Agreed with Jenna, the size is just a little too exaggerated to take seriously for me. Like, the length is more or less alright, but the girth is just plain silly looking. Half of that girth or a little less would be perfect imo for this story's purpose.
would love to see continuation of this, wether it be brother being the warm up cock and fluffer to the girls, girls riding his face and cock before and after riding his sister and/or brother being pulled deeper down the hole and he eventually becomes a cock sleeve to all his sisters/mothers futa friends
