In honor of Shark Month, Penelope Kay and her buddy Ginger Gray are enjoying themselves while playing with sharks. Rico Hernandez, Penelope's stepbrother, enters and inquires as to what they are doing. Rico declares that he will be the dominating shark when the girls give an explanation. He continues by saying that Penelope might bleed during Shark Week so he could play the shark. As Ginger watches, Penelope accepts the dare and declares that she would bite Rico very hard. Rico suggests he could enjoy it, to which Penelope gives him the boot from her room. After Rico leaves, Ginger suggests that perhaps the reason she and Rico quarrel is because Penelope wants to have sex with him. Rico wants to fuck and breed with her, Penelope snaps back, and she knows this because she overheard him talking to a buddy on the phone. Later that day, the girls are lying in bed together, masturbating, and becoming distracted with their shark toys. Rico walks in on them once more, only to receive a severe glare. Luckily for him, he remains invisible to them. Until Ginger catches him, he can just stand there and lust after his gorgeous stepsis and her buddy. She gives him a do-me smile while keeping her distance from him and stepping up her shark dildo game. Ginger doesn't stop flirting with her toy till Rico finally walks away. Later, Penelope confronts Rico after dressing in a shark hoodie. The evident sexual tension between the stepsiblings is exploited by Ginger, who then lets Penelope unleash her inner shark and attacks Rico. After a minute of observing the two wrestle in bed, Ginger joins them to extract Rico's erect dick. Penelope makes feeble complaints, but she gets Rico over it by going in for a double BJ. Then, while Rico fucks her from Rico drops to the ground to let his sultry stepsis to ride him in reverse cowgirl before exchanging places with Ginger, who then gallops out in cowgirl. Ginger perches on Penelope's tongue and gives Rico the want to cum inside his stepsis as soon as she takes him between her thighs. Following orders, he gives Penelope a cream pie filled of tiny swimmers for Ginger to remove and snowball with her best friend.
