Scene 1:
After months of sneaking around with your stepsister, the two of you are faced with a surprise pregnancy. Despite the initial shock, her pregnancy hormones have made her ravenous for your cock, and it doesn’t take you long to adapt to her frisky new personality. When your stepmom heads out for the evening, your stepsister’s upon you in moments, begging you to take her in multiple positions until the two of make a sticky mess all over the living room rug. Not yet satiated, she urges you to sneak into her mother’s bedroom with her and rummage around through Mommy’s impressively large toy collection.

Scene 2:
Your stepsister boldly tears apart the contents of your parents’ dresser and discovers an array of brightly colored toys. She lies back in her mother’s chair and begins to slide them inside herself as you look on, mildly horrified by her brazenness but more in awe of her than ever. After explosive orgasms from you both, she dips her hand back inside Mommy’s dresser and makes a puzzling discovery. A photo of…her grandparents? As she begins to tell stories about her late relatives, you interject to point out that the photo depicts YOUR grandparents, not hers. She laughs and assures you that you’re mistaken, but striking similarities lead to the sobering realization that somehow, your parents came from the same family.

Scene 3:
When her mother arrives home, your stepsister corners her and demands to know how she’s related to your father. She sighs, and confesses that she’s your dad’s sister and that your stepsister is not only your first cousin, but your TWIN. She goes on to detail the circumstances of your birth, and ends by expressing her relief that the two of you aren’t as warped as she is. Your panicked sister exposes your relationship and blames your mother for her pregnancy, sputtering a slew of obscenities before storming out of the room.

Scene 4:
Mommy gently approaches you, apologizing for her years of neglect and promising to make it up to you. She slowly gets down onto her knees and takes your cock into her mouth, urging you to let her suck your troubles away. You’re lost for words, but her warm lips feel so good that you can’t help but explode down her throat. She bends over and instructs you to impregnate her too, adding that your father would be fully on board. She’s too alluring to refuse, and you give her what she wants without any hesitation.
After you’ve finished inside Mommy, your sister sheepishly enters the room and admits to having watched the entire thing. She apologizes for her initial reaction, and gushes about her newfound love of familial intimacy. When Mommy leaves the room, she shamelessly kneels down and delights in tasting her mother on your cock. She bends over for you and you slide inside her once more, passionately thrusting pregnant little body against the wall until your father walks in. Sounds like the three of you have a lot of explaining to do.

You have no memories of your mother. Mommy left you with your big sister when you were young and all you’ve ever known is Sis. The two of you have developed a unique bond as she’s grown into the role of your caretaker and more recently, your lover.

Your sister is worried about Mommy. Although it’s hard to keep track of her dating life, your sister suspects she’s been dumped by one of her much younger boyfriends and the rejection has hit her hard. Sis knows Mommy thrives on the validation she receives from young men and thinks you ought to help boost her spirits by paying her a compliment. You don’t particularly enjoy dealing with Mommy during her depressive episodes, but Sis makes you an offer you can’t refuse (a blowjob) and sends you off to Mommy’s room with a kiss.

Mommy is touched when she finds out you’ve created her Sim lookalike, and oddly unperturbed when she digs deeper to find her doppelgänger is in an illicit relationship with a virtual stand-in for you. She playfully shrugs off her findings, but when you bump into her in the hall on your way to bed, it’s clear she hasn’t been able to shake her discovery. She doesn’t quite seem her usual self as she leans in and probes you to share your darkest desires. With a sultry glance and a flourish of her silk robe, she lures you into her bedroom and you look on in disbelief as she unveils a risqué ensemble, not unlike what you’d dressed her character in.

Goddamn it, Son. You’ve gotten ANOTHER small object stuck inside yourself and Mommy has to come to the rescue yet again to help remove it. Mommy is starting to suspect you’re purposefully hiding things in your asshole because you secretly love the way her gloved fingers feel sliding inside you and stretching you open.
