Della Cate and Sky Pierce are enjoying face sitting so much

Della Cate and her friend Sky Pierce are hanging out together. Della can tell something is off with Sky, and Sky reveals that she just learned she was adopted. As the girls try some clothes on, Della comments that she has a new stepbrother and that they can both do stepsibling stuff with him. When Alex Charger wanders into the room, he agrees that it's a terrible thing to learn you might be adopted.As soon as Alex agrees to treat Sky like his stepsister, Sky begins asking if her outfit looks okay and if her nipples are pointy enough. Just as Dellas gets in on it, Alex's mom comes home and interrupts them. The girls wait until they're alone again and then corner Alex to show him that they're not wearing panties beneath their miniskirts. Rubbing Alex's dick is the prelude to them working together to suck it, then climbing with Sky on top of Della to create a double pussy stack for Alex to eat.The girls switch their positions so that Della is sandwiched on her knees between Sky's pussy and Alex's dick as he gives it to her in doggy. Then it's Sky's turn in the middle with Della on her face and Alex between her thighs. When Alex gets on his back, his stepsis rides his pussy while Sky plants her twat on his tongue. Sky scoots forward for a reverse cowgirl ride, bringing Alex to a cum shot that leaves the girls a nice load to play with.
