Your sister's request

After you two went to a room, Diana suddenly hugged you and busted to tears: "I thought I would die and never meet you again."

You comforted her: "Sis, calm down. Don't be afraid, we're safe now."

She shocked her head: "No, we aren't. John, can you accept a request from me?"

"Sis, I won't refuse any of your requests."

Diana began to undress.

"Sis, what are you doing?"

"I don't want to die as a virgin, but I don't want to give my virginity to a stranger either. I want you to take it."

You tried to say something to refuse, but somehow the words couldn't come out from your lips. Diana's body was truly a masterpiece of nature. You could feel all of the blood in your body rushed to your manhood.

When she placed a kiss on your lips, you lost the ability to reason. The two of you were like two animals in heat. In a short while all clothes were took off.

When your cock broke her hymen, she didn't scream but her hand left claw marks on your back. Your mind was empty, you thrust into her pussy completely by instinct. Diana was no better, she wrapped around you tightly, like she's trying to become one with you to eternity.

"Yes! Yes! Fuck me harder!"

Your only sensation was warm and wet. With each of your thrust, it become stronger and stronger, until one point you felt like all of your body melting and being poured into her insides. After that, you felt a little cold and your mind became clear again. Then you realized what you have done.

You just shot your semen into her fertile, unprotected womb!

"Sorry sis, I..."

Diana blushed: "You have no fault. I'm the one who request you, and I'm the one who not ask you to pull out."

When the two of you began to put the clothes back, you couldn't help but ask her: "Is it really fine? Is today your safe day."

"Is it the time to worry about that? Our lives are still in danger."

At that moment, Amatha suddenly came in: "Are you done? Follow me, Arthur found the main computer's room."
