She rubs your manhood through the front of your diaper

You are in the midst of suckling on Ellaria's right breast, and she has her right arm securely wrapped around you. Your attention is focused solely on feeding, whereas Ellaria is focused on the tent in your padding. While you drink her milk, she slowly reaches down, presses her left hand against the front of your diaper, and begins rubbing.

You gasp in surprise, almost leaking milk out of your mouth. Thankfully, Ellaria holds you firmly against her chest, preventing you from unlatching. You gaze up at her apprehensively, and she just grins and tells you "Relax, sweetie. Just keep drinking, and Mummy will give you a little treat."

Since you cannot really protest the situation, you obey her. As Ellaria's sweet, warm milk continues flowing into your mouth, she continues rubbing your padded crotch. Over the next few minutes, her rubbing becomes firmer and faster. At the same time, you increase the pace of your suckling, and you are humping into her hand.

Finally, after five minutes, you hit your peak, and you orgasm into your nappies. At approximately the same time, you drain Ellaria's right breast, and you finally pull away. Ellaria gently lowers you onto the bed, keeping her right arm around your back.

As you ease down from the pleasure you've just received, Ellaria smiles and pats your padded crotch. The front of your diaper is soaked with your cum, while she feels. Ellaria giggles and mutters "Good baby; making a big boy mess in his nappies."

You blush at this, but you find that you like the teasing.
