I have lots of ideas and plot lines but most wouldnt fit for the swap series persay, but would love to see in other TS sites. This may be a long one so buckle up lol One I think would be hot is...

Well you have a single mom and her two kids (son and daughter). She gets a visit from her sister and her sisters daughter. Then son hasnt seen his cousin in a while and cant help but be a bit attracted to her. She thinks her cousin is cute too. After a few days of their visit, cousins catch up and get really playful, maybe even a bit flirty?? They stop short of doing anything too frisky but they catch glimpses of each other naked. Either mistakenly seeing her in the shower. He cant help but stop and stare. Later she catches him masturbating. She too cant help but stop and stare. He noticed her watching but doesnt say anything. He later brings it up "I saw you watching me." She tries to deny it but he knows the truth. "You like what you saw cuz?" She tried to play it off like it was a mistake but he knows better. He inches closer to her. He confesses his attraction to her. "I know you're my cousin but I cant help it, you're fucking hot!" She blushes but slyly admits shes kinda attracted to him as well. We know where this goes.....*SEX SCENE*! You can fill in the blanks. ;-)

During the climax, his aunt walks in and catches them! She is both shocked and appalled! "WTF is going on here?! Thats your cousin!" She storms out of the room. The son (lets call him Brad), tries to smooth things over with his aunt. "Please dont tell my mom, we got carried away, it wont happen again!" Still in a state of shock, "How could you do...that, with your own cousin??" After much begging, she agrees not to tell anyone.

Another day goes by and the aunt is going to take a shower. She didnt notice Brad already in the shower. She goes to leave but catches a peek of his cock. Its huge and hard. She is frozen in awe. "OMG, that thing is huge" she thinks to herself. Part of her doesnt blame her daughter now, but she tries to shake it off "What im I thinking, thats my nephew!" She goes to her room and cant get the image of his young hard cock out of her head. She keeps telling herself its wrong to think of her own nephew but she cant help it. She starts to touch herself. Here we get a nice masturbation scene were she fingers herself to climax. Unbeknownst to her, Brad had also caught her spying on him in the shower and had followed her to her room. He watched the whole thing, watched her finger her pussy thinking of him.

Next day, his cousin still in a euphoric state from their taboo tango, that she had to tell someone, and that someone was her other cousin, his sister. She struggled with revealing what they did and her cousin could tell something was up. "What happened, tell me." "Ok, but you have to promise not to get mad and keep it a secret!" "Yeah I promise!" She slowly reveals that she fucked....Brad! "What?? Brad? My brother Brad?? Your cousin? Are you serious?" "I know I know, but it was so damn hot and his cock..." She stops her and just sits in silent disbelief. After struggling with what to say, she found herself becoming curious. "You had sex with Brad?" Her cousin nods. And she shocked her by saying "well, how was it?" She then started going into every elicit detail. And Brads sister started going from shocked, to intrigued and then, despite herself, was she getting turned on? Hearing her talk about her brother was doing something to her. Her cousin could tell. "Are you getting turned on?" "No!" she says which they both knew was a lie. This goes to both of them getting turned on and they start fondling each other. Kissing, touching, and soon clothes come off...*SEX SCENE* lol

During their taboo lesbian affair, guess who comes in, Brad of course. He watches them going at it for a bit. Watching his cousin eating out his sister. He walks in "Well well well, whats going on here?" His sister jumps up embarrassed, but Brad doesnt care. "Well I guess the cats out of the bag, can I join?" His sister has as shocked look on her face, but he doesnt wait for an answer and goes down on his cousin, her ass already in the air, and she continues to lap at her pussy. Brad eventually takes over for his cousin and goes down on his sister. *SEX SCENE* fill in the blanks lol sis/bro/cousin threesome!

Later.....the aunt overhears her daughter and her niece talking about what they did with Brad. "What?? Again? And with his own sister too??" She decides to confront Brad later about this, this has to stop. Later after dinner she talks to Brad alone in his room. "You cant keep doing this, I might have to tell your mother." What are you talking about?" ask Brad. "Dont play dumb with me, I heard what you did with not only your cousin AGAIN, but your own sister too???" Brad doesnt know what to say....or does he. He didnt forget what her saw the other night. He brings up that he caught her spying on him in the shower, and he enjoyed the show after in her bed! Her face turns beet red! "Its ok, you couldnt help it, neither could we, we all got caught up in the moment. I mean, you're all so hot!" She smiles but says, "Thanks, but we are family, its wrong!" "I know, but we arent hurting anyone, and I have to admit, thats makes it even hotter." She can see him staring at her breasts, she glances at his cock in his pants, theres a huge bulge. She can feel herself giving into temptation. But with her own nephew?? "Fuck it!" *SEX SCENE* lol

During their hot taboo fuck, I guess they made too much noise. The one person they didnt want to know comes upstairs. She opens the door and finds her son and sister naked in bed. "OMG, what are you two doing?" She takes out most of her rage on her sister, "Thats my son, your nephew what are you thinking?" Aunt follows her out of the room and trying to clear her name and not thinking she spills the beans, "Im sorry sis, but after I caught him with my daughter and his sister I got carried away!" "WHAAAAT?? You caught him with who?"

Later...mom has a talk with the whole family, about what they done. About how its wrong and how they better never do anything like that again. She will try to work through this.

Everyone is in their separate rooms. They agree not to fool around with each other, but they are all still horny. Mom is walking the halls and hears moans coming from every room. Fearing the worst she peeks in her sisters room. She is alone in her bed fingering her pussy. She sees this and tries to look away, but cant . She watches her sister fingers slipping in and out her wet cunt and cant help but get a shiver between her loins. She even hears her sister quietly say "Oh Brad" which shocks her. She slowly closes the door and composes herself. She continues down the hall, and heard more moaning, its her daughters room, she peeks in and her daughter and niece are 69ing in her bed. Again she cant believe her eyes, her own daughters ass in the air, face buried between her cousins legs. This time she starts to touch herself. Watching them go at it, she finger fucks herself feverishly in the doorway. She almost climaxes when she feels a hand on her thigh...its Brad. "Oh no, sweetie!" and she runs to her room. Brad follows.

"Go away Brad, you shouldnt have seen that! And I shouldnt have done that, it was wrong." "Its ok mom, dont be embarrassed." He tries to console her and sits on the bed. Shes wearing nothing but a nighty. "You got caught up in the moment, its ok." No its not, she says, we shouldnt be doing this, what was I thinking!" Brad thinks for a second and says "Same thing I was, its was hot, wasnt it?" She just stares at him. "I mean, the fact thats its so wrong makes it even hotter, doesnt it?" She then says, "That doesnt bother you? I mean, being with a family member?" Brad thinks for a second and says "Actually, no. The fact that we're related turned me on even more. God I hope that doesnt make me a sicko!" "You arent a sicko!" she says. "You are my son, and I love you." They hug and he feels the weight of his mothers breast pressed against him. They stare at each other and he goes in for a kiss. They kiss for a bit, and Brad looks at his mom, sitting on the bed, and says "Oh mom" and buries his face in his mothers tits. He pulls them out and starts to suck on them. "OMG, but this is so wrong, what if someone finds out?" "They wont". Annnnnnnnnd *SEX SCENE* lol Mom and son go at it, going down on her, to BJ, to various positions of course.

Toward the end of the sexcapade, as Brad cums all over his mothers ass and back, his sister, aunt and cousin enter the room. Guess they weren't as quiet as they thought. "Well I be damned, so much for acting like a family huh?" Mom, embarrassed, simply says "Well I guess a family that plays together, stays together!"

Next Morning....they are all at the breakfast table. The doorbell rings. "Who can that be?" Mom answers the door, "Hey sis, surprise!" Its her brother and his two sons! She looks back at the dining table and they all share the same grin. This is gonna be an interesting weekend! ;-)

THE END
