The next couple times that Charity went to visit Jeremy he would either lay her down and fuck her with her legs spread -- sometimes wrapped around his waist, other times with one or both over his shoulders -- until he got her off, and then he'd cum in her mouth or on her tits. She didn't know why he liked to cum on her tits, but she liked to try and catch the spurts of white froth in her mouth, plus it saved her from having to wipe the sticky stuff off of her flesh. And every time he'd play with her asshole, pushing one and then two of his fat dark fingers into her back hole as he ate her out or she rode him. By now she was used to it when he would push his fingers into her tight ass, it even felt good to have that extra sensation of something opening up her tight little asshole.
Still it made her a little nervous when she returned to the clearing and he wanted to do something new.
"Get on all fours," he told her. Chastity did so, getting on her hands and knees and looking up at him expectantly. His cock was hard and ready, that thick black girth that she had come to adore so much... her mouth watered with the desire to suck on it. Instead, Jeremy walked around behind her... she trembled at his touch as his hands caressed her ass, pulling her cheeks apart so that he could look at her little asshole. Would today be the day that he put his big black cock up her ass?
"Soon," he whispered, answering her question as his thumb circled around her asshole. Chastity moaned a little, pushing her ass at him...
His hands began roaming over her back and her ass, squeezing at her flesh. Chastity moaned, especially when his hands came around to her front and began squeezing her breasts. Looking down she could see his dark hands kneading the tender mounds, playing with her nipples, and she shuddered with erotic pleasure at the sight of his dark skin pressing against her pale flesh. Jeremy pressed into her from behind, his dick rubbing along the length of her wet pussy, making her yearn for him to turn her over and spread her thighs open for him.
Instead, he pulled one of his hands away from her breast in order to line himself up with her pussy, and he began to push into her from behind. Chastity gasped with this novel sensation as his dick rubbed the insides of her pussy in a completely new way. Jeremy pushed into her from behind, all the way until his groin met up with her ass cheeks, she could feel her ass pressing against his body and it made her moan and wiggle as she luxuriated in this new self-indulgence.
Then he pulled out and slammed in again, taking her breath away and rocking her body... she found it required much more effort to keep herself up on her hands and knees than it did to lay on her back and spread her legs. It also bothered her that she couldn't see him fucking her now... but at the same time she really liked the way she felt completely in his control in this position. His hands moved around and started kneading her breasts again, making her moan as she pushed back against him.
With every thrust, she could feel her elbows buckling a little more, and her wrists were starting to hurt and she didn't like how that distracted her from the pleasure she was getting from being fucked from behind. So she lowered herself to her elbows, which had the pleasant effect of making her ass high in the air while she was in a better position to be on the receiving end of Jeremy's thrusts.
