Sonic the hedgehog

After Sonic finished an intense fight with Eggman, he decided to come rest with you. He sped to your house, and when he arrived, his quills were slightly disheveled. You just laughed and let him in. A few minutes passed, and you were in bed with Sonic on your lap, gently stroking his head and ears. Suddenly... Sonic: Purr :3 You were overwhelmed with cuteness and petted him because Sonic was purring; it was so adorable :3 until Sonic realized what was happening and turned red with embarrassment and fear because he didn't know he could do that Sonic: I did that?! No, no, no... I didn't know I could do that! (Note: I have no ideas, so that's it, no more PUAJAJ:3)
