One Piece: Ero Saiyan

NOTE: This is my first time writing a smut CH. Thought it'd be easy but damn..it's way more messed up than writing a normal chapter.

enjoy!

Peter then lay atop her, contemplating his next move. Though he had taken the initiative, Peter seemed unusually inexperienced. 

Fortunately, this was also Robin's first time attending such an "event," making them evenly matched - neither could criticize the other. 

As their hips collided, Peter took charge, pressing himself against her body. With some sweet words, he began his performance. 

"Has anyone ever told you how enchanting you look up close?" Peter's hand moved to her face, caressing it slowly before a finger traced her lips, feeling their soft texture and rosy-red hue. He lifted her chin with his other fingers for a full view. 

The raised chin revealed her collarbones and beads of nervous sweat glistening on flushed skin - her cheeks, ears, and neck all tinged red. 

'I should've escaped when I had the chance,' Robin cursed inwardly at her predicament. 

"Ah~" The electric sensation from his dominant touches only intensified Robin's growing warmth. 

Recognizing the crucial moment, Peter brought his lips to hers - starting gently before aggressively sucking her lower lip. 

This only aroused Robin further, who began actively kissing back, their lips cleaning each other. 

After a minute of lip play, Robin parted her lips for air - an opportunity Peter seized, his tongue exploring deeper. 

One hand descended to her chest, kneading and rubbing slowly while the other toyed with her ear, which Peter found oddly soothing. 

"Mmm," Robin moaned from the excessive stimulation. 'Damn...I'll go crazy if this continues.' Not to be outdone, Robin reached for Peter's chest, massaging his muscles. 

As their tongues dueled, Peter's hand left her ear, traveling down to slip beneath her panties. 

'God, I must resist tasting this nectar.' As his fingers slid under her underwear, they met warm wetness, playing with her clit and juices. 

"Ahh...I think something's coming from below!" Robin gasped, breaking their saliva strand as she pulled away. 

Peter knew she was close and accelerated his movements, finishing with a pinch to her clit. 

"I'm c-coming!!" Robin's floodgates burst like a waterfall into Peter's hand - which didn't help as he immediately licked it clean. 'What can I say? I couldn't resist.' 

"Tastes like salty pineapple," Peter remarked, watching Robin's face turn crimson at his action. 

"Y-you idiot! Why would you do that?!" Humiliated, Robin wished the ground would swallow her. 

"Haha...just curious. Don't mind it - let's continue." He turned to her chest, ripping her shirt to reveal a black bra. "Mmm...good taste!" Lifting it exposed milky-white breasts with pink nipples. 

'I once saw a documentary saying nipple color matches...down there.' Snapping from his reverie, he eagerly attacked her chest, sucking, biting, and teasing her nipples. 

'I'll get my revenge...' Robin, experiencing her first orgasm from a man, wasn't idle - her hands immediately found the bulge in Peter's pants, stroking it rhythmically. 

"Mmm...! Didn't expect this move from you!" Peter shuddered at the sudden assault. 

"Don't underestimate me because I'm a virgin. Remember, I'm a researcher - I know more than you ever will," Robin said between heavy breaths. 

Losing control, Peter swiftly removed their remaining clothes, flipping Robin into the famous 69 position. 

He stared at her dripping pink folds. 

"Ah-!" 

Robin's sudden, unexpected moan of pleasure sent tingles through Peter's ears. 

"What...what did you just - ah~!" 

"Hehe...just a little stimulation." 

"AAAAH!" 

The overwhelming pleasure completely consumed Robin. 

"S-stop! If you keep going...I'm coming!!!" She collapsed onto his legs, lustfully eyeing his already 9-inch member. 

[Note: Average in One Piece is 180-190cm tall; 6 inches would be generous for most.] 

After recovering, she curiously approached it - her first real-life view versus textbooks. With Peter's encouragement, she took charge, stroking, kissing, and licking along its length before carefully sucking, warned not to use teeth. 

"Robin, prepare to receive my children!" Peter came in her mouth, which she dutifully accepted without spilling a drop. 

Swallowing, she grimaced. "The taste is awful, and my jaw hurts from the pounding." 

After a brief rest and exchanging pleasantries, they returned to the main event. 

"Well, time for the train to explore the new tunnel," Peter lifted her, positioning his cock at her entrance with slow teasing. 

"Mmm..." Robin moaned, joking weakly, "Hope the driver's qualified and didn't bribe his license." 

"Haha...we'll see his skills soon. Hope you remember those words." Their dirty jokes strangely bridged some emotional gap - though physically exposed, their hearts remained distant. 

"Wait...!" Peter paused at her entrance when Robin spoke. "This feels odd given our situation, but...what's your name?" 

"Peter. Call me Peter." He laughed inwardly. 'At least she'll have a name to moan.' 

As his member pressed through her vaginal walls, it finally met her hymen, which he didn't hesitate to break. 

After gentle kisses and ear nibbles, Robin asked him to continue as the pain faded. 

They shifted positions multiple times, Peter grinding against her. 

"AAAHH!! Peter! I'm coming!" Robin's fragmented moans were interrupted by Peter:

"Me too - let's come together." Seconds later, they collapsed onto the bed, embracing in quiet relaxation. 

"Wow! That was more exhausting than I thought," Peter said while gently wiping Robin down, who teased, "Saying that like it's your first time." 

"It was." Robin sat up, staring in shock. 

Peter mocked her reaction, frowning. "What? Didn't you enjoy it eventually?" 

"No, that's not - I'm just amazed how you forced me with that stern face when it was your first time." Peter waved dismissively.

"Who said I forced you? You didn't resist, and I didn't want to embarrass you by refusing." 

With a strange look and mild disgust, she snorted, "Hmph! Hypocrite," before lying back down. 

... 

The tent finally fell into brief silence. 

But soon, Peter awoke energetically, declaring it time to "plant seeds" again. 

Robin had no choice but to comply - if she couldn't resist, she might as well enjoy it. 

In the blink of an eye, the sky darkened, the sun set, and the world fell into darkness.
