(It was 10:23 pm evening at the Test residence and the Test family had finished their dinner, which is meatloaf made by Hugh Test, much to the rest of the family's dismay, but they'd ate it anyway. Now, it was finally time for the Test sisters to lead Kevin to their lab and began their experiment. They had typed away on their huge computer before walking back to Kevin with a glass container with pink liquid in it.)

Kevin: "So, is this safe?"

Mary: "Totally safe, dear brother. All you need to do is drink it and step into that machine over there." [points at the machine]

Susan: "It will make a new every field around you that will make opposite gender not be able to resist you."

(Kevin nodded as he takes the container and drinks it before getting on the machine. The door closed and the Test sisters began to work their magic on the experiment. Soon enough, the machine began to filled up with pink gas filling his lungs before opening a second later, letting the gas out as Kevin coughed as he exited out the machine.)

Susan: "Sorry about that, Kevin."

Mary: "Now, we have to wait tomorrow to see how you're holding up. So, head on over to bed and we will check up on you in the morning."

(Kevin nodded as he said goodbye to the sisters and went back to his room to get some shuteye.)

-Timeskip brought to you by Chibi Kevin sleeping on his bed, dreaming about him sitting on his throne while his Harem were fanning him-

(It was 6:45 am in the morning and the Test sisters are about to see how their brother is holding up.)

Mary: [knocks on the door] "Kevin, are you up? Susan and I are here to check up on how our experiment is doing."

Kevin: [from inside] "Yeah, I'm already up and ready! Come on in, the door's open!"

(Mary turned the doorknob, opening the door and the Test sisters walked in.)

Susan: "Okay, Kevin, we-"

(Susan and Mary froze as they blushed and have their eyes widen. The camera then shows Kevin's appearance as he is handsome and muscular, has 6-pack abs and a giant boner under his pants now. The Test sisters were staring at Kevin with lustful looks and they were drooling upon seeing his giant boner in person.)

Kevin: "You two are here to check up on me, right?" [No response] "Awesome, huh? I'm all buff and handsome thanks to your experiment. Normally I would just let you two go, but since you're here now. I thought that maybe you two could help me with this?"

(He strips off his boxers to reveal his huge boner and wiggles it around, making the Test Sisters's had nosebleeds and drooling over him now.)

Kevin: "Just by looking at your faces, you two don't want to be with Gil anymore and come to me instead, right?" [Susan and Mary just nods at him] "Awesome. Now with that outta the way, be good little sisters and pleased your little brother's cock for me~!"

Susan and Mary: [smiling lustfully and taking off their clothes; with hearts in their eyes] "Yes, dear brother~!"

(The Test sisters crept up to Kevin's boner and starts blowing their hot brother off, making the muscular boy to moaned lightly with delight.)

Kevin: "That's right, ladies. Blow me off with your sexy mouths. I'll give you lots of my white semen meal for you all to savor."

(Susan and Mary kept licking and sucking off Kevin's boner as a team and when they stopped, they wanted their brother to take their first time, which he accepts.)

~Starting Montage~

(First: Susan and Mary were holding hands as Susan was sitting on Kevin's face while he eats her and Mary was moving her hips, riding on Kevin's boner.)

(Second: Mary was on Kevin's lap on the edge of his bed as he thrusts her vagina in and out before climaxing inside her while Susan was on Kevin's side, making out with him erotically.)

(Third: Kevin pinned Susan against the wall pounding her insides from behind while groping and squeezing her breasts. Then he came inside her as well, which caused Susan to moaned loudly with joy. Meanwhile, Mary was seen fingering herself on the bed, moaning and enjoying the show.)

(Fourth: Kevin was sucking on one of Susan's nipples while he gropes the other, making Susan moaned crazily. Meanwhile, Mary was on her knees, sucking the life out of Kevin's boner with her mouth like a vacuum. Soon enough, Kevin came inside her mouth, making Mary gulped everything in her completely.)

(And lastly: Kevin was laying on his bed watching his horny genius sisters massaging his boner with their breasts. To even the odds, the sisters would take turns to lick and suck on a tip of his boner.)

Kevin: "Ahh! Hell yeah, ladies! Get ready! I-I'm about to climax!"

(Soon, he had reached his limit and gushed out his load on his sisters, landing on their faces, as the screen fades to white.)

~Ending Montage~

(Opening up to show Susan and Mary lying on Kevin's bed naked and their bodies filled with Kevin's semen, as their brother shot out some more at them a minute ago.)

Kevin: "Ahh! Now that was refreshing. Thanks for that, ladies. Maybe next time we do this again whenever we have free time. How does that sound?"

Susan and Mary: [dazed] "Yay~!"

(And so, everything fade to darkness.)

Episode cleared.
