Jake holds off a bit longer

Although Jake desperately wanted to feel Emma's pussy clenching around his throbbing cock, he still hesitated. To be honest, he was a bit scared, with it being his first time. He couldn't measure up to her many more experienced clients; in fact, he probably wouldn't last five seconds before cumming!

Instead, Jake shifted over slightly, replacing his cock with two fingers which he promptly pushed into her pussy. "W-what are you doing?" Emma stammered in surprise.

"You're teaching me about foreplay, remember?" Jake said. "I haven't finished exploring your beautiful body." He kissed her neck, his lips making their way down to her breasts, all the while his fingers plunged in and out of her pussy.

"Ahh... d-don't say that!" Emma gasped.

Jake realized that his sister had been called hot and sexy numerous times, but no one ever really called her beautiful before. "But you are beautiful," he whispered before leaning down and sucking on her breast. Emma moaned and grabbed the sides of his head, her body thrashing beneath him like a fish out of water. Suddenly she bit her lower lip barely suppressing a scream and Jake felt something wet gush past his fingers.

"W-what just happened?" Jake asked, sitting up and pulling out his fingers, now soaked in her juices.

Emma lay back on the bed, breathing heavily. "Y-you just made me cum," she muttered in awe, her cheeks turning pink.

Jake stared into his sister's eyes as he brought his fingers to his mouth, making her blush even more. "It's delicious!" Jake exclaimed after sucking on his fingers. Immediately he dove down between her legs, taking a few moments to kiss and lick her thigh before eagerly eating her out. Emma's sensual moans were music to his ears and it wasn't long before she reached another intense orgasm, this time not even trying to hide her scream of ecstasy.
