The two of them perk up at the idea of being deflowered, really wanting that, as they go into overtime to work on your enhanced cock. Both of them mildly concerned and curious as to why it is glowing and everything, never seen a doggy cock like this before, but they shrug it off and do their best. Butts up in the air and wiggling and suckling on your delicious cock, with the eldest trying her best to enjoy your engorged cock head, without hurting her mouth on your barbs. All the while the younger sis keeps up with the easy job of licking and suckling on your fat ball sack, eager to see them drained and earn her freedom.
