Rias Gremory yawned as she opened her bleary eyes. She rolled and saw it was still the middle of the night. Rias was still sleepy and smacked her lips as she felt a bit parched. She'd get a glass of water before heading back to bed. She gently got out of bed so as not to disturb Gobugobu and stumbled to her feet.
Rias stretched and walked to her dresser. She poured a glass of water from the nearby pitcher and downed the refreshing liquid. With a pleased sigh, she padded back to her bed. She then blinked owlishly as she noticed the blankets forming a tent around Gobugobu's lower body.
What was that?
She carefully peeled the blankets off of him, and she stared wide-eyed at the pillar of green flesh attached to Gobu's crotch! It bobbed in the cool night air almost hypnotically. Rias gulped as she stared at it. Was it supposed to look like that? It looked like it hurt with how it throbbed occasionally.
Rias reached out with her small hands and touched the pulsing green length. She marveled at how hot it felt in her hands. It felt weird she thought, being both ridiculously hard yet pliant as she massaged the pulsing meat. It was fun, though! It twitched and pulsed like a living thing so it proved amusing to watch how it reacted. She did notice her hands had grown slick from a sticky fluid that leaked from the pulsing purplish tip. Her now slicked hands made funny noises as she played with the weird fleshy appendage.
Rias giggled at how it swelled when she tightened her grip slightly. The veins distended, and the tip squirted more of the sticky clear fluid! Rias licked her lips as a stream of liquid leaked from the bulbous tip. She was still a bit thirsty, after all.
Rias got a great big dollop of the liquid on her finger and stuck it in her mouth. She then shivered as a pleasant feeling ran through her body the second the liquid touched her tongue. Rias sucked on her finger and, after a moment, pulled it out her mouth, disappointed as the flavor disappeared.
Rias' eyes then zeroed in on the source of the delicious flavor. Rias scooted over and nearly straddled Gobu she then gripped the pulsing green pillar of flesh. She gulped and lowered her mouth onto the pulsing purple crown. The second her lips encircled the pulsing crown, she let out a low moan as pleasant heat filled her body. She lapped up the tasty fluid for a few minutes… and that's when she felt the shafts throbbing intensify. Without warning, her mouth was filled with something even more tasty. It was thick and jelly-like and, more importantly, tasted super good! Her mind became muddled as she tried her very best to swallow it all down, but some still spilled from her lips and dripped down her face. The smell of it made her heady. After a moment the purple head popped loose from her mouth as it finished spurting. Her cheeks still bulged from the thick white liquid filling her mouth. She steadily gulped it down and, once she was finished, let out a satisfied huff. She was so full!
She licked up the remnants of the tasty liquid and cleaned herself up in her bathroom. She then plopped down into the bed and cuddled Gobugobu, entering a blissful sleep, tummy nice and full.

Over the passing weeks, Rias continued to get tasty treats from Gobu in the middle of the night whenever she woke up. That white stuff made a great midnight snack! As the weeks went on, his thing kept getting bigger, and his treats were getting thicker and thicker! So much so it was like eating pudding at times! He didn't seem to notice at all, so it would be her little secret. The tasty treats were all hers! He always hogged Mama's milk so it was only fair she got his!
Her lessons continued, and Betty even dropped by to teach her some magic! The blonde girl, not even taller than her, taught her a few tricks she could do with Gobu. Betty's smile sure was wide when she taught her how to share Gobu's senses. Rias just thought it was funny to see how big things looked from Gobu's perspective. Her Mama looked super big! Although Gobu's eyes did focus on her Mama's… boobies a lot. Rias did the same because she always felt thirsty looking at them. Gobu probably felt the same. He always loved milk time.
She shared his senses a lot when she learned how to do it. So much he didn't even notice when she did! That's how she found out he got private milk time! She would have been mad, but she had her own secret treat time, so it was fair.
One day, Rias finished her lessons early and decided to see what Gobugobu was up to. He should still be with Grayfia Nee-chan. She sat in her room and giggled to herself as he learned from Grayfia Nee-chan. She was super good at teaching. Rias knew from experience. It was funny watching her teach little kid things as her face and voice were so serious as she went over such simple topics.
Soon enough, they finished, and before Rias could cut the connection, Grayfia Nee-chan dropped Gobu's pants! She then started to tug on his thingy!
Grayfia Nee-chan had treat time too!
Rias thought it was weird she took pictures and stuff but Grayfia Nee-chan was funny like that sometimes. Like when she always insisted she was a maid even when she was Oni-sama's wife. But Rias still loved her weird sister-in-law.
Rias felt a little funny watching Grayfia Nee-chan rub Gobu's thingy. Gobu seemed to really, really like it. His little noises and grunts filled her ears as if they were her own. Rias felt warm and decided to open the connection a little more so she could feel what he felt.
She then immediately bit her lip as she felt super good. She felt pleasant tingles from a phantom organ. She squirmed in her bed as her young mind was assaulted by alien pleasures. Her fingers reached for the phantom organ but caught only air; they went lower, and Rias shivered as she touched her special place.
She rubbed it, and the pleasant feelings doubled. It was almost overwhelming as she felt Grayfia Nee-chan's soft gloves on her phantom shaft. Squeezing and rubbing in just the right ways to send tingles down her spine. One hand cradled the small green orbs beneath Gobu's pulsing pillar of flesh, and Rias moaned.
Soon enough, Grayfia Nee-chan's hand accelerated, and Rias felt something building up. Gobu's shaft throbbed in a familiar way, and Rias let out a loud moan of pleasure as her phantom shaft pulsed in time with Gobu's. He shot rope after rope of thick white jelly onto Grayfia Nee-chan's waiting hand.
Rias panted as her body spasmed and her mind swam from the duel-pleasured release she just experienced. She soon pulled her hand out of her pants to find it covered in her own juices. She brought it to her mouth and suckled on the slick fingers. It wasn't quite as tasty as Gobu's, but it was still nice.
That felt really good. She wondered if Grayfia Nee-chan did that for Gobu every day. She would have to work hard to get out of her lessons early… but if she got to feel that, then it would be worth it.
She had to show this to Sona when she came over next time! It felt super good, so it shouldn't be wrong.
But first, she had to ask Betty if there was a way to share her senses with another person. She wanted Sona to feel just like she did. Her best friend deserved the best, after all!
