Let her drink your seed
From Torg Adventure
You decide it would be best to not ruin a good thing, and let Doe continue her work on your raging hard on. She nimbly worked her mouth along the whole length, tonguing up and down and particularly at the sensitive underside - causing you to lift your hips up and off her bed as she does it.
"Oh god Doe, that feels… OOoooo…" you manage to get out, the last bit not even able to form a coherent word.
"If you think that felt amazing John, wait until you feel this!" she punctuates with a grin, before taking the entire head of your bloated cock into her mouth. She continues to do that for a few moments before beginning to take even more of your cock in her mouth - your innocent little sister doesn't seem so innocent, give the deep throating she's giving you right now!
So it's no real surprise when just mere moments later you're cumming - and far too soon. Doe is ready though, and eagerly swallows the thick seed you are [sadly, uselessly] blasting down the back of her throat. As your softening cock slips from between her lips, you glance downward. "Sis… that was… amazing."
"I'm glad you liked it John - that was your reward for giving me the time of my life last night!" she replies, slowly crawling up your body, her cunt leaking a trail of last night's efforts along your thigh as she does so.
"Oh Doe, you didn't have to do that because of last night - I'm pretty sure I enjoyed that as much if not more then you did!" you say with all honesty - especially if you find you knocked her up!
"Well, I hope we can go again later today" your sister says. "But for now, we really should get ready - I'm sure mom and dad are up by now… I would hate to think what would happen if they caught the two of us like this!"
And so, you slowly gather your clothes and head out of Doe's room and back towards your own. However, your bladder is beginning to need some attention - stop in at the bathroom or head back to your room and throw some clothes on first?
Time for a quick pee?
