Tanya

“Sis, I like to have a look at your chest now,” you said. “If you could please remove your dress and bra.”

Tanya did so almost eagerly, undressing and throwing the clothes over her shoulder in one motion.

She was such a perfect mix of seductiveness and innocence.

Once her shirt and bra were off, she looked a little unsure of herself.

"Am I... ugly?"

You smiled to calm her, "You're beautiful as a goddess".

To make her feel better, you leaned over and started to massage her big tits.

She moaned as you touched your sensitive breast area: "Oh oh oh, you make me feel strange... do you like my breast?"

"Yours is one of the greatest pairs I've ever seen."

She noticed your choices of words: "'One of'? What pair is your favorite one?"

"Mother, obliviously."

"But mine is bigger than hers!"

You squeezed her nipples: "But yours don't produce milk."

Tanya's hunger for success has been triggered: "That's unfair, I haven't had a child. Let wait for my lactation.”

She pulled herself toward you, her mind obviously concentrated on only one thing: getting pregnant and gaining a pair of big, lactated breasts.

You watched her sink down on your big cock and groaned at what was coming.

With a swift move, both of you lost virginity to each other. You soon discovered that her pink pussy was absolutely perfect for putting my cock into.

As she started to move up and down, Tanya said, “Please, please breed me. I need you to fill me up, I need to be swelling with child, now!”

“You’ll get it,” You grunted. “Slutty girl, I’ll give you all the cum that you need to get pregnant.”

These words made Tanya moved faster and faster. She didn't care about anything, as long as she was bred fully and totally by her younger brother's big, thick cock.

Having such an intense mating, it's no surprise that she quickly had an orgasm, but it didn't slow her down even slightest. In fact, it only made her inner muscles wrapped tighter around your shelf like a hungry beast. It made you think that if you didn't give her cunt a creampie, then your cock would be stuck there for eternity.

“Your pussy is so ready,” You said, “You’ve done such a good job, and I’m going to breed you as you wish.”

“Do it!” Tanya shouted as she tried to make you go as deep as possible into her. “I need all your cum. Fill me up, make my tits big and full of milk and my pussy full of hot, white cum!”

“Yes, you slut! Want to be a hucow? Fine, I gonna fuck you as hard as I can to make sure it takes. You’re so fertile, you’re going to get all of this man’s cum.”

You felt your cock swelling up in your sister’s tight pussy and knew that's the sign of your climax. You yelled as your balls contracted and your big, thick cock and started to unleash all of your cum into her.

She moaned, “Yes, yes YES! I love this so much! Please, give me all that cum!”

You kept cumming and cumming inside her until her stomach bulge a little.

“Fuck yes,” You said. “You’re fully bred now.”

Tanya put her hands on her stomach as if she were trying to feel the movement of her pregnancy taking hold on her soft, white belly: “My stomach is so full! I’m being impregnated! I’m going to have milk!”
