She kisses him like a lover

"Kiss me, Mom," Derek repeated, wondering how the changes he'd just made were going to effect his mother, wondering if he'd changed her personality enough for her to willingly push the boundaries of their relationship.

"Mmm, I like the forceful attitude, Derek," Jess almost purrs, stepping in close to him, her eyes shining with excitement as her arms reach around his shoulders, gently pulling his face down to hers. "I've always loved men who knew just what they wanted," she breathes softly, her lips just barely touching his, teasing him with her closeness as she presses her shapely naked body against his. "Especially when what they wanted was me," she giggled, leaning against him more, her mouth pressing against his lips.

The kiss started simply, just their lips meeting, a chaste if not motherly kiss, but it quickly changed, deepening, as Jess pressed her mouth harder against her son's lips, her lips parting, her tongue darting out to flick at his. His hands found her waist, pulling her closer, her ample naked breasts now squashed flat between them as they pressed their bodies together. Her hand moved up his neck, her fingers combing through his hair as her mouth opened wide, her tongue sliding against his as she gyrates her hips into his. Derek's hands slide down his mother's soft hips, fingers gripping, kneading, the soft flesh of her ass, the sensation causing her to moan into his mouth. Needless to say, Derek was hard, his cock bulging out of his pants, prodding his mother in her stomach as she kissed him, her naked body caressing his as their mouths were joined in the most un-maternal way possible.

"Wow, Mom," Derek gasps as the kiss finally ends, his heart racing in his chest and his breath coming in short shallow gasps from the pure passion, the uninhibited lust, that was in their kiss. "That was... that was amazing," he assured her, his hands still resting on her naked ass, his erection hard and throbbing against her stomach.

"Yes, it was, sweety," Jess breathes in contentment, smiling up at her son. "And that was just a hint of what could be," she teases him, thrusting her hips against him suggestively, "but not today. I'm running late for a meeting," Jess tells him with a little frown, stepping out of his embrace. "I've got to get going," she assures him, clearly **** to leave.

I could convince her to stay, to keep going with her, to maybe even have sex, Derek muses, watching his mother's shapely body as she starts to gather her discarded clothing from around the room. But should I?
