Iris carefully examined April’s nipples. “So these are highly erogenous zones despite not being connected to genitalia, correct?”

“Pretty much.” April considered her words. “What counts as an ‘erogenous zone’ kinda varies from person to person, all it means is that you can get sexual pleasure from being touched there. Some people are just more sensitive than others in all sorts of areas.”

A chill ran over her as Iris traced her fingers across April’s chest. “And in your case, your arousal from here is magnified to a greater degree than the average mortal, correct?”

April shuddered from the sensation. “Y-yeah, I’m definitely an exception. My nips were super sensitive even before I started hormone therapy, and that made it way more extreme.”

Iris increased her movements, pressing down on each of April's nipples. Her fingers shifted into a sucker-like shape, forming a vacuum around them and pulling each of the nipples outwards. “And so when experiencing something such as this, it is enough for you to reach your sexual climax?”

“Ah! Not-not quite.” April’s breaths were growing heavy under Iris’s ministrations. “I’ve tried a fair bit, but I’ve never been able to cum from nipple play alone. It always needs something else.”

“But you’ve never tried with one such as myself, have you.” Beneath the suckers, a pair of tiny tongues began licking April’s nipples, teasing them even further. “Would you like to test how far you are capable of getting with only stimulation to this region?”

Although her first instinct was to decline, April had to admit she was curious. She did consider herself a woman of science, after all. And what was the point of science if not to explore the unknown? Such as if a being from outside of reality was good enough at nipple play to make her cum? 

“You know what? Sure, go nuts. Let’s see if we can- ooooooh!”

April’s voice trailed off into a drooling mess as the sensations intensified. The pleasure was racing through her body, yet still fully condensed on her chest, bringing them to a new level of intensity she had never felt before.

She figured that even if she didn’t cum the experiment would still be considered a success.
