I promise them that they can live - if they each take a hit of a drug I've been developing. I need more test subjects, after all. Assuming they say yes (and they will), I'll pull each one in and inject them with the syringe full of the material, then sit back to watch them react. It's an aphrodisiac, of course - within twenty seconds, they'll be pawing at themselves, moaning, and within a minute they'll be begging to be fucked. I'll remain impassive, though - so they'll have to turn to each other. The fucking will start off awkward as they try to ignore whatever feelings they have for each other and whatever relationship they have already, but that won't last long. By the end of a few minutes, they'll both be moaning and whimpering and screaming for the other to fuck them harder...

Of course, that won't last long. Maybe twenty minutes, maybe thirty. When the first one finally orgasms, she'll realize that something is wrong - the orgasm won't end. It just crashes on, and on, from pleasurable to gut-wrenching to agonizing - and the other one, oblivious, will bring herself off seconds later, to the same reaction... their bodies will writhe, twisting and spasming uncontrollably as the orgasm refuses to subside. The squirting will turn to dry spasming, and then a release of their bladders, and then - then the fun part. With nothing else to expel, the girls will start to cum blood, as vessels inside their vaginal walls rupture and tear open. At first, this will be merely painful and terrifying - but an hour in, the tearing will grow worse, and worse, until the uncontrollable and savage muscle spasms will literally start to tear their bodies apart.

By the two hour mark, I assume both will be dead - if not from bleeding out, then from heart failure. Or shock.

The legendarily leggy Raven of the Teen Titans kneels before you, unable to move in her bindings, exhausted from the extended duel. FINISH HER!
