Yes

His aunt Gwen pouted a little and sighed.
"Oh fine! But you better know what your getting in!" she teased as she picked up her bags, gave him a childish peck on the forehead and walked away, leaving a little embarrassed Donk with Jill. As he turned around he could see her struggling not to laugh as she looked him in the face.
"She's certainly something" Jill giggled softly, her blush fading as the Donkey faced most of the embarrassment. However this only caused Donk to feel sillier.
"Y-yeah... Um... s-see you round" he stuttered as he walked out of the store without another word, bag of underwear in his hand.

By the time he had gotten back to his dorm he had calmed down a bit and locked the door. He had yet to fully try on his new underwear so wanted a good look before he wore it publicly even if no one was meant to see it. He stripped down to knowing and blushed at his small member which looked at him back in the mirror. The idea that his aunt would have shown off his child sized ween, which had only grown slightly since then filled him with dread. He opened up the bag and pulled out the underwear and took a proper look at them for the first time. Like before they were white with baby blue stitching and he even noticed now a blue waste band! They almost looked like tighie whities but smaller! He couldn't help but blush more as he felt the soft material they were made out of. A soft twitching downstairs confirmed he enjoyed them, from the look, feel... to the fact Jill had hand made them... Before he knew it his little guy was at its full 3 inches and he had yet to try them on! He took hold of there sides and slipped them up his slender legs, pulling them tightly across his small package and to his shock he was able to make a tent in them! Normal underwear left him looking like a woman even with a boner but these were so tight he made a tiny tent. It had to be able 1 to 1.5 inches of a tent but it was huge to the Donkey. He smirked but then there was a knock at the door!
