It was actually your sisters... being carried!

To your shock and terror, it was your sisters being carried by a rival flock of screeching harpies. Their feathers were snow white and their exposed human skin was a rich dark brown which contrasted with the fair color of you and your sisters. They were heading towards the family nest, no doubt marauders coming to humiliate the flock in their own home and take it after turning them into cum buckets for their thick, ebony poles. The prospect alone made you cock drip and your nipples stiffen. A part of you relished the idea of those black rods massaging your guts but the rest of you craved to massage theirs.

Focus, damn you!

There were twelve of them and only five of your sisters. Almost half of the marauders held them up by their wings while the other seven bullied them by pecking at your sisters soft spots and slapping their cocks against their faces, breasts, and asses, taunting them like little meals you and the lock snagged. Your sisters thrashed but put up little resistance against their kidnappers. Your sisters were probably ambushed and since they were outnumbered too, you doubted they could've done much to hold the rival flock off before they were beaten into near submission.

Luckily for you, your vision was better than the average harpy and the darkness of the cave kept you from the invaders line of sight. You had enough time to briefly think, time to swiftly act before they arrived.

Stupid, sexy vultures. You had some time so what would be a good call...
