Grateful

"Lexi" You smile " You are the best sister in the damned word. But stop this game. You don't really want me."

"I do!" She tries to protest.

"Sis, I know you too well to believe that. I know that you are keeping your virginity for a future husband, and I respect you for that. And you offer what you value most, just to make your loser brother happy."

"You are not a loser! That's just what all sluts around don't see, that my brother is the best man around!" She protests once more "Don't be a saint! At least not now, bang your hot virgin sister before she changes her mind! You deserve some action. You have done so many good things for me, renting my twat to you is the least I can offer back."

"Lexi, don't use such language or your strict older brother will punish you." You joke "Dirty words don't suit my little sister. Now let's stop talking about this, we can't fuck. That's just wrong and you know it."

"Yes but... You deserve more than peaking on your sister's friends" She lowered her head " And should you ever change your mind, I am always ready to spread my sexy legs for you, John"

"I won't change my mind. Now, please, leave me alone, I have a little problem to handle." You point at your boner.

Lexi giggles "Sure, want a little hand action? What will you imagine? Or rather... who?" She gives you a naughty little wink.
