the plans she has for him, being engulfed in tons of rubbery mintpone cleavage was going to be only the start of the fun she had planned for him, as she gave him a look that made clear one thing: She was going to do lewd things to him he didn’t think were possible by the end of his special day…~
