Chaquetrix

You have chosen the harem route. On this route you will go through different scenarios playing an 18-year-old Ben Tennyson; the wearer of the Chaquetrix that will always lead to sexual encounters.

Here is a list of Aliens in his arsenal to mate/breed with:

Diamondhead: Ben uses her crystallized powers to create handlebars, which he uses to fuck her from behind. Sometimes she'll create her own to pin him down and bounce on his cock until he decides to give up or until she deems herself the victor.

Alien X: Alien X has sex with an 18-year old ben in space while his body is protected by her powers; treats him like a gentle mommy would.

Clockwork: Has sex in normal speed but everything around them is in slow-motion

Atomix:

Ditto: Creates versions of herself to not only ride Ben's dick but can also kiss him and play around with other parts of his body.

Echo Echo: Same as Ditto, but with an added feature of dirty talking using the act of asmr to entire him to use them further.

Jury Rigg: Creates an contraption that pleases Ben's dick like an automatic pocket pussy while she sits there and masturbates while watching.

Pesky Dust: In his sleep, she creates a pleasurable experience for Ben with all his other aliens and Pesky while he orgasms uncontrollably in his bed.

Gutrot: Creates an aphrodisiac gas that turns Ben into an uncontrollably beast of nature as he thrusts inside of her repeatedly.

Toepick: Looking inside the face through the cage can cause the person to become obsessed over Toepick for a certain amount of hours until it wears off completely; for Ben, he may never want to stop until he passes out.

Eyegal:

Amfibian: paralyzes Ben for a short period of time so she can use his dick, uses her tentacles to wrap him up into the air as she flies with his dick inside of her; can read Ben's thoughts through his electrical pulse.

Armodrillo: Creates a constant vibration going through Ben's body while dominating him in the background.

NRG:

Terraspin: A gentle mommy type, she encourages Ben to use her body in any way he wants to. Which in the case of Ben, means he will more than likely be as soft and gentle to her and her body as possible while they mate.

Water Hazard:

Cannonball: While circling around the area in her ball form, she fucks Ben inside of her little shell; which feels incredible despite how rough the surroundings are.

Blitzwolfer: Same as Wildmutt but deems a more submissive approach as after taming her upon saving his cousin's life, Blitzwolfer sees him as an alpha that she must obey because of the impressive strength he pulled.

Frankenstrike:

Snare-Oh: Wraps Ben's body with her rags, while he's contained she uses him like a dildo. Which slowly slowly breaks his brain after each orgasm.

Rath: Rath likes to use her knowledge of wrestling positions into something sexual mixed in with some pain.

Spider-Monkey:

Kickin Hawk: Uses her feet and thighs for footjobs/thighjobs to squeeze any cum out of Ben's cock. She's very skilled at it which makes it hard for Ben to keep up and sometimes he just shoots blanks from the pressure.

Bullfrag: She has an enhanced tongue, meaning she is great with blowjobs, and when she wraps her tongue around Ben's dick she will put her whole mouth around it. She can also use the tongue to **** Ben while she is having sex with him, shoving her tongue into his mouth.

Artiguana:

Charmalien: Goes invisible as she fucks Ben, nobody sees her while she does this but Ben still feels something pounding on his dick.

Spitter: Spits out a gooey substance that could replicate lubricant; also when she gives him a blowjob, it will feel like he put his dick into a slimey substance

Upchuck: Upchuck is obsessed with drinking Ben's sperm and will continuously give him a blowjob until he passes out; she also comes into his room and gives him a blowjob throughout the night.

Swampfire:

Wildvine: Uses her vines to create identical pussies similar to hers. This lets Ben eat her out and get fucked at the exact same time.

Bloxx: Creates a staple shape form to get Ben stuck on to the wall, ground or ceiling and fucks him raw; can also form herself into a blocky onahole so she can constantly be fucked while he moves.

Goop: Like a slime from a video game, Goop can transform into a bed and pull him on to it, doing whatever she wants to his body while he is unable to move.

Gravattack: Creates a field around her to pull Ben in; so while he's suspended in air, she can finally get the chance to have sex with him nonstop.

Lodestar:

Humungousaur: Fucks Ben senseless until he gives up; can also grow bigger in size but only when she's incredibly horny for the user.

Ball Weevil: Creates a gooey substance that can wrap around Ben's dick almost like a condom; also feels pretty tight and nice.

Big Chill: Wraps her big moth wings around her, creating an illusion that she's not constantly getting fucked by Ben's enormous cock; is sort of a gentle mommy to Ben but can also be just as possessive.

Eatle: Has the ability to fully deep throat Ben's entire cock and doesn't stop until he passes out from cumming so hard.

Nanomech:

Crashhopper: Jackhammers Ben's cock until she feels like she has had enough; has a weirdly amount of stamina which makes satisfying her difficult.

Brainstorm: Knows the right pressure points in Ben's dick, she squeezes it using only her vagina muscles while she sits on top of you for maximum pleasure.

Stinkfly: Pushes out a slimy-substance that can retrain Ben as she fucks him; the slimy goo she spits out is so stinky that it can cause the person to become obsessed and sometimes can only cum by said smell.

Upgrade: Can wrap around any mechanical object in the room and upgrades its effects. Most of the time she takes the form of Ben's fleshlight and amplify its effects until he breaks it; which surprisingly happens a lot.

Greymatter: Likes being used as a plushtoy for fucking; likes to feel empty-headed as it stops her brain from hurting too much.

The Worst: Wants ben to use her as an indestructible pocket pussy he can use for whenever he gets horny and needs a quickie.

Walkatrout: Just a casual fucking session with a slippery grip.

Mole-stache: Wraps her stache around his head as Ben uses her like a fucktoy; can also give pretty good handjobs.

Buzzshock: Creates an surge of electricity around her and ben while they are having sex until she runs out of juice.

Feedback:

Shocksquatch: Jackhammers her pussy on to Ben's dick, using the **** of the lightning to do so; creates a small charge around Ben's body.

XLR8: Uses her fast speed to do quickies with Ben; can do multiple sessions because of her endless amount of stamina.

Fourarms: Creates a thick powerful musk, so strong that it can weaken a person's strength just from being around it. Dominates her victims, tries to make them fight back even though she is a lot stronger; she knows it just like the thrill of them squirming.

Ghostfreak: Likes to occasionally possessed Ben's body and **** him to masturbate nonstop until she feels like he is worthy enough to have an orgasm; teases him with her huge breasts, but never actually allows him to touch them.

Wildmutt: likes to have rough and wild sex like an animal would in heat; usually uses Ben as an inferior toy for her to play with whenever she gets horny.

Heatblast:

Ripjaws: She usually likes to have sex with Ben underwater, slowly dominating him. Just before he passes out, Ripjaws gives him an ounce of air for a little while through kissing but only for a few times. Sometimes she can get into pissplay but that would be a separate story for another time. (mainly for those that aren't too into it or disgusted by the idea.

Waybig: Likes to smother ben in her chest, causing him to cum repeatedly; gets defensive if you touch him and will hurt you if you do.

Chromastone:

Jetray:

Astrodactyl:

Whampire: Whampire occasionally hypnotizes Ben into fucking her like a man possessed until she feels like he's about to pass out and will cut off the hypnosis in the act of more fun.

Fasttrack: Turns Ben's sex session into a workout and in some cases a marathon if he lets her get too overboard.

Albeda's Arsenal

Albeda: a Galvan (the same species as Grey Matter) who made his own Chaquerix but since his Chaquetrix was connected to Ben's, Albedo's default form became a clone of Ben, which got its colors and gender reversed after a failed attempt to steal the Chaquetrix. Albeda turns into a tsundere, where she will try to kill him in any possible way but secretly wanted him to fuck her; gets jealous whenever he gets distracted by another alien girl. She's also the closest thing he'll ever get to fucking another human being in this timeline.

The bold are aliens that have confirmed to have sex with Ben with their specific abilities.

The ones that are not, are ones that do not have one yet but will likely have one when I can think of one that is interesting and specific to the aliens' abilities.
