I will call Dark sonic just dark and Sonic at some points. :D
Amy was watching in horror as Sonic was thrown out a window. As he jumped back in to kick Shadows ass Amy jumped in between them. " Stop!" She cried. Shadow growled lightly before punching her into the metal door. " Amy!" Sonic ran to Amy who wasn't moving. " Y-you killed her!" he growled turning a darker blue and his eyes turned all white. Dark Sonic got up and threw Shadow into the wall then walked up to him. " Are you going to kill me faker!?" Shadow asked as Dark walked up to him. But all he did was kiss him!
(Shadow's P.O.V)
I couldn't believe it! My rival kissed me. I didn't mean to but I deepen the kiss.
(Normal)
Shadow had to moan giving the darker one a chance to dart his tongue into his didn't feel anything in the kiss but his body sure did! Shadow groaned in pain. Dark stopped and looked down to see his HUGE erection. " Damn stripes." he purred as roughly claimed the other's lips in a deadlock. Dark Sonic moved from his lips kissing and nipping at his collar bone and continued south. Shadow moaned lightly into this until warmth covered him. Arching, Shadow glanced to see that Dark had taken his erection into his mouth. The ebony hedgehog didn't know what was happening at this point, suddenly, it didn't seem to bother him so much.
Dark continued sucking Shadow, wanting every droplet of pre cum he could get. Shadow ragged breathing meant he would be at his peak soon. So, Sonic stopped, pulling away from Shadow's aching erection. Shadow groaned as the contact disappeared, and decided to look at Sonic to see what he was doing. Dark Sonic looked at Shadow with a smile as he straddled his waist and leaning down kissing him again.
After a minute and the need for air, Sonic departed from Shadow's lips and checked to see if Shadow's erection was moist, or what it looked like to Him. Dark stood upon his knees and aiming for something and this was when Shadow could have swore he moaned loudly. He had a feeling he was going to enjoy this.
Sonic slowly and painfully pushed himself upon Shadow's erection as it filled him, and continued to go down. Sonic moaned, finally swallowing Shadow into his tight ass. Shadow panted as the warmth invaded him, and electric jolts of pleasure was racking his body needing release very badly. However, he knew the dark one needed to adjust. So, he just waited.
Once he felt comfortable, Dark Sonic began to move himself up and down upon Shadow. The ebony hedgehog's eyes widened at this.
"God you…feel so good", Growled Dark as he came down upon Shadow again.
"Your tight as hell", groaned Shadow
Sonic panted heavily as he rode Shadow, this was until Shadow told him to get on all fours. Sonic complied pulling Shadow out of himself to get onto all fours. Shadow got up behind him, inserting himself into Sonic. Sonic gasped at the feeling of being full once again as Shadow began to pound him. Both boys were moaning like crazy. " Shadow you're so good at th-AH!~" Dark screamed as Shadow rambed into his prostate. After a few more thrusts Dark came all over both of them. Shadows nails dug into his hips as he relesed into him. Shadow pulled out and fell to the floor to notice the other one fell asleep so Shadow did too.
