"I wish that I knew why men act the way they do around women!"
Yukiko smiles. "Your wish shall be granted." Yukiko starts to giggle. "Whats so funn-OH!" She doubled over in a brief feeling in her abdominal area. Kinda like a shifting feeling which faded into a soft tingly pressure. "Wha-what did you do to me?" Naomi yells. "I am currently granting your wish." Yukiko responds.
Naomi ran to the mirror, the feeling in her groin made it feel very weird. She could see that her pajama bottoms were wet. Naomi groaned again as she felt them starting to feel tight and tighter, and her groin began to feel really good.
She became aware of a pushing sliding feeling as her crotch tented slightly. "Oh no!" Naomi squeaked as she realized what was happening. The crotch of her pajamas and panties felt very full. She placed her shaking hand on her growing bulge. "I-is it over?" Naomi asks facing Yukiko.
