Yes she does. And they're fabulous!

"You shouldn't be thinking about me like that," Jessica announces with a sudden look of disapproval. "I'm your sister, for God's sake!"

Jackson blushed furiously. How...

"I wasn't thinking anything!" he denies.

"I'd never tell you how big my boobs are," his sister continues. "And I sure wouldn't show them to you!"

Jackson was horribly embarrassed that his sister knew what a pervert he was. But then he got a little angry. What right did she have to criticize him, when she was flouncing around like a horny minx, showing off her body, practically begging him to look at her! The little slut had no right to complain! He bet she loved making him hard!

Now it was Jessica who was blushing, then she let loose a nervous giggle.

"I'm just teasing, bro!" she said. "I'm glad you like them!"

She cupped her hands under her tits and presented them to him.

"I know I'm a horny little minx," she confessed. "And I do sooo love to tease that cock of yours! Do you forgive me?"

"Uh...sure, Jessica," Jackson managed. "I'll forgive you..."

"If you show me those titties!" he thought.

"Wanna see my titties?" she asked, and with out waiting for an answer, she shucked off her blue blazer and started on the buttons of her blouse with a big, coquettish grin on her face and frequent happy glances at Jackson's crotch.

"This is so wrong!" Jackson thought.

Jessica's face fell and her hands froze.

"This is wrong," she said.

"No!" Jackson said.

"No, no, no!" he thought. "Show me those titties you bimbo!"

Jessica giggled and continued unbuttoning. Jackson's conscience made one more weak attempt to object and was thoroughly slammed by his insistent libido. No way was he going to think another contrary thing about what was happening. The alien had given him a gift. He accepted that now. It would be rude not to accept such a generous present.

Jessica's blouse hit the floor and moments later, she had released the fleshy twin globes from the bra that held them prisoner.

"Tada!" she explained, sticking out her chest and bouncing them proudly. Jackson stared in wide-eyed delight. She could be a stripper or a porn star with a set like those!

"I think I could be a stripper or a porn star with titties like these!" Jessica exclaimed. "What do you think, Jackson?"
