Neptune smiled proudly as she looked over her clearly infallible trap she had set up in Big Nep's home. The "infallible trap" was actually just a cardboard box held up by a cardboard tube attatched to a very visible rope. The bait in question was pudding. Hearing someone approaching, Neptune hid in her well crafted cover (read: "pillow fort" and resembled a bunch of pillow placed sloppily on a couch) and waited for her prey to take the bait.

As Big Nep entered the room, she stopped in the doorway as she looked about what had been set up within it. Confusedly, she looked at the cardboard box and the delicious pudding beneath it, then followed the rope connected to the tube that lead all the way to the pillow fort that covered her smaller counterpart. This was a trap, obviously. And a great one too! Foolproof, if Big Nep wasn't, obviously, also Nep, and therefore could see right through the trap that she herself probably would've set up. A mischievous smile curled her lips, as she happily made her way over to the cardboard box, slowly crawling beneath it to get at the pudding underneath... And to prompt Nep to spring the trap exactly as Big Nep wants her to.

Taking the bait that Big Nep set up as a response to Nep's own bait, Neptune pulled the rope and caught a Big Nep. Licking her lips a little, she approached the non-stealthy cardboard box and lifted it up slightly. "I got you, me! Heh, surely I am a master baiter! ...Wait, that came out wrong."

"I think it came out right, actually," Big Nep responded, as she burst out from under the cardboard box as it was lifted. She grabbed her younger self and sent the two of them crashing into the pillow fort, the soft landing sending Nep's head into her adult version's own pillows. "Depends on how you would classify nepping yourself~" She licked the corner of her lips, wiping away the remnants of the pudding she'd devoured in the short time in her trap, the taste still fresh on her tongue.

After a short struggle, Nep pulled her head out of Big Nep's "puddings" and asked, "What do you mean by nepping myse- ooooh. Oh my, how lewd! Hmhmhmhmm!" Welp, that quote from the anime had to appear sometime in this fanfiction. Memes aside, Neptune joked around a bit, completely unaware hat Big Nep meant what she said.

As Neptune giggled to herself and memed to save herself, Big Nep had already begun to strip the girl of her clothes. It didn't take long, really, considering she'd already been prepared to get to the nepping as quickly as possible, while Big Nep herself had already discarded most of the essentials. By the time the CPU finally realized that her older self wasn't joking, she was already too ensnared in the trap, as the older girl reached her hand into the pile of her clothes for a "tool" to use.

A nervous smile grew on Neptune and a generic anime sweat drop formed on her forehead. "Y-You're joking, right?" Nep's eyes quickly glanced over to the hand ruffling through the growing pile of discarded clothing.

"You know we never joke about this~" The smiling expression that stared down at Neptune was anything but the face of mercy, and when Big Nep finally found what she was looking for, it became even less so. From the pile of clothing, emerged a strap-on, two immensely thick, foot-long shafts extending out from the base. "You fell right into my trap, me~" The older Neptune equipped her weapons of choice, before she slowly began to line up the two shafts just right with her other self's lower holes.

Those "weapons" shocked the younger Nep, especially due to the fact that they were about the size that Iris Heart herself used. "T-There's no way those will fit!" The smaller Nep exclaimed.[/quote]

Big Nep had to fight to keep her giggling from getting too loud, remembering the other, much larger insertions (mostly from Plutia) that'd fit before this. "We both know that's not true~" And like that, she was off. The older, more experienced(if you could call it that) Neptune shoved the twin shafts into her own body, the younger one's stomach bulging noticeably right off the bat as she pushed in.

"NEPU!" Mininep let out a surprised moan as the shafts were both fully inserted down to the base so quickly. As the two girl's hips were left together for a few seconds, Neptune took in heavy breaths as she tried recovering from just the first thrust.

After a few moments, Big Nep drew her hips back, slowly pulling out inch after inch of the thick strap-ons. Just before removing the two shafts however, the woman suddenly thrust forward again, right in the middle of Mini Nep's recovery. She quickly pulled back again, then thrust forward, repeatedly thrusting hard into her younger self.

"NepuuUuUuUuUuU...!" Each thrust brought about a raise in pitch in the smaller Nep's voice. Trying to ease herself into the hip-slapping action, Neptune wrapped her arms around the older version of herself to support herself.

Giggling a bit, Big Nep gradually increased her speed, the girls' flesh slapping together louder and louder with the smaller Nep's voice. However, that voice began to grow quieter after a minute, as something began to bury Neptune's face. It didn't take a genius to know what it was; Big Nep's breasts were squishing into Mini Nep's face, reducing her voice to muffled moans.

With two big lumps of boob in her face, Neptune tried to at least embrace the situation, taking one of the breasts into her mouth and gently suckling on it. A quiet moan slipped through a few of Big Nep's giggles as she continued, pounding away as she tried to drive herself closer and closer to her limit. "Starting to enjoy yourself, me?" She asked, mostly rhetorically, as she pushed more and more of her breasts down onto the smaller girl.

At this point, Mini Nep was now practically drowning in boob. Neptune tried answering her older counterpart's question, but was, again, muffled by her breasts. Big Nep was more than okay with this, her soft moans growing steadily louder as her younger counterpart inhaled more of her breasts. Mini Nep's lower holes meanwhile were still being pounded away at, the woman steadily going faster and faster until she started to approach Iris-level speeds.

Trying to show some control despite the fact that Big Nep was slamming into her exponentially faster, Mini Nep moved her right hand and placed it on Big Nep's other breast, and then moved her off hand to place it on Big Nep's sizeable bottom. Then, she followed her placements up with firm squeezes.

Though Big Nep's moans grew louder with each movement of her younger self's hands and each squeeze of her sensitive bits, she still retained the most control over the situation. She even somewhat encouraged what Mini Nep was doing, in her own way, rewarding her counterpart by grinding against her more sensitive areas after each thrust, which grew faster and faster at the same time. It wouldn't be too much longer before Neptune found herself being sent over her limit, by herself no less.

And not much longer it was. Mini Nep's body curled up slightly as her voice echoed into her adult version's breast, her hands clamped down on whatever boingy bits they held, and a flow of love nectar gushed forth from Mini Nep's womanhood.

Big Nep let out a long, low moan through Mini Nep's orgasm, pleasured well enough but her younger version clearly going through exponentially more in this one moment. Giggling to herself, she began to pull out after she let the girl come down from her climax, the thick foot-longs coming out drenched in Neptune's juices. "My, it really is fun playing with myself like this~"
