An offer he can't refuse

"Wow, maybe you do like me," she commented when Ted gave her a hungry look. "Just let me know if you want to see the girls," she said, then turned to talk to her father.

"Well sure, let's see em," Ted couldn't help but say.

Without stopping her conversation with Grant, Jade reached up and slid the straps of her dress off her shoulder. She shimmed the dress down, bunching it around her waist, letting everyone see her bra-clad breasts. They were large; not as big as her mother's, but high and firm, which made them look larger anyway. After a few seconds, she reached between them and unhooked the bra, shrugging her shoulders to slide the bra down her arms, and put it on the table. Her breasts hadn't fallen almost at all with the removal of the bra. Ted stared at them hungrily as his sister and father kept on talking as if nothing was odd about her casually pulling down her top and baring herself.

"Yeah, I kinda figured," was his mom's only comment to the side as she saw him transfixed by his twin's tits, completely matter-of-factually.

Ted felt a bit bad about that. "Hey mom, how about another sex lesson?" he asked, turning his attention back to her. Jade made no move to cover herself.

"Sure," Amanda said, as if he had just asked her for a hand with this homework. She moved over to him and made as if to sit on his lap, grabbing his dick to guide it into her again.

"Let's try something a little different," Ted said, stopping her. She looked at him curiously for a second, and he guided her to get down on her knees in front of him. Realizing what he intended, Amanda adjusted her grip on his cock and leaned forward.

"More sex lessons with mom?" Jade asked in a teasing tone of voice.

"Now now, your brother can have all the sex he wants, lessons or not," Grant commented.

"Nice stiffy bro," Jade teased as she looked on. Amanda gave his dick a slow lick along the underside, then stroked him a few times, making Ted moan. After a few strokes, she opened her mouth and put him inside. It was nothing like fucking her; a completely different experience. Her tongue wrapped around him, caressing his length in her hot mouth, and the feeling of suction was new. She sucked hard, cheeks bowing inwards.

And then she stopped and pulled off of him, looking up into his eyes. "I doubt you will ever need it, but this can help you get going if you are having trouble," she commented as she stroked him lightly, the she took him back into her mouth.

"That looks so weird in real life," Jade put in. "I know the guy likes it, but how is it for you?" she asked curiously.

"Well, oral sex is mostly about making the other person feel good," her mother replied after pulling off Ted's dick again.

"Doesn't seem like much of lesson, since all he has to do is sit there while you do all the work," Jade commented.
