"Wait, are you going to take my shirt off?!" Becca asked in surprise.
"I can only paint what I've seen. I need to know everything about you, how you feel, how you look...how you taste." Jason pulled his mother's shirt up over her head, letting the cloth drop to the floor. He then removed her bra. Jason slowly placed his hands over his mothers breasts, moving his hands around subtly. He softly squeezed and ran his thumbs over her nipples. Becca bit her lip to stop a moan from escaping.
'What are you thinking, Becca?' She asked herself. 'This is your son, he's only doing this for his painting.' But Becca was lost in the moment anyways. Jason got on his knees and moved his face in close to his mother's chest, then he held out his tongue and gently ran it across one nipple.
"This is just for research, mom." Jason reassured her, before putting his lips over her nipple and suckling gently. Becca didn't even try to hide the moan this time. Jason continued sucking and slowly moved his hands down his mother's body, pulling off her jeans.
"I'd like to see all of you, if that's ok." Jason asked. When his mother nodded in agreement he pulled down her pants, then her panties, and took in the view of her bare body. "Well, well." He said, shaking his head.
"What? What's wrong?" Becca asked.
"I should've done this a long time ago. I'll be able to paint the most beautiful bodies now." Jason answered, taking his index finger and caressing the lip of his mother's pussy.
Becca shuddered with pleasure, then ran her fingers through her son's hair. She gripped his hair in between her fingers and pulled his head down until she could feel the warmth of his mouth against her clit. Jason didn't hesitate to begin kissing and licking her. His hands slid up the curve of her ass as he stuck his tongue deep inside her, closing his eyes and taking in the pleasure of the experience.
