The Water Ghoul had thought nothing of it at the time: letting the inexperienced little greenhorn Ghoul hang out in his room for the night. Rain had a mindless, funny rom-com on, some girly pop film from the mid-20 aughts playing in the background on his TV while he messed around on his handheld gaming device.
It didn't make any difference to him whether the silly Quint was there at all. He was going to do what he was going to do and no one could stop him. Until those too-innocent words fell out of the rhythm guitarist's mouth.
"Can I touch you a little?" Phantom's fingers were trailing up the back of Rain's sculpted thigh already, the Water Ghoul lying on his stomach on the bed and focused half on his game and half on the movie.
"Sure, Bug, do whatever…" he said with an icy casualness.
What the leggy bassist hadn't accounted for was those nimble fingers tugging down his skimpy sleep shorts over the firm globes of his ass, kneading and spreading his cheeks apart. He could feel the heat of Phantom's body between his legs as the Quintessence Ghoul lowered his mouth to the bassist's already-slick hole.
Rain was in a constant state of "readiness" given his element, but having Phantom breathing and spreading and licking over his puckered hole already made his head spin. He tried to shrug off his growing arousal; the spreading patch of excitement making his shorts stick to his stiffening cock.
The bassist did his best to ignore that talented tongue. He thought that he'd have to walk the Quint through every little fucking thing for their first time, but here Phantom was, eating his ass like it was a god damn buffet right out of the gate.
Rain's voice caught against his fangs for just a moment as he intoned lazily, “Oh, wow, Bug, that’s great.” But Phantom just dug his claws in and buried his face deeper between the bassist's rounded cheeks. Rain wouldn't deny that he loved the attention; he just couldn't believe that the inexperienced rhythm guitarist—who kept flubbing his chords during practice—would be such a hungry little ass eater.
The Quint's tongue was soon joined by his thumbs, spreading and plunging into Rain's—overused but still tight—channel. The Water Ghoul let his game go on without him for a moment, losing his head at the feeling of Phantom's plunging tongue sliding slick and drooling across his sweet pucker.
Rain spread his legs a bit wider, his mouth no longer dripping useless words. He was getting harder by the second, arching his hips back against Phantom's licking mouth. But the rhythm guitarist gave as good as he got, pulling away teasingly just as the Water Ghoul was finally getting into it.
The bassist heard the. whispered shick of Phantom's pajama bottoms, his own pulled off too, but not before a very audible sniff and sigh echoed behind him.
"Dirty boy," the Water Ghoul tossed over his shoulder with a smirk, tail draped invitingly over his hip as Rain felt those fingers clench his waist. Phantom rubbed himself between the bassist's cheeks with a little whimper, their mingled excitement smearing over Rain's fluttering hole.
He hadn't even planned on playing today; the moon had been waning recently, which always affected his sex drive, but it was never completely absent. He was a Water Ghoul after all; always ready for a quickie if the situation presented him with a willing participant; and Phantom seemed plenty willing.
"You gonna put it in me, moonbeam?" Rain's voice was light and teasing, still a bit frigid towards the one Ghoul he saw as needing to have his hand held through everything topside, but Phantom leaned over him with one hand by his hip, steadying his shaft with the other.
The Quintessence Ghoul sucked in a shaky breath as he breached the bassist's fluttering, slippery walls. Rain shifted as his muscles eased apart for the rhythm guitarist's length, loosing a contented purr as Phantom slowly bottomed out inside of him. The rhythm guitarist's shaft was slim and perfect, filling him up just enough to make it hard to breathe.
Rain chuckled, wiggling his ass and clenching his channel just to hear Phantom groan above him. This was going to be easy. The ruffled Quint eased out and plunged back in, Rain's game and the low movie completely forgotten as he clenched the sheets in bemused fingers, groaning in spite of himself as Phantom started a deep, stately pace.
"You can fuck me as hard as you want, starlight," Rain teased, gasping as the rhythm guitarist's fingers found the curve of his throat, pressing his fingertips against the Water Ghoul's fluttering gills. Phantom crouched over his back, breathing hot in his ear as his hips stuttered forward harder, rising to the prissy Water Ghoul's blatant challenge.
Phantom's lips found the curve of Rain's shoulder, leaving soft, worshipful kisses against his blue-tinged skin. The bassist smiled at how adorable Phantom was; how eager he seemed to get his dick wet. The Quint's tail was thumping the bed in time with his thrusts, a wet, messy squelch between their bodies as Rain keened, those fingers slipping further into his flaring gills.
The pressure against Rain's throat tightened as the Quint tugged against his neck, making him arch his back and changing the angle deliciously. Phantom continued to drive into him, his cock kicking greedily against the Water Ghoul's vice-like walls. Rain's head was fuzzy, pleasure suffusing to every shuddering extremity as the Quint plowed his pert backside.
"Ha-aah-Phant-" Rain gurgled out, the Quint's barely-calloused fingertips still massaging just inside his frilled gills. Everything seemed to be creating a perfect storm for the overwhelmed Water Ghoul: Phantom's jutting, insistent cock, those damp lips dragging along his shoulder so sensually, the insistent press of those fingers into his second-most sensitive spot.
"You gonna come for me? My pretty little fishy?" The rhythm guitarist's words were husky, commanding; just the way Rain loved being talked to in bed. Had Phantom communed with anyone before embarking on this salacious bed adventure? Swiss? Aether? How on earth did the Quint know every single one of the Water Ghoul's soft spots?
Phantom's hips bucked against Rain's supple backside, plowing into the bassist like a machine. He could feel the electricity between their bodies, the roar of his own blood in his ears as his stomach swooped and clenched deliciously. He was on the edge of his peak already? How?
Rain's cock pulsed, trapped between his lower abdomen and the bed, smearing his hip with silvery pleasure as his arousal built to a breaking point, with Phantom fucking into him so good it was making him dizzy. The Water Ghoul's moans were jagged and high, groaning on every thrust as the rhythm guitarist fucked him into the mattress.
Rain had thought that his cheeky demeanor could hold out against the "innocent" onslaught of the Quint's sexual advances, but Rain was soon whimpering and whining like he was in heat, desperate to spill hands free against the sheets if only to feel the rhythm guitarist's spill coating his walls. He wanted to feel Phantom explode inside of him; to give him what he craved more than anything.
"Guurgh! Oh- gonna-!" The bassist shivered in the Quint's strong grip, clenching his fingers as he felt his cock kick, coming hard against the slick-stained sheets. Rain keened as he felt sharp teeth digging into his muscled shoulder, ramping up his lust even further as Phantom spilled inside of him with a muffled groan.
"Ngh! Fuck, Rainy, feels so good!" The rhythm guitarist whined as he emptied himself deep into the Water Ghoul's slick channel. Phantom collapsed against the bassist as they both finished, now sweaty and spent, pulling his slippery fingers free from Rain's softly fluttering gills. The Water Ghoul stretched himself against the sheets, the damp spread of his cooling excitement smearing against his mottled skin.
"That was…" the bassist panted, breathless with disbelief at how mind-blowing the last few minutes had been. He still couldn't believe that this was how it had all played out. Phantom's tail was a dull happy thump against the mattress as he nuzzled Rain's slightly sweaty back, breathing in the sweet scent of their coupling on the Water Ghoul's skin.
Rain loosed a contented purr, clenching down on the Quint's softening cock—not wanting to give up this delicious feeling of fullness just yet. The movie's credits were rolling by this point and the bassist's own tail twined with the Quintessence Ghoul's. Phantom released his own soft purr as the Water Ghoul reached for the remote, tossed carelessly to the side of the bed.
"You up for another movie, starlight?" Rain's tone was much softer now that he'd come, post-nut clarity and all that.
"As long as you don't expect me to pay much attention to it," Phantom chuckled, his flagging erection stirring back to life inside the Water Ghoul's slippery channel.
