Sweet release

The veins, only occasionally appearing, The flesh was perfectly colored to your sister's. The musk, was unlike anything you had smelt before. It smelled like your sister, but not. Like a newborn, but not. Intoxicating, but well... You give it a breath, looking at her she shudders, and smiles a feeling she hasn't experienced.

"So, you want it don't you? Well it's yours."

"On what condition?" She's blackmailing you why would she give you exactly what you want.

"No strings, you want semen produced from this ring. That's what it does. You are 3 shots in at least, if you can resist this for a solid week, then you might get clean. I am giving it to you. Just think if you had instead of acting on your impulses you read the damn thing. I'd be all over you by now. But alas, your stupidity has landed us here. Now, are you gonna give me a new experience or are we just gonna stay here like half naked idiots?" She says having sat up. Staying on her knees she moves a hand to her breast. Giving her nipple a pinch. As a result, a single drop of pre-cum, slides down the shaft in front of you. The shimmer of it, shakes you to the core. Everything in your head tells you, to take a lick. It takes all of your strength to hold back.

"Come on John. Do it." She says squeezing again, another drop. This time it twitches.

That's it. Next thing you know you are on your knees, licking her like a ice cold popsicle on a hot summer day after working a 10 hour shift. Your sister reels back, sure she's gotten oral before, but not like this. Immediately you get more and more pre-cum you know she is getting close. No way a virgin cock could last that long. You didn't your first time. You take her head in your mouth and she bursts down your throat. The bliss of the throbbing head wrapped around your lips, the warmth flowing down your throat, you begin to get hard yourself. The fresh semen, the first ejaculate she has ever produced. And it's yours. You're not sure what is worse, you just sucked your sisters dick. Or you want more?

"Oh my god." She says, laying back, her pussy flooded. Takes deep breaths. "I want more, What about you John?"
