Cum her out

Sitting down on your sister’s bed, you ponder your next move. You could do nothing, and wait as your sister slowly churns down into cum.

Pros – would feel fucking amazing; wouldn’t have to worry about her telling anyone; she wanted it

Cons – would have to lie to your mother, or eat her too; you were having fun before she fed herself to you

After thinking for a while, you decide to attempt to cum her out.

Stroking your massive shaft with both hands, it doesn’t take long to orgasm, and with a great welling feeling in your balls, they empty themselves all over the floor. At first is a deluge of creamy hot cum, but then, with great pleasure and a loud wet slurp, comes the now naked and extremely slimy form of your older sister, who promptly gets hosed down with the rest of the food-turned-cum left in your sack.

She kneels on the floor for a minute, coughing and spluttering. Then she looks at you with equal parts annoyance and awe.

“Okay bro, that felt fucking amazing, but why did you let me out? I wanted to melt in there, my last orgasm would’ve been mind-blowing!”

“I’m sorry Connie, but it would’ve been a tough one to explain to mom. And besides, I don’t want to kill anyone, especially my sister!”

“Ugh fine, I guess you have a point. But now you have to make it up to me.”

“You’re a real degenerate, you know that? But fine, what do you want?” you say with a half smirk.

“Alright, if you want me to stay quiet about what you can do, you have to use that cock of yours to eat anything I say – and I mean anything.”

“I- I can work with that” You say with a grin. At this point, what's the worst that could happen?
