The Box - Sonadow Fanfiction

Not Forever, Just For Now

"You can't do that!" Sonic gasped as he pulled his hand away from his neck, a trickle of blood on his finger, "you can't just bite me!"
"Can't I?" Shadow breathed, pressing himself closer to the thin neck he loved to kiss, inching towards it with sharp teeth ready to indulge.
"Is- is this happening again? That thing that happened?" Sonic scrunched his chin down to his chest to close the gap Shadow was aiming for.
"Don't do that." Shadow raised his arm and grabbed at Sonic's head, pulling him back aggressively and quickly taking the opportunity to nibble at him, only it wasn't so much as a nibble as it was an entire feast.
"Ugh-ow-ahh-" Sonic shook, a familiar shock ran down his body and he slapped his legs shut, knowing this wasn't a smart idea.
With drool dribbling down his chin, Shadow hoisted himself up and forced back open his lovers thighs.
"You're smarter than this, aren't you?"
He got himself nicely positioned and looked down at Sonic's cock, which was erect and seemed to have its own heartbeat, "that was awful quick, don't you think?"
Sonic flushed, "no- wh- what about you!"
"Hmm? What about me?" Shadow watched as blue eyes stared down at him, expecting the worst, "you're not hard?" Sonic wriggled, a little bit embarrassed.
"No, you want me to be?"
He got his reply in the form of a weak nod.
"Then do something about it."
Shadow leaned back on his legs, his hands in the sand and his hips as forward as he could make them.
Sonic wasn't opposed to a challenge, so he earnestly repositioned himself and leaned down, taking the hand that wasn't supporting him and gently brushing Shadows inner thigh, the larger hedgehog chuckled and groaned simultaneously.
Soon, fingertips were just barely touching Shadows nuts, which seemed to do the job as his staff began to quickly grow in length.
"I guess you're just as bad.." Sonic giggled.
"No, actually," the black hedgehog viciously twisted his counterpart so that Sonic was face in the sand, trying to dig his way out, "I'm way worse." He spat down onto the tight hole and aligned himself.
"Wait- that's not enough!"
"Are you forgetting something?" Shadow rammed himself all the way in, "you're a bitch now, this hole was already dripping."
Sonic gasped and melted, this sensation would never get old, and although Shadow didn't usually speak like this, he felt himself get harder as the tip of his cock leaked.
Shadow thrust over and over, clenching onto the blue waist so tightly bruises were bound to form, he revelled in the animalistic noises his counterpart was making, gasping for a moment of peace.
"You crave my cock, don't you? You always like to wiggle and protest but once it touches that slutty hole of yours you turn into a little blue fleshlight designed just for me!" Shadow grunted and smacked his body down as hard as he could, as though his goal was to skewer his lover.
"Sh-Shadow! Fuck!" Sonic was doing his best to stifle screams but pain was mixing with pleasure at an alarming rate as claws started digging into his waist and piercing the skin beneath his fur.
"Pl-please! Ugh- it hurts!" He called, but the thrusting didn't stop.
"Does it, baby? Does it hurt?" Shadow teased, licking his lips.
"Ahhhhh - YES!" Sonic let out a noise he had never made before; one so unlike him he momentarily thought he left his own body.
"Shit- fuck!" Shadow grunted and pushed himself all the way inside Sonic, filling him entirely with the first load of the evening. He slowly pulled out and watched as white liquid dribbled from the hole he had just destroyed.
"Hey, can't let that happen!" He quickly pressed a thumb back into to stop the spillage.
Sonic let his body fall into the sand and spun around, he pried at Shadows hand, "no! You have to let it out, it can't stay there!" He lacked the strength to actually remove Shadows thumb, and his ears fell to his head as his counterpart started to laugh deep from his chest.
"What are you talking about? How can I let it all out? I gave it to you special."
Sonic rapidly shook his head and started to struggle again, "what? No! No, Shadow you know this is bad we shouldn't have done this!"
Shadow- hand still in place- fell onto Sonic and pressed their foreheads together, "you don't understand my love, this is the what we were gifted!"
"Gifted?"
Shadow gently kissed Sonic's nose and then smiled menacingly at him, "and I have so much more to give!"
He quickly removed his hands from the throbbing hole and lined his tip back into position, thrusting back inside before Sonic could say anything.
"Ugh! Ahh! No! This isn't you! We need to go see- uh- we need to go see- mmmf-" The smaller ones voice trailed off as that familiar sensation erased all his critical thinking ability and was replaced with cries and moans begging for more.
After all, if it was with Shadow, he was okay.
