You thrash more wildly, your mind racing - the situation seems to grow more dire by the second!

As you are distracted trying to free yourself from her grasp, a second batgirl swoops down on you from the front and hugs you tight with her wings! The moment she lands on you she plunges her lips against yours - and you feel a second pair of sharp stings pierce through your lips. Both bat girls moan happily as they start draining you with their lips and squeezing you with their wings.

The bites begin throbbing with a deep tension that makes your muscles quiver, and grows only more intense as they keep sucking out your blood. Your body is gradually growing cold, but also tingling with pleasure as their bodies gyrate against yours. The colder your skin becomes, the warmer and more arousing it feels to press against them. Delighted moans echo through your ears as your mind swims - it's becoming harder and harder to focus on trying to escape!

As you try to pull one hand free to push the newcomer away, you realize your muscles are too stiff to even let go of the rope. In fact, all of your body has become ice cold - save for a swelling heat that persists between your legs. The bat girl at your front is all too eager to grind against your bulge, working you to erection even faster! The intense arousal makes your heart beat faster, only aiding the batgirls in more rapidly draining your blood.

You moan and grunt lustfully into the **** kiss, your lips and neck flushing as the last of your blood collects there, eagerly suckled and kissed out of you by the batgirls. Your brain starts to shut down from blood loss, but at the same time you can feel your body become animated by a chill of life, inhuman yet orgasmic. As the pair thrust and gyrate against you, you feel your body finally go numb and your eyes slide shut...
