Chapter Text
Belphegor's body gives a sudden jolt when Astrophel pushes in slowly, trying to not hurt the demon. Their breath becomes heavy as they squirm to get more comfortable." Stay still ,will you?" Astrophel whispers next to their ear, pushing in deeper, giving Belphegor time to adjust.
"S-sorry..-It's so hot and just..so hard to breath..-" Belphegor arch their back when Astrophel is finally deep in them, trying to keep their breathing steady as Astrophel presses kisses all over their face and body, helping the demon to calm down.
"The heat is unbearable isn't it?" Astrophel starts to move after some time, making Belphegor jolts.
"A-Astrophel..~" Belphegor calls out through their tears, their body twitching at some places.
"Shhh ..Relax. .I'm here ..Let the heat submerge you sweetie ..I will take care of it" Astrophel kisses Belphegor's tears away, thrusting much faster causing Belphegor to moan louder.
"So good.. So warm and so tight.." Astrophel groans when she feels Belphie tighten around her.
"Sweetie.. You're tightening around me.." Astrophel strokes Belphegor's cheek gently, calming the demon down as they purr.
Mhm~ That's a good whore~" Astrophel lets out a suggestive chuckle as she speeds up causing Belphegor to gasp and arch their back. Belphegor grips the sheets tightly as Astrophel thrusts into them relentlessly, causing them to cry out in pleasure, muffling their sounds with a pillow near them.
"Such a…" Astrophel lets out a growl as she thrusts into Belphegor hard and fast. "Such a good whore..~" Astrophel captures Belphegor into a kiss, wrapping their legs around her waist, helping her reach deeper into them.
"A good whore deserves rewards don't they?~" Astrophel coos as she feels Belphegor scratching her back, leaving finger marks on her skin.
"P-Please!-I'm s-so close!~" Belphegor begs desperately, feeling themselves so close to release.
"Well.. since you asked so desperately.. Then." Astrophel gives them a sharp thrust. "Cum." Belphegor let out a cry of pleasure as they came onto their stomach and Astrophel's chest. They drop down onto the bed, panting heavily.
"Look at the mess you made…So dirty.." Astrophel chuckles as she resumes to her original pace, thrusting into Belphegor as she chases her own release.
"Hah..-Ah!~W-Wait.. Little star!~" Belphegor gasps when Astrophel starts to move again. Taking the advantage of them being sensitive after their release to overstimulate Belphegor.
"L-Little star!~" The demon cries out as they feel like coming for the second time.
" Hm?~What is it sweetie?~" Astrophel coos as she takes a sniff of Belphegor's scent, the smell of sweetness filling Astrophel's nostril, a comforting smell. Astrophel pulls Belphegor into another kiss, swallowing the demon's moans as she gives Belphegor one last thrust and comes into them.
"F-Fuck ..Sorry. I shouldn't do that .l-" Astrophel got cut off when Belphie wraps their arms around Astrophel's shoulders, pulling her into a kiss.
"Don't just fucking apologize after we just make love Astrophel.." Belphegor groans in annoyance when they pull apart.
"Alright alright sweetie..Noted" Astrophel hums happily as she pulls out, her semen leaking out of Belphegor and she collapses on Belphegor, content.
"Astrophel ..Remember.. Marking.. thing.-" Belphegor reminds the goat demon as they are still overstimulated from their love making.
"It's a tradition isn't it?" Belphegor nods and Astrophel hums. "Alright alright." Astrophel finds a spot on Belphegor's neck to make the mark visible to everyone before biting down, causing Belphegor to let out a gasp as their body twitches. Astrophel bites down hard into the skin, making it break and starts to bleed out as she releases Belphegor's neck.
"Is that good enough?" She grins at the panting demon below her.
"Y-Yes.. More than good enough.." The demon shakily replies.
"Great! Cause we might need another round soon sweetie" Astrophel chuckles when she notices Belphegor is hard again.
"Just.. get on with it already.." Belphegor blushes furiously as they look away.
"Gladly~" Astrophel coos as she slides back in and again, she starts to thrust into the one and only Avatar of Sloth.
☆EPILOG☆
"Belphie ? Sweetie? You good?" Astrophel wakes Belphegor up with her soothing voice, a bit of concerned in her tone.
"It's…aching ..Sore..-" Belphegor replies sleepily, they wince slightly as they feel a sharp pain when they try to move.
"Don't move yet!-You're gonna hurt yourselves more!-" Astrophel quickly pulls Belphegor back onto the bed, hugging Belphegor close to her. Belphegor lets out a noise of annoyance but quickly shut up as drowsiness starts to take over them again.
"Sleep sweetie.. It's okay.. I'm here.." Astrophel whispers sweetly to Belphegor, holding the demon close to her as she examines the marks she marked on Belphegor yesterday.
"They don't hurt do they?" Astrophel askes as her hand rests on the visible mark she bit them yesterday.
"No.. not at all.." Belphegor hums as they snuggles closer to Astrophel making the goat demon chuckles.
"If you say so.." Astrophel sighs, patting Belphegor on the head.
"Mmm…Goodnight little star.." Belphegor murmurs as they close their eyes and drowns into a comfy slumber.
"Goodnight sweetie.. You did well yesterday." Astrophel hugs Belphegor close and kisses them on the cheek before also drowning into a comfy slumber, feeling more content than ever.
