Decchan's Laboratory

The Teacher suddenly makes an announcement, “We have a new substitute teacher today. Her name is Violet. Please listen to her as if she was your normal teacher.” With that the teacher leaves and in comes a woman. Shiro stares at the new teacher in disbelief. “Nee-chan?” she whispers. The woman looks over at Shiro and smiles gently. “Before I begin.” Starts Violet. “I would like to ask that Shiro Tsimki sees me after school please.” Shiro nods and the class begins.

After school, everyone leaves and Shiro rolls her wheelchair to Violet who is sitting behind a desk looking at some papers. “Nee-chan? Is that really you? You became a teacher?” Shiro asks as she looks directly at Violet. Violet looks at Shiro and smiles. “Yes. Your Nee-chan has finally come.” Shiro rolls her wheel chair over to Violet and Violet wraps her arms around Shiro and hugs her tight. Shiro buries her face in Violet’s shoulder as she clings tightly to her. Violet pulls away slightly after a few minutes pass. “You are as beautiful as always.” Violet says softly as she takes Shiro’s chin in her hand.

“And you are so amazingly cute.” Shiro blushes and tries to look away as Violet tells her this. Finally Shiro looks at Violet in her eyes. “I’ve always imagined… would you mind if I…” Before Violet can finish Shiro leans forward and kisses Violet softly on her lips. It was a soft and slow kiss, but neither wanted to stop. Violet wraps her arms around Shiro’s small body as she deepens the kiss. Violet licks Shiro’s lips slowly as Shiro clings to Violet wanting more. “Hehe, it seems like you have wanted it as much as me.” Violet says teasingly to Shiro. Shiro blushes and says “Nee-chan~”.

“Hehe, you are so cute when you blush. I love you Shiro.” Violet says as she kisses Shiro again. Shiro replies and says, “I love you too Nee-chan.” Shiro started moaning slightly as Violet kept kissing her. Violet slowly starts rubbing Shiro’s arms as she slides her hands to Shiro’s waist and rubs her stomach lightly. “Nee-chan” Shiro slightly moans. “We are at school?” Violet slides her hands along Shiro’s chest as she licks Shiro’s neck. “So? I locked the door. Do you want me to stop?” Violet asks Shiro as she keeps licking her neck. “But.. I..” Shiro pauses for a few seconds “No, don’t stop Nee-chan. Please don’t stop.”

“I’ll keep going then.” Violet slowly pulls off Shiro’s shirt as she starts to massage Shiro’s breasts. “Hehe, you are starting to grow some nice breasts. I wonder how they taste.” Violet slowly licks one of Shiro’s breasts as she rubs the other one. “Mmm~ so soft and cute” Shiro moans as she leans back in her wheelchair. Violet sucks lightly on Shiro’s nipple as Shiro put’s her hands on Violet’s head. “Hehe, how about we try a bit more?” With that, Violet starts to slide her tongue down Shiro’s chest as she kneels down between Shiro’s legs. “Shiro, I wonder what your sweet pussy tastes like~” “Why don’t you taste it Nee-chan~” Says Shiro, who was really getting in the mood.

Violet slowly undoes Shiro’s pants and start’s to slide them off Shiro. Shiro helps pull them off until she was left only in her panties. Violet spreads Shiro’s legs as she lightly rubs her finger along Shiro’s warm and slightly wet slit. Violet leans forward and licks Shiro’s pussy over her panties. “Nee-chan~” Shiro sighs as she runs her hands through Violet’s hair. “More. Please.” Violet licks Shiro a bit more before she pulls Shiro’s panties down to her knees. Violet uses her thumb and lightly rubs Shiro’s clit and pussy. “You are so cute down here too. I just want to eat you up~” Violet says to Shiro. Violet grabs Shiro’s legs and pulls her pussy to her mouth and shoves her tongue deeply inside Shiro. Shiro gasps and grabs onto Violet head as she gasps “Nee-chan!~ Yes!”

Violet curls her tongue slightly inside Shiro as she rubs her tongue up and down Shiro’s wet pussy. Shiro holds tightly onto Violet’s head as Violet keeps thrusting her tongue inside. Violet sucks lightly as she reaches up and rubs Shiro’s breasts. “Nee-chan… Nee-chan.. I’m…” Violet plays with Shiro’s nipples as she twists her tongue around and shoves it deep inside Shiro. Shiro was visibly gasping as she tightly wrapped her arms around Violet’s head. “I’m Cumming Nee-chan. I’m Cumming.” Violet keeps her mouth tightly over Shiro’s pussy as she squirts into Violet’s mouth. Violet swallows it all as she gently licks at Shiro’s pussy.

Shiro slumps down in her wheelchair a bit as she finishes Cumming. “Hehe, don’t think we are done yet Shiro.” Violet says as she slowly undoes her shirt and drops it to the floor. Violet rubs her own breasts a couple times before she pulls off her pants too and leans over Shiro and kisses her. “I hope you don’t mind sharing this with me.” Says Violet as she places her legs around Shiro and climbs into her wheelchair with her. “How would you like to suck on my breasts now?” Violet asks Shiro who was already grabbing Violet’s breasts and rubbing them. “Can I?” asks Shiro slowly as she looks up to Violet. “Yes. I would love it actually.”

Shiro then takes one of Violet’s breasts into her mouth and starts sucking on it lightly. Violet runs her hands through Shiro’s hair as she moans slightly from the stimulation. Suddenly, Violet feels something between her legs and looks down to see Shiro rubbing her pussy. “Nee-chan wants to feel good too right?” Shiro said teasingly as she slides her hand inside Violet’s panties. “Oh god yes. I want my lovely Imouto-san to make me feel real good.” Violet moans. Shiro goes back to sucking on Violet’s breasts as she slides a finger into Violet’s already dripping pussy. Shiro inserts a second finger inside Violet as she plays with Violet’s breasts and sucks on them. “Shiro… More… I’m so close…” Violet gasps as she reaches behind Shiro and rubs her soft butt.

Shiro fingers faster and sucks more as she leans close into Violet and rubs her body close to Violet. Violet looks down and brings Shiro into a passionate kiss as she cums from Shiro’s deeply thrusting fingers. “I love you Shiro!” Violet moans loudly as she tightly holds Shiro. Shiro pulls her hand from Violet’s wet panties and lightly sucks on her fingers. “Nee-chan~ you taste good.” Shiro says as she goes back to kissing Violet. “Hehe, how about we go home and we can continue?” Violet says as she goes back to kissing and holding Shiro. “I’m not sure I can wait Nee-chan~” says Shiro as she was already going back to rubbing Violet’s breasts. “Me either hehe” Replies Violet as she pulls Shiro into another embrace and holds her tight. “I love you Shiro.”

The Teacher suddenly makes an announcement, “We have a new substitute teacher today. His name is Ryan. Please listen to him as if he was your normal teacher.” With that the teacher leaves and in comes a young man. Shiro stares at the new teacher in disbelief. “Onii-chan?” she whispers. The man looks over at Shiro and smiles gently. “Before I begin.” Starts Ryan. “I would like to ask that Shiro Tsimki sees me after school please.” Shiro nods and the class begins.

After school, everyone leaves and Shiro rolls her wheelchair to Ryan who is sitting behind a desk looking at some papers. “Onii-chan? Is that really you? You became a teacher?” Shiro asks as she looks directly at Ryan. Ryan looks at Shiro and smiles. “Yes. Your Onii-chan has finally come.” Shiro rolls her wheel chair over to Ryan and Ryan wraps his arms around Shiro and hugs her tight. Shiro buries her face in Ryan’s shoulder as she clings tightly to him. Ryan pulls away slightly after a few minutes pass. “You are as beautiful as always.” Ryan says softly as he takes Shiro’s chin in his hand.

“Onii-chan?” Shiro asks as she looks into Ryan’s eyes. Ryan leans forward and kisses Shiro deeply before Shiro could say anything. His hands warming her body as he rubs her up and down. “Onii-chan~” Says Shiro as she kisses him back deeply and wraps her arms around his neck. “I’ve been waiting for this. But I’m sorry…” Says Ryan as he looks down. “Why?” asks Shiro. “Because it seems like I can’t wait until we get home.” He says. And with that he spreads his legs to show Shiro a bulge in his pants. “Do you want some help Onii-chan?” asks Shiro as she was already reaching to undo his pants.

“Yes please.” He says as he helps her unzip his pants and pulls out his big hard dick. “It’s so big Onii-chan~” Says Shiro as she firmly grasps his dick with her hands. She gently rubs it up and down as he gasps lightly. “Shiro. I want more.” With this he places his hands on her head and pulls her face to his dick. “Now please suck it Shiro.” She then takes the tip of his cock into her mouth and slowly traces her tongue around the tip and sucks on it lightly. Ryan guides her head as he slowly inserts the full length into her tight little mouth. His dick reaching the back of her throat as she tries to suck and lick around his dick. “Viowate me mwoar pweeze” Shiro barely says as she starts to pull her head up and down on his hot dick.

“Oh Shiro, don’t stop.” Ryan moans as he grabs her head and fucks her tight little moist mouth. Each thrust bring him closer and closer to pleasure as he finally grabs her head and shoves his dick deep into her throat and cums inside. Shiro swallows everything she can as he holds his dick deep inside her throat. Finally, she pulls her head back and let’s his dick slide out of her mouth.

“I love you Shiro!” He says as he kisses her deeply. “Now how about you let me give you a piggy back ride?” he says as he places his back to her. “Alright” she says as she climbs onto his back. He then walks around the room spinning a few times. “This seems sort of childish to me..” says Shiro while still holding onto his back. “Oh? Then what about if I do this?” He then brings her around to the front of him as he slides her panties to the side under her skirt and shoves his dick deep inside her.
Shiro gasps loudly and clings tightly to him. “Oh? You were quite wet to take me so deep.” Says Ryan jokingly. He then walks over to her wheelchair as each step thrusts his dick deep inside her wet little pussy. “Onii-chan… Onii-chan” she said as he took a seat in her chair. He then moves her around so it looks like she is sitting on his lap while his hard dick is still shoved deep inside her. He then slides his hands up her shirt as he rubs her breasts. Gently, he licks her neck as he starts to rock gently and thrusts his hard cock into her innocent pussy.

He licks her earlobe from behind as suddenly her pussy tightens around his dick and she lets out a mix between a gasp and a scream as she cums. As she leans back Ryan starts to move the wheelchair over to the desk. He then picks her up and bends her over the desk. “Hehe, we aren’t done yet Shiro.” He slides his dick out of her wet pussy and starts to rub it along her ass. “Yes Onii-chan. More. Ravish my little body please!” Ryan then grabs her hips as he places his tip along the entrance to her ass. Slowly he slides his dick inside. The tightness of her ass giving him shivers of pleasure. The wetness from her pussy acting as a lubricant to help slide the whole thing in. She closes her eyes and she enjoys the feel of his hard dick inside her.

Slowly, Ryan starts to slide his dick in and out of her ass. Each time he pushed it in he would rub her butt cheeks and kiss her back. Shiro tried to turn her head to kiss him so he helps turn her around while still thrusting his hot dick in her ass. He kisses her as he starts to thrust his dick into her tight little ass faster and faster. Their skin making a slight slapping sound as he thrusts into her. He kisses her deeply as he keeps thrusting his dick inside her. She starts to rub her pussy as he moves faster and roughly thrusts his hard dick inside her. She moans as he kisses her and plays with her breasts. “I’m about to cum Shiro. Where do you want it?” he barely gasps out as he keeps thrusting inside her ass as he lifts her up slightly. “Inside my pussy. Shoot Onii-chan’s semen in my pussy please!” she yells at him.

He then pumps his dick faster in her ass as he pulls it out suddenly and shoves it deep into her pussy. Her fingers dig into his back as she feels his burning dick reach the farthest depths of her pussy. She convulses as her pussy tightens around his dick. Unable to take it anymore he grabs her waist tightly and shoves his dick deep into her pussy and cums. Each thrust shoving his hot semen deeper inside her. Shiro clings to him as he fills up her tight pussy with his hot sperm. “I can feel it! I can feel Onii-chan filling me up!” she moans. She wraps her arms around his neck and kisses him deeply with her tongue until her climax slowly starts to go away. “I love you Shiro.” Says Ryan as he starts to slide his dick out of her. She grabs him and holds him close. “No! Stay inside me until we are home.” She grins at him. Ryan laughs as he picks her up. “Sure, but don’t think that means I’m going to make it easy for you.” And with that he starts to thrust inside her again until she feels herself cum once more.
