Learn from her

"Was my kiss really that bad?" Jake asked with concern. "I've only ever kissed one other girl before."

"I've had worse," Emma replied. "But you shouldn't just ram your tongue down my throat!"

"So teach me how to do it properly," Jake said.

"What? You want me to teach you how to make out?"

"And engage in foreplay," Jake added. "When I have sex, I want to make sure my partner is enjoying it too."

"I told you that's crossing a line!" Emma shouted.

"Well, I won the bet and that's what I want to do," Jake replied. "You're not going back on your word, are you?"

His sister hesitated for a moment before finally giving in. "Fine," she muttered. "You have to start off gently, like this." She wrapped her arms around his neck, pulling him towards her. Her lips brushed against his before pulling away, leaving him hungry for more. The next kiss was slightly longer, and Emma allowed his tongue to gently touch hers before pulling away. "Now, rub my back and shoulders to make sure I'm relaxed," she breathed. Soon they were kissing more and more passionately, with their hands roaming all over each other's bodies.

When they finally came up for air, Emma frantically pulled off her shirt and bra. Jake took a moment to take in the sight of his sister completely naked, her breasts rising and falling as she breathed heavily. Then he pushed her onto the bed and grabbed her boobs for the second time that night. Emma placed her hands over his, wordlessly showing him how to move his hands in circles and squeeze them gently.

As Jake continued to play with her breasts, Emma reached down and stroked his cock, an animalistic hunger in her eyes. Jake had lost the condom, but Emma didn't seem to care as she spread her legs and helped him line up his cock to enter her.
