The sun shined in a cloudless sky on what seemed like a normal day at Vanilla's residence. After playing hide and seek with Cheese for a couple of hours, Cream was now resting peacefully on the living room couch. Meanwhile, Vanilla was searching through the kitchen, mildly frustrated. She looked everywhere, but it appears that she's missing most of the ingredients for the cake she planned on baking. Sonic was coming over, and Vanilla was hoping to provide him a nice meal as thanks for recently helping her daughter out of trouble again. Now it seems she has to go to the store to do that.
The mother rabbit's thoughts were interrupted by the sudden sound of the doorbell. She answered, knowing who it would be. Sure enough, Sonic waited on the other side, he gave her a wave. "Sonic, its great to see you." Vanilla greeted with a smile. "Glad to be here. I can't wait to have some cake." he said. 
"Well, about that..." she started
"what's wrong?"
"Well, I forgot that I used up most of the ingredients baking cupcakes a few days ago. Now I have to go to the store. Since the usual market is closed today, I have to go into town, and that trip will take awhile."
"I can make that trip in no time" Sonic offered
"No no, I'll do it. You deserve to enjoy yourself while you're here. Just keep Cream company while I go out."
"Well, if you insist." Sonic said as he entered the house. Vanilla grabbed her purse and exited the door. "snacks are in the pantry, I know Cream will be happy to see you. Just play with her until I get back. You'll get that cake, I promise." Vanilla closed the door behind her.
Despite the snacks, it didn't take long for Sonic to get bored. Cream was asleep and Cheese was nowhere to be found, probably in chao kindergarten. Sonic walked around, which seemed like the only thing he could do. He than looked at Cream, who seemed very serene in her rest. She was always so adorable, he was always more than happy to save her life. Looking at her now, Sonic couldn't help but notice how...attractive she was for her age. He smirked as indecent thoughts entered his mind, perhaps there was something he could do for fun after all.
He got near her, and didn't hesitate as he brushed a hand on one of her legs. Her soft fur felt lovely, in fact, her whole body looked as soft as a pillow. The thought excited him, the anticipation made his monstrous shaft begin to slowly lengthen and harden as he proceeded to carefully take off her shoes, than her socks. He slid off her panties with one hand while the other lifted her skirt and caressed her soft upper body.
Unfortunately, as careful as he was, Cream still stirred from what he was doing. She slowly opened her eyes in time to see him finish removing her panties. "M-Mr. Sonic?" she squeaked in confusion.
Sonic reacted quickly. He pinned her down by the shoulders as his cock, now fully erect, tore into her virgin pussy. Cream screamed in pain as she felt her hymen tear apart, robbing her of her sexual innocence. Sonic wasted now time pounding the scared little rabbit, his erect penis was so thick, it made a visible bump on her mid section as he penetrated her. It seemed as though he couldn't fit his whole girth inside of Cream's small vaginal passage, but that didn't stop him from trying.
Cream couldn't speak. She could only scream, gasp, moan, and breath heavily as tears streamed from her eyes. She was unable to comprehend her situation. Cream was scared, traumatized, in pain. Yet she also felt all of it mix with intense sexual pleasure.
Sonic was in ecstasy. He knew this was wrong. He's supposed to be a hero, but he was forcing himself on to her, and she was so much younger than him, but all of this only aroused him more. It was all horribly wrong, and he loved it. Sonic groaned as he felt himself about reach his pent up orgasm. He yelled and Cream shrieked as he unleashed his hot seed into her underaged womb. He filled her to the brim, and than beyond capacity, splashing a mess on the couch.
After that was done, he sank his weight on top of her. they laid on the couch, silent as they caught their breath. Sonic was the first to speak.
"Oh Cream, your pussy is the best I ever had." He complimented. Sonic looked her in the eyes as she stared at him in confusion, disbelief, and fear. "M-mom! Mommy!" she screamed as she tried to scramble away from him. Sonic just pinned her down again, he was stronger, and definitely faster, she could never escape. "It's just you and me here right now Cream" He explained, stroking his throbbing manhood. It hadn't softened at the least, still dribbling cum.
Suddenly, he turned her whole body around and bent her over on the arm rest of the couch. "You were feeling good too, I can tell. You liked what I did to you huh?" Cream shook her head in denial.
Sonic chuckled, "I think you want more, I know I do."
Cream felt his cock head push against her nether lips. "No!"
Sonic just grinned as he shoved his whole girth back in. Cream yelled out one last time before she realized how futile any resistance would be. Defeated, she stayed quiet as the blue hero completely had his way with her. It went on for what felt like hours, his reserves of cum seemed endless, every orgasm was just as messy as the first. After multiple climaxes Cream was desperately trying to catch her breath, her senses were dull at this point. She barely registered Sonic talking to her. "Still got one more left in me." He said before grabbing the sides of her head and stuffing Cream's mouth full of his manhood. Now that it was in her mouth she could really feel the heat coming off of it. It felt hot before, but now, it was too much. Cream could taste the mixture of both their fluids as it reached deep into her throat.
"No gagging huh? Your a natural at this!" Sonic didn't waste time raping Cream's face. The size of his shaft stretched her throat. "Oh yeah, that's right, Breathe through your nose. You were meant for this, a natural born slut." He picked up the pace, thrusting faster, Cream offered no resistant. In truth, she was also surprised she was swallowing his cock so easily, she just let instinct take over. Cream felt something thick and hot flood her throat as Sonic climaxed inside of her mouth, the taste of his seed was indescribable.  Cream coughed up cum when he pulled out, his dick finally going soft. With no energy left, the exhausted rabbit fell over. There was a satisfied smile on Sonic's face as he cleaned up everything, including Cream herself. After he dressed her back up in clean clothes, he whispered in her ear. 
"Don't tell your mom about this okay? You did a very bad and naughty thing with me today, She'll be mad at you if she finds out. You don't want that right?" Cream was too mentally exhausted to disagree. Vanilla returned home later. The rest of the day was pleasant with the mother being none the wiser.
Sonic's new relationship with Cream continued from that day onward. He would take any opportunity to catch her when no one was around. Everytime they were alone he would molest and rape her. Sonic was pleased when he started to notice that he was fitting more and more of his cock into her as time went on, but that wasn't the only change.
 Cream slowly began to learn and understand sex. At first, she tried to stay mentally resistant, tried to hate what was happening to her. However, as it continued, her reluctance started fading. Soon she started becoming moist from anticipation. During the many times that Sonic jammed his rod down her throat, Cream started using her tongue, and actively sucking him off, much to his surprise.
Days  turned to weeks, than months, and than years. Cream got older, and with age came growth, curves, breasts, and a sex drive that was enlarged thanks to Sonic's treatment. She was becoming hornier, soon she started coming to Sonic rather than him coming to her. She knew that her own lust and the immense pleasure he offered was now consuming her, but she couldn't resist anymore. She began to notice how wonderful it was that his cock was so huge, she started to love how big it was.  It wasn't just the lust though, as she got older, she couldn't help but start to notice Sonic as a man. She started to notice how handsome he was, how charming he was, how intense yet gentle his soothing green eyes were. Most of all though, she remembered how he had saved and protected her in the past from danger, and had no doubt in her mind he would still do that for her. In fact, it felt like he would do that for her now more than ever. He was still a hero, the greatest hero, women could only wish to be with him, and she had him all to herself.
Sonic went through his own changes as well. He was pleased at how Cream's body had developed over the years. She was fast on her way toward becoming as curvaceous and well endowed as her mother. However, like Cream, something other than lust also grew in him. She would always be cute, but as she grew, Sonic started to notice how beautiful she was, especially her eyes, he started to have sex in positions where they could look at each other more often, so he could look into them. He loved staring into her lust dazed expression as she took pleasure in what he did to her. Sonic started to treat her more nicely, he was now more gentle and even more caring while still remaining dominant over her. He was even giving her gifts and going on dates with her now.
At the end of one such date, Sonic was having sex with her as usual. Cream was on her back with Sonic on top of her, thrusting viciously. He could fit his entire girth into her now, and Cream's inner walls clenched and squeezed happily. She squealed with joy and Sonic groaned in ecstasy as they both climaxed together. They silently took time to catch their breath, Cream was the first to break the silence. 
"I love you, Mr. Sonic." Sonic was surprised when Cream suddenly pulled his head toward her's and pressed their lips together in a deep kiss. Sonic returned her affection, sticking his tongue deep into her mouth. Their tongues touched, danced and licked each other as the two of them savored the sweet taste of each other. After it was done, Sonic pulled away from her, a strand of saliva briefly connected their mouths. "I'll always be all yours." she declared. Sonic gave her a cocky smirk, but his expression was much warmer than when he used to rape her. "Heh, that's right. You're all mine." he paused for a moment "Love you to, babe." Cream pulled him back in for another kiss, and they proceeded to passionately make love for a long while. It may have all started off as horrible rape, but she didn't care anymore. It was so much more easy to forgive that by this point, she already did.
A couple of more years have passed since than, Cream was now in the middle of her teens. She was now Sonic's obedient, personal slut. He was her master and she belonged entirely to him. That was howthey both liked it, nothing could make Cream happier.
