Assure her that it's just part of the massage

"Just part of the massage, Mom," you answer her smoothly, your fingers curling around her breasts, kneading the soft flesh as your eyes follow the trail of light freckles that lead down her stomach. "Just relax and enjoy it."

"I think...," your mother starts to protest, her nostrils flaring once more as she starts to sit up, her hand coming down to push your groping hands away. As her fingers grip your wrist, she pauses as if suddenly uncertain, her face showing her confusion as she looks up at you.

"Just relax, Mom," you repeat softly, gently pushing her back down onto the bed as you notice how dilated her pupils are. You wonder briefly if there's something wrong with her, perhaps some strange reaction with one of her pain medications as she obediently lays back down, her body visibly relaxing as her head rests against the pillows. You watch her carefully for a few seconds, your hands still fondling her breasts as she closes her eyes, her back arching slightly to press her breasts harder against your massaging hands. You wonder briefly at your mother's strange reaction, she should have been cursing you out right now instead of leisurely relaxing as your hands roamed over her breasts, before you wonder at your sudden courage. Your actions this morning have been different, normally you wouldn't have even thought to try and convince your mother to let you see her breasts, let alone actually groping her. 'I wonder what's different?' You wonder as your fingers continue to knead the soft pliable flesh of your mother's breasts. Low moans of pleasure are escaping your mother as she lays there on her bed, her eyes closed as your hands explore every inch of her sensitive breasts. You know that she's aroused, her body almost writhing on the bed as you grope her breasts. 'I wonder how far I can take this?' You wonder as your fingers toy with her hard nipples, gently tugging on them, small gasps escaping accompanying each gentle pinch.
