I had an idea for a story where a guy's girlfriend bears an almost identical appearance to his biological sister, and has very repressed sexual desires toward her. His sister, however, is very aware of these repressed desires and shares them--but she is committed to expressing them. As it just so happens, not only is she and her brother's girlfriend good friends, but the girlfriend is also something of an unrealized cuckquean with a sibling incest fetish kink of her own.
I imagine that the girlfriend has expressed her cuckquean and sibling incest fetish to her man, who flatly refuses to have sex with anyone else because of his commitment to her, but reluctantly agrees to indulge in her sibling incest fetish with some light roleplay. They get into it referring to each other as "my sister" and "my brother"; all the regular stuff from "fuck your sister's pussy" to "I love my brother's big cock." He's reluctant to get into vocalizing the roleplay, but soon ventures into it with timid questioning, "You like your brother's thick cock?" until he's into it with statements "I love my sister's tight, wet, pussy." His girlfriend is overjoyed, the lust keeps ramping up and just as they're both past the point of no return, she screams out to cum inside his sister, (sister's name), and he does, groaning her name.
In the aftermath, she senses his guilt, and not wanting to shut off further romps into incest roleplaying, immediately apologizes for mentioning is actual sister, advising that she lost control over herself in their shared passion and the very first time she'd ever been permitted to explore that side of her sexuality. To foreclose on any insistence by her boyfriend not to mention his sister again, she just pivots into talking about how hot it was, how hot he was, and how grateful she was for it.
Little do they know, her boyfriend's actual sister came home and not only overheard them, but ended up discreetly watching them have sex, masturbating to her own climax when she heard and saw her brother pump her friend full of cum while groaning her name. She ends up reaching out to his girlfriend and they stumble into a conversation where the sister admits that she saw and heard their incest roleplay, the girlfriend needles her into admitting it turned her on and the sister vocalizes her own incestuous desire toward her brother, the girlfriend and sister openly acknowledging that due to their identical bodies and look that the brother/boyfriend most likely shares that desire, and the girlfriend's revelation that while she loved the roleplay, nothing would be hotter than indulging in her two biggest fantasies: being a cuckquean by watching her boyfriend engage in incestuous sex with his own sister.
The two make plans to ensure this happens as soon as possible. The girlfriend takes her boyfriend out for a night on the town, but uses that opportunity to slip him a large dose of crushed viagara to ensure he'll perform no matter what, and also convinces him to consume an adequate quantity of psilocybin mushrooms to get him to open up and experience more joy on their night out--but secretly, to make him more accepting of his already latent incestuous desires toward his sister. They get riled up and get home to her place, and asks if they could engage in a little brother-sister roleplay again since the last time was so hot. Being open because of the mushrooms he agrees, and she asks if she could indulge in a fantasy where she ties him up and blindfolds him. He excitedly agrees--most likely because with him immobilized and not capable of seeing, he can feel more comfortable being more of a passive actor in the roleplay.
The girlfriend slips a blindfold on him and ties his wrists and ankles to the corresponding bedposts, and then his sister takes over while his girlfriend narrates what she's doing to "herself" (when in reality, she's essentially telling his sister what she wants to do, describing what she thinks she must be feeling, etc) and slips into the incest role again. This time, however, she has no qualms "pretending" to be her boyfriend's actual sister. Although he initially seems to struggle against roleplaying that way, his girlfriend is cuts him off by insisting that this is what he wants-- that his "girlfriend" is identical to "her" (his sister), and how she heard him roleplaying with his "girlfriend" (her) and how he groaned her name when he came inside her. He relents and gets into it fully, calling his "girlfriend" by his sister's name as his sister manipulates his body. His girlfriend stays near his sister to narrate, and eventually he catches on (based upon the breathing and movement and sounds), that there are two women in the room--at which point, his sister pulls the blindfold to reveal she's riding him and his girlfriend is masturbating watching them. While he struggles a little at the revelation, his sister is insistent that this is what he wanted, confronting him with his vocalizations both then and when he first roleplayed with his girlfriend. He tries to appeal to his girlfriend (weakly, because he knows she's right) but she insists this is what SHE wants and wants to see. The women begin egging one another on, with the sister asking her if this is what she wanted to see, and the girlfriend confirming that it's the hottest experience to share her boyfriend for the purposes of seeing him commit the ultimate taboo. The turn their attentions to the brother/boyfriend, pestering him with questions and insistences until they know they have him committed absolutely to the deed, releasing him from his bounds to have him begin ravaging his own sister, plowing her until he cums inside her, then witnessing his girlfriend eat their creampie, only to roughly take her from behind, watching his sister's face orgasm while he unloads into his girlfriend's pussy, who is cumming at the same time.
They continue on until they fall asleep, with his girlfriend informing him that she is forever ok with her boyfriend fucking his sister and the sister fucking her boyfriend whenever either of them want, so long as she gets to hear all about it. Upon waking the next morning, the boyfriend brother finds himself in bed with just his sister. He gets into the shower to think about things, and she soon joins him and while he is reluctant again, she wins him over and they fuck loudly in the shower. After they get out and make their way to the kitchen, they find the girlfriend, happily waiting for them with coffee and pastries that she went out to grab (which is why she wasn't in bed with them that morning). The story ends with them sharing with his girlfriend their shower encounter.
