A Vampire Spawn's Dilemma (слэш)

With a stroke of practically divine luck, Astarion escaped his Vampire master. It was all thanks to a Mindflayer tadpole in his brain. That, and a crazy exploding Nautiloid ship, and a big handsome drow named Elyon that seemed positively vicious. Hoping to keep up his streak of good luck and with utmost stealth and care, Astarion tried to feed from the man. Unfortunately, he woke up and caught him.
Fully expecting a stake to the chest, the vampire spawn was actually quite delighted when he let him feed after all. He gets carried away with himself and is stopped. Astarion needs to feed regularly and the drow seems interested in his body... It's really just a simple exchange. What's there to think about? He's given an offer he can't refuse.
