New Arrivals at the Buchanan’s Room

    by: DEMONCHICKEN69 Author IconMail Icon
…as Mrs. Mulligan was waiting for one of her latest head swapped and role swapped couples to wake up. She happens to notice two teenagers walking beside each other, heading in the direction of the Buchanan Family’s room. She wasn’t sure who they were as one is a boy and the other is a girl and they seem to be around Scott’s and Margaret’s age. She thought they were just going for a walk or something as she watched the approach the Buchanan Family’s room door.

Thinking they were just going walk past, she sees them stop and the boy pulls out a key card. Which must’ve came from one of the Buchanan Family members and she watches him unlock the door where he and the girl step inside. Which was a bad idea as the room still has the knockout serum still hanging in the air and they walk in, taking a few steps inside before they begin to feel dizzy and tired. Leading to them both passing out within a few steps inside, falling to the floor.

Instead of making Mrs. Mulligan frustrated, she just gets excited that she has two more subjects at her disposal, so she turns her chair to to face her assistant, “would you be so kind to fetch them for me.” Dr. Mulligan tells her.

“Yes Dr. Mulligan.” Her assistant answers and she makes her way up the elevator and back to the Buchanan Family’s room with two beds for the boy and girl.

Where she picks them up off the floor and brings them down to the laboratory and watches Dr. Mulligan get right to experimenting on them. Where her assistant thought she was going to swap their heads with one another like before, but she watched as Dr. Mulligan wheels in two beds that have two headless bodies on them. Specifically two fat hairy middle aged male bodies covered in thick dark hair from shoulders to toes.

Where she watches Dr. Mulligan use her head swapping device and swaps the boy’s head onto one body and the girl’s head onto the other. Making them strikingly similar bodies from the neck down, but Dr. Mulligan isn’t done just yet as she then grabs her role swapping device. Where she changes the boy’s role to girlfriend of the girl and something very specific as in nudist. Then she does something similar to the girl as her role gets changed to boyfriend of the boy and nudist as well.

Once that is done, Dr. Mulligan calls her assistant, “assistant, would you bring these two up the Buchanan Family’s room please.” She asks her.

“Yes doctor.” her assistant answers and brings the latest two out of the laboratory and up to the Buchanan Family’s room. Where Mrs. Mulling observes her assistant having trouble picking up their bigger and heavier bodies. Putting them roughly back where they where earlier before she leaves the room and within a few seconds after leaving. The boy and girl wake up and sit up where they look at each other’s chubby hairy naked middle aged bodies under each other’s necks.

Where Mrs. Mulligan sees them smile and their limp brown uncut cocks to act up, twitching and growing between their hairy thighs until the boy and girl are both erect at a nice decent size. Where they stand up and give their middle aged aching bodies a good stretch before they seem to have a small conversation which Mrs. Mulligan can hear, “what were we doing here again?” The boy asks as he casually plays with his erect cock in front of her.

“Wait, you’re kidding me, you forgot.” The girl teases him.

“Yeah, I did.” He answers her.

“Oh my god, Margaret and Megan our best friends told us to meet them here so we can have sex and stuff.” The girl answer.

“Oh right, how could I forget that.” He says feeling a little embarrassed as they walk to Margaret’s and Megan’s room where unfortunately for them they’re still passed out.

They knock a few times, but get no response, “huh? We must’ve taken too long.” The boy says.

“Maybe, but it’s okay babe, we still have each other.” The girl tells him as she hugs him from behind. Where he feels her erect cock get nestled between his fat hairy ass cheeks.

“True, maybe we can have sex until they do wake up.” The boy tell her.

“We definitely can babe.” The girl tells him as she turns him around and starts kissing him on the lips while they rub their chubby hands on each other’s hairy bodies.

Leading to the girl grabbing his hand and leading him over to the living room couch where she sits down before he steps up onto the couch straddling her with his fat hairy ass facing her as she looks up at it, “mmm…your ass is so sexy babe.” She tells him which makes him reach back with his chubby hands.

Where he slowly rubs and squeezes his fat hairy ass cheeks before ultimately spreading them as much as he can. Giving the girl a clear view of his dark brown hairy sloppy asshole, “you have the best looking asshole I’ve ever seen babe.” She tells him as she reaches up with her chubby hands and spreads his ass cheeks more for him which made him giggle a little before ye adds, “and it tastes just as good as it looks.”

“Oh it definitely does babe.” She says and just like that Mrs. Mulligan watches the boy lower his fat hairy ass right onto the girls face where she immediately began licking his asshole and even sticking her tongue in. While she does that, she strokes his cock at the same time for a short time until he straightens back up. While she sits back and watches him lower his fat hairy ass down onto her cock which slides right in due to his asshole being lubed up and stretched out.

Where he sits completely down on her lap before leaning back the opposite way she did, putting one of his arms on back of the couch before they look at each other. Both flustered and horny as can be as Mrs. Mulligan sees the girl put one hand on his thigh and the other she reaches up and starts playing with his hairy manboobs which he seems to love as he lays his head back with his eyes closed. Where the girl keeps on feeling his hairy body as she feels her throbbing cock deep in his asshole.

Which soon changes as he starts to ride her cock, moving his sloppy asshole up and down her thick shaft while his own gently swings around between his thighs. Where he slowly gets more and more into it as he picks up the pace until his cock is swinging around wildly as they have sex with each other until Margaret and Megan wake up. Where they keep going as Mrs. Mulligan has her breasts out and is fingering her vagina as she watches her latest subjects having sex with each other.

Which is her favorite thing to see after she’s experimented on her guests, but this type of sex is her most favorite as she continues pleasuring herself while watching them. Watching him ride the girls cock like a professional for a few more minutes until…..
