Charlie didn't quite know what to do, but judging by her expressions he knew he wanted to make his mother happy. He longed for a deep connection with her and got that when he fed, snuggled, and kissed her, but of late he wanted more. he looked in her eyes, at her flushed face, the soft moans elicited by his hands.  "You're so beautiful momma." he stroked her side, across her belly,  then gripped her erection, stroking it a few times all while gauging her reactions. He could watch her face and touch her all day and never tire. When his hand, now even stickier returned between her thighs, he pushed further, pressing a finger just inside her.
