She blows you.

You lunge towards Amber and kiss her again. As you kiss her, your hands reach for her breasts and squeeze them firmly. Amber lets out a moan of pleasure muffled by your lips. You break off that kiss and bury your face into her breasts. She moans loudly as you suck on her left breast and play with her right with your hands. If she wanted, she could suffocate you with her huge tits and you would die a happy man. From her moans, it is obvious she is enjoying your ministrations to her breasts.

After several minutes of licking, sucking and gently nibbling on Amber's tits she steps away from you, removing her breasts from your hungry mouth. Seeing the disappointed look on your face, she says six words which instantly brightened you up.

"I want you in my mouth!"

You barely nod and she gets onto her knees, facing your cock at eye level. She takes your rock hard cock in her hands, rubbing the shaft. As you look down at her, she gives you a dirty wink and then takes you deep into her mouth.

You moan loudly as she begins to suck your cock. You marvel at the fact that she managed to fit all of your eight inch cock into her mouth. You barely resist the urge to grab her head and fuck her face. Instead, you just stand there with trembling knees as your gorgeous step-sister gives you the best blowjob of your life.
