"Why not?" the succubus replies. "What else would you expect me to do, hmm? I see a lovely, fuckable elf, and an even more lovely angel, all naked, and sweaty, and worked up, and you expect me<em>not</em>to participate? Mmm, imagine if you put out a delicious meal in front of a starving man, and then said 'no, no food for you.' Wouldn't you feel sympathy for the starving man? Of course. And I<em>crave</em>sex, every minute of every day. So, shouldn't you feel sympathy for me?" she asks, all the while driving her tail into the elf's sex, pinning her down and licking and sucking on her breasts.
