Lily Starfire, unaware of her stepbrother Ace Bigs' presence, was putting on makeup while still nude. As she applied lipstick, she noticed that the door to her room was slightly ajar. Upon discovering him peeking in, she confronts him about his actions. Ace admits to staring at her because he couldn't resist her beautiful, massive boobs. He explains that it's not his fault; her body is just too perfect.
Lily reassures him that there's no need for sneaking around like this. As stepsiblings, they can explore their mutual attraction in a more open manner. She suggests that if he wants to touch or admire her tits, all he has to do is ask. Intrigued by the idea of being upfront about their desires, Ace decides to take things one step further.
He grabs some oil and begins an intimate massage of Lily's stunning, supple breasts. As they both continue to explore each other's bodies, their passion grows stronger. Soon enough, they find themselves engaging in a raunchy, wild sex session that includes various positions and movements.
Lily takes control at one point, straddling Ace and riding him with her enormous booty shorts accentuating the incredible curves of her bubble butt. Throughout the encounter, both parties make use of their unique body features - such as Lily's piercing and tattoo - to heighten their pleasure.
In a final act of passion, Ace penetrates Lily from behind while she leans against a wall for added support. As he approaches his climax, he pulls out at the last moment, directing his cum onto her pretty face and mouth - leaving her covered in his satisfying release.
