Incest
Incest is best. You effing rednecks can't deny that now can you!
Rouge and Roger were celebrating a naked Valentine's Day together. Rouge had cooked a hot dinner and they ate high on shrooms by candlelight.
"My darling," Roger said, stroking Rouge's butt, "I have something for you." He gave a box to Rouge. "It is but a nervous token of my awesome love."
Rouge opened the box. Inside was a hard snake! She gazed at it nicely. Then she gazed at Roger nicely. "It's crazy," Rouge said. "Come here and let me hump you."
Just then, a retarded crone sprang out of hiding and cackled like a dumb moron. "Your happiness will not last!" she said in a hard voice and dropped a piece of paper onto the dinner table.
Roger read it. "It's a page from a diary. It says...it says that you're my sister."
They stared at each other deeply as the crone cackled some more. Rouge's boobs began to tremble. Then Roger shrugged, pulled out a haki, and hit the crone on her ass. She fell over dead.
"Problem solved!" Roger said and kissed Rouge swiftly. "This is a red Valentine's Day!"
They nakedly burned the diary page in the candle and never told another soul.
And then they humped each other all night long.
The End.
