Thrust/Wake up alone
From Torg Adventure
You wake a couple times in the night and kiss Tracy's head. Then one more awakening, and you find your bed empty. She must have sneaked back to her bed so you wouldn't get discovered by Dad and Mom.
Over the next three weeks, you and Tracy find many times to play with each other, in the store room and in the shower even, and every night she creeps into your bed for at least an hour of wild, muffled sex. In all that time, you've never talked about the fact that you are fucking with no protection. You've filled her womb with countless loads of wriggling sperm.
One night after fucking in your bed in the three most common positions for you two -- missionary, cowgirl, and doggie-style, Tracy clears her throat.
"{firstname}, I'm pregnant. I barfed my guts out the last two mornings and my tits are very tender. I don't care, because you have made me so happy these last weeks. Besides, someone has to have babies, and it might as well be me," she whispers to you.
You are not surprised, but you whisper to her, "Oh, my God! That's wonderful, Tracy! You'll make a great mother." You give her a deep tongue kiss and she kisses you back passionately. You've gotten your sister knocked up and she's happy about it!
"I think you'll make a great daddy too. It's wonderful for us, but Mom and Dad are going to figure it out when I start showing, and then they will go ballistic," she says after the lovely kiss.
"Well, they can't put the toothpaste back in the tube, so they'll have to accept it eventually. We can tell them just before you start showing. The further along the better." You rub her belly, thinking about the life growing in there. A porn movie of your sister, big as a house and on her knees fucking you, runs through your head for half a minute.
Tracy kisses you again, gripping your cock to stroke it back to hardness. She breaks the kiss, but keeps rubbing your cock. "Promise me, no matter what happens, that you'll keep fucking me, even when I'm a fat pregnant whore. Our time together and this baby are the best things now."
"I promise." You kiss her again and roll on top of her. She spreads her knees apart and you slide right in. In just a few minutes, you both grunt out your climaxes as you fill her with sperm that has no place to go.
As you lay in each others arms, Tracy whispers, "Now I feel your heat inside me all the time. I love you."
"I love you, too, Tracy. I want you to be happy, and I can't wait to see our baby."
"Well, we'll just have to wait nine months. I hope its a boy and he has your eyes," she says.
You reply, "I hope it's a girl and she has your tits." You both giggle.
Then you fall asleep.
What next?
