Part 3 provides a flashback showing how Siren learned all her naughty ways from her mom Caroline (Syren de Mer), starting with a dinner featuring Siren's dad Andrew (Clarke Kent) and guests the Andersons (Juan Loco and Laney Grey). Siren tells us about her mom's expertise at deception, and we see Caroline playing footsie with interior decorator Mr. Anderson under the table with her husband right at the very same table! Siren was eavesdropping outside the bedroom door when her mom made love to Mr. Anderson. Watch the steamy scene, ahead of more promised action "to be continued...".
Ashley's jealous of Sarah's crush on Ashley's stepdad Joseph (Ryan Driller), but Joseph is affectionate with her too, calling his daughter "Kiddo". A friend of his, Ralph (Derrick Pierce) is coming over to fix their car, and Ashley's in charge while daddy's away.
Eyeing Ralph working under the car hood, Ashley thinks to herself: "Why couldn't he be the one?". Yes, she's anxious to be freed from her virgin status, finding it awkward for an 18-year-old about to go off to college. She enjoys chatting with this friend of daddy, who's known Joseph forever.
Whiling away the time together, they innocently kiss, and Ashley sheepishly confesses: "I'm still a virgin". Ralph laughs and says: "I didn't think women like you still existed". Watch the seduction as this older man/younger woman scene unfolds...
Later, that evening they're on the sofa watching a movie on TV, with a big bowl of popcorn to share. Juan snuggles a bit with mommy to warm her up in the cold living room, and even gives her an appreciated foot massage. As the 18-year-old's wandering hands move up mom's thighs, the busty MILF shows signs of becoming aroused, but is intent on resisting her horny 19-year old kid's obvious intentions.
Juan's eyes grow wide as he spies a large wet spot on her pink panties, but before they can kiss, they're interrupted by her phone ringing -it's daddy on the horn. With Juan lightly kissing her knee she says "That's a good boy", while chatting with her husband. She hides her passion from daddy as Juan eats her pussy.
When the phone is passed to him, Juan clearly enjoys deceiving his dad, and as she murmurs: "You really know how to take care of mommy", Juan penetrates her pussy with his big dick. Watch the taboo scene unfold...
Instead Liz and her friend Lisa are going to a night club with fake IDs, neither sibling afraid of getting into trouble once their parents return. Ricky flatters her and eventually convinces Liz to change her plans and make his party a success. He hugs her in gratitude, and she makes it clear it's on one condition. "I don't know what it is, but you owe me one", she tells him, and they make a pinkie promise to seal the deal.
Later, the sound of the guys whooping it up at the party are heard, as Liz goes to her bedroom carrying a drink. Ricky visits her and finds that she's upset. She confides in him, that she's still a virgin. "I'm just not as good with the guys as you are with the ladies", she admits. She makes fun of all the girls she's seen coming in and out of his room, and suddenly mounts on top of Ricky, making fake moans.
Ricky shushes her, declaring: "They're going to get the wrong impression!", as he hears loud knocking on the locked bedroom door. "Exactly. I want them to think I'm losing my virginity", she explains. "They think that you're Mark (her would-be boyfriend from the party). "No, this is a bad idea, sis", he maintains, but she insists: "You owe me, remember?". Liz starts dry humping on top of him, moaning loudly, and Ricky laughs at her attempts to mimic what she's heard in dirty movies.
"Well, if you're so experienced, why don't you just show me yourself?", she demands. He reverses their positions, throwing her on her back on the bed, and pretends to hump her, still both fully clothed. The physical contact starts turning both of them on for real, but Ricky doesn't feel right, even pretending -after all, she's his stepsister. Threatening to tell their parents about his throwing the party, she insists they continue, and that he remove his pants. "You're zipper's rubbing on me and it's uncomfortable", she explains.
Reluctantly he obliges, revealing a huge boner in his underpants. "Oh wow, that's so big", Liz remarks. He's embarrassed, but she demands: "Just get on top of me again". Their fake sounds of passion turn real as he simulates sex with her, and she suggests: "Do you want to see my tits?". Things accelerate when she shows him, and he naturally covers her nipples with his lips. They continue "pretending" but soon pass the point of no return. Watch the taboo scene unfold...
Siren apologizes to Mark for messing up the scheduling of an open house, and the real estate agents are back at the mansion to try again. There's a mutual attraction, but both profess a reluctance to betray Mark's wife Lisa. When Lisa calls during their conversation, Siren takes the cell phone from Mark and hangs up, then kisses her co-worker, mighty tempting for him to resist. When Lisa phones again, Siren answers: "Hi Lisa. Yeah, he's somewhere around here -he left his phone on the counter. What's on your mind?", she asks, while shoving a bewildered Mark down abruptly on the leather couch.
She listens to Lisa, while undoing his pants. "You did everything I said? And how about all the little tips and tricks? And how about the oral trick I taught you?", she asks, while starting to gently give Mark a blow job. She delights in fooling the best friend she claims to be loyal to. "Can I make a guy cum in ten seconds from that trick?", she murmurs, all the while servicing Mark's cock. "I can", she asserts, but you don't want to do that, not before the guy cums first", Siren tells her. Watch the naughty scene unfold, leading to the shock conclusion to the story.
