Sans moaned louder as his urge to mate increased, "B-Boss... P-please... Don't t-tease me..." Papyrus grinned, pressing his boot against Sans' forming boner. He whipped at it and enjoyed Sans' pleased moans. He even leaned forward and licked his neck. "You taste like cherries.... My favorite flavor... I wonder what else tastes like that... Hehehe..." Sans blushed and barely held on. "B-Boss...." With a smile of pleasure, Papyrus began unbuckling his and sans' pants, pulling them both off. He stroked around Sans' cock and got a few licks on it and his neck. "What a good pet you are. Stay still and I won't have to use force, alright?"

Sans blushed and pinched Papyrus, "B-But I want it.... P-please? I've been a bad b-boy..." Papyrus grunted and took his belt from his pants. He then proceeded to tie Sans' arms up, letting him hang by his wrists. "Now you'll be easier to fuck..." He pressed his pelvis to Sans, making him groan and plead. After a good 30 minutes of teasing, Papyrus positioned Sans onto all fours and began to slide inside him. "O-oooooh.... You're t-tight.... Yeah..." Sans made a silenced gasp of pain and pleasure before being thrust into. "A-Ah... P-P-Papy...." Papyrus cracked his whip again, "BOSS, boss... Not Papyrus, Boss..." Sans winced with lust and laid on his chest. "M-Mmmmmmmm...."

After their long moment of incest, the brothers laid side by side in the bed. Sans had fallen fast asleep right after, leaving Papyrus to be the only one awake. He studied his brother and traced all the scars he inflicted upon him. To his surprise, he shed a few tears. He thought he had lost all emotions after their father mysteriously disappeared from mere existence. He shivered and pulled Sans a bit closer, a fuzzy feeling blossoming within his soul. He finally understood what it meant. Love; Papyrus had found his one and only true Love. He didn't expect it to be his own brother, but at the time, he didn't even care.
