Part 2, continuing where part 1 ended. It might be a while before I get time to continue again, but didn't want to leave Amy hanging!
*****
James and Amy held each other tightly, relinquishing the soft kiss finally, and just holding tight. He was reeling from the moments before, trying to process what had just happened. The boldness of his sister in law was not something he could have ever imagined, and the memory of how incredible her sucking his cock felt was keeping him somewhat aroused. Amy slowly gyrating her pantied crotch against him was not hurting either. He stroked the back of her neck and tilted her head to kiss her again. She probed again with her soft tongue, James tucking away the knowledge that she must really like that. His hands lowered down along her hips and then around for the first time to her shapely ass, squeezing her cheeks hard and pulling her tightly against him.
Amy moaned into his mouth as she felt the tip of his cock mashed against her. She was beyond turned on, and everything that was happening was adding to her lusty needs. Her nipples grazing against James' chest felt like little tingly little sparks that found their way to her burning pussy, and she tried to move to get his cock pressed near her clit. She tried to suck his tongue into her mouth, and was a bit surprised when he broke the kiss and turned her around facing away from him. He had one hand on her stomach and the other she felt fumbling around near her bottom, then felt him pulling his semi-erection up and pressing it's length against her. He pulled her backward, pressing between her ass cheeks, and she started to slowly move up and down grinding against him.
James' hands were rubbing her body now, fingertips dragging slowly up her stomach and across the underside of her slightly sagging breasts, grazing her rock hard nipples. Up slowly to the nape of her neck, caressing behind her earlobes. She pushed her ass harder against him, reaching back to pull his hips and trying to nestle his cock deeper into her crack. His fingertips were making their way back down, softly brushing the sides of her breasts, then pushing them firmly together. She felt his hot breath on her neck and shivered when she felt his tongue licking up to her earlobe, taking it between his lips...her tingling nipples in his fingers now, pinching, pulling. Amy let go of James' hip and started to move one hand to her neglected mound. She made it to the top of her panties, but as she started to press downward toward her aching clit, his hand covered hers and pulled it away.
"No" he whispered, "that's for me."
Amy cooed softly, and moved her hand up to her breast, squeezing hard as she felt his fingers trace over her swollen cuntlips, moving downward until he was cupping her full mound in his hand. He felt the hotness radiating from her sex, and began squeezing her fleshy mound through her panties, pressing his middle finger firmly until he felt her panty slipping into her hot slit. Kissing her neck, he stroked slowly and firmly up and down, pressing deeper into her and watched as she brought both hands to her heaving breasts, pinching and twisting her nipples hard. Amy moved her hips up and down between his cock and his finger.
"oh yes!" His finger pressed into her lips, putting pressure on her swollen clit. He felt the little nub, and focused there, pressing his finger firmly against her and letting her move and rub against him. Amy spread her feet a little, arching her back as she ground into his cock. She was getting closer, breath catching as she rocked against his probing finger. So close...
