Tiddie Time!

You quickly mutter the last few words of the spell, your heart pounding in your chest as your brother's hands inch closer to your chest. You feel his hard cock press against you, and it takes every ounce of your concentration not to lose focus.

As you utter the final words of the spell, a wave of energy washes over you. Your brother's hands pause just below your ribs, and you can feel his confusion as he registers the hardness of your chest. You hold your breath, hoping the transformation completes before he can react.

Suddenly, his hands are no longer on hard plastic but on soft, warm flesh. He lets out a low groan, clearly pleased with what he feels. "Mmm, babe, your tits feel so good," he murmurs, his voice thick with desire.

You can feel the weight of them, the sensitivity of new nipples straining against your sweater. It's a surreal sensation, and you have to suppress a gasp of surprise and pleasure.

You can't help but feel a thrill run through you as you realize the spell has worked. Your brother's hands are now groping your sister-in-law's actual breasts, and you can feel every sensation as if it were happening to you. You turn your head slightly to see his face, twisted in pleasure and desire.

"You like that, huh?" you say.
