<div class="floatleft">(http://orig10.deviantart.net/5ca1/f/2015/070/3/0/raph_by_pixeldust86-d8ld69h.jpg)</div>Raph was more than prepared to rip those sweatpants right off of Casey's muscular body if he had to, but thankfully she was one step ahead of him. With as aroused as he had become though, it was almost torture to have to let her slip away from him for even the time it would take her to slowly pull her pants down. The mesmerizing sight of her rear end made it all the more difficult; perfectly round and full, it made his cock twitch in anticipation. He might have actually tackled her to the ground in excitement, had she not begun to back up into him and prepare to straddle him once more. A long and drawn out groan escaped him as she ground her shapely backside into his manhood, and he allowed her to do as she pleased; enjoying it far too much to stop her as she got into position.<br/><br/>He began groping and squeezing her breasts the instant that she guided his waiting hands into her ample bosom, and physically quivered with lust as Casey rubbed his erection along her pussy. "You're not gonna hear any complaints from me, Jones."  He smirked as the girl leaned back into his sturdy chest, his thick cock throbbing in her grip. With a sister as amorous as Michelangelo, Raphael had learned how to utilize the pull-out method some time ago. He wasn't exactly sure if he even could knock up a human girl like Casey, but it was better to be safe than sorry. There had been times where he had gotten so into it that he had forgotten to pull out before an orgasm...but he would just have to make sure this wasn't one of those times.<br/><br/>Unable to take Casey's teasing any longer, Raph began to push himself upwards inside of her. As he penetrated her warm pussy for the first time, it wasn't long before he was working to bounce her up and down in his lap; sliding his cock in and out of her inner walls as they began to form around his green member.
