[Quest progress: 5/1200 pleasure points]
Alex curiously laid her eyes at her sister's crotch. Her finger was circling on the surface of Serena's opening. The ice cream was melting and slowly flowing away, that it dripped on the floor in drops.
Serena jerked her body as Alex was touching her gently. "Kyah, stop."
Alex gasped slightly, he looked at Tony. "Big brother she told me to stop."
Tony shook his head. "You only need to listen to me, got it? And you should now start eating the ice cream before it's gone."
Alex nodded with a firm look, she turned her face to Serena's groin and stuck out her tongue. She moved her head closer and had her tongue lightly brushed against Serena's caved opening, she was licking the cream off of it. She then smiled. "My sister is delicious."
Tony snickered as he stared at the scene. He couldn't believe that he was staring at yuri in real life. He clenched his fists hard as he was about to shed some tears. "I was freaking lucky!" He said proudly.
When he was done revering himself, he stared at Alex who was licking Serena. "Anyway Sis, don't you find her gross?"
Alex halted for a moment, she shook her head. "My big sister is perfect in any way." She returned her face on Serena and then continued eating her.
Tony could not take it any longer. His tiny soldier became erect and hard as steel. He went behind Alex who was on all fours. Seeing her glossy butt stuck out, he could not help but rub his shaft on her tight rose.
Alex gasped in surprise, she turned her head to him. "Keeeh, what are gonna do?"
Tony grinned at her. "Just continue what you are doing. This will help us with the case of your sister."
Her face was slightly dubious. "You sure?"
Tony guffawed. "A hundred percent sure!"
Alex continued what she was doing. Hearing Serena moan steadily, Tony wanted to hear another one. So he began inserting his rod with the tip first. Her tight labia spread out as it gave a path for his thick shaft to pierce through. Alex's jaw fell as she let out a sharp squeal.
Tony panted for air as he proceeded, since the tip was now inside her, slowly and easily, he let the lower part of his shaft crawl into her flesh. As his spear was jostling against her walls, Tony could feel the pleasant warmth and bumps inflicted upon his meat.
Unlike any other's walls, Alex's tunnel felt narrow that he could feel his meat might get crushed any second.
Alex rested her head on Serena's groin, she was drooling and her saliva fell on her sister's crotch. "It's tearing me apart"
"Don't worry, I know you're strong and you can take this." Tony leaned closer, he hugged her back and had his arms clasp upon her flat chest. He rubbed them slowly with his fingers.
When he was ready, he moved his hips away and his cock was grinding against her insides. Afterward, when he got the momentum, he began pounding her ass cheek with his hips. It was a slow thumping since Alex was incredibly tight that he could not sway his hips freely.
Alex did not have the strength to do her task and just leaned upon her sister.
Seeing her, Tony halted his movements for now and let his rod dwell inside her cave. "What's wrong Sis."
"It's draining my strength." As her face was bright red, she began to pant hard.
Tony was in dismay since his farming was a bit slow because as he was pounding Alex she could not do her job well. He checked the stats on his screen.

He noticed he still had a long way. He first pulled his meat out giving a lewd and squishy noise. Her hole tightened back into a slit.
Tony stepped back for a moment as he thought for a way that would please both of them. When a brilliant idea popped up inside his head, he grinned widely. He went closer to Serena and motioned for Alex to move away.
Alex complied and sidestepped. Tony sat on the floor and Serena's groin was now in front of his nose. He turned to Alex and smiled. He patted his hips. "Well then Sis, you should sit here."
With some hesitation, Alex gave a single nod and walked slowly towards him. He then sat down on his thighs and she was facing Serena's butt.
Tony swallowed his saliva as he aimed his shaft on Alex's entrance. As it roved around the labia, it finally stopped when it reached the middle part. He then pulled her close and penetrated her, his shaft drilled into her womb. A wild scream escaped her mouth, she tilted her head up and her face became dazed.
Tony gritted his teeth as he felt his cock was being strangled. The pleasure he was taking was too much, but he managed to compose himself and gobble Serena's groin. He licked her opening, letting his tongue enter and travel across the pink areas. With a drench and slurping noise, Serena gasped for air, slightly shaking.
Pleasure points were pouring in but it might take a while. So he just enjoyed the scene for now. As his tongue was rubbing against the outer walls, he spread out her labia and began sucking her cute and glossy pink erected clit. With a loud slurp, he also used his tongue to slap upon it repeatedly.
Serena loudly yelled. "No, not my clitoris."
As it went on, both of them screamed simultaneously in a symphony of a moan. Tony pulled his rod out as he burst fire, letting his sister bathe upon his thick jizz. Then on his face, Serena spat her slimy fluids.
With exhaustion, both of them hugged Serena, their bodies leaning upon her. When Tony realized that both of them were touching her, he got startled. Looking at Serena, she gasped. "Hey idiot, is that Alex?"
Tony winced a bit. "Oh crap." Staring at the stats screen, he was not satisfied yet.

It was probably the end of his quest right now since Serena was squirming around persistently until the blindfold slid from her eyes. When she saw Alex hugging her butt, her eyebrows knitted towards Tony. She then growled. "Put me down." Her voice was still but enraged.
When Serena was finally on the floor and without ropes on her, she crouched and took a look at Alex's reddened pussy lips. She sneered upon seeing it.
She stood up, crossed her arms as she stared at Tony. She took the glasses from her pocket and placed it on her eyes. "Hey idiot, I can't believe you did that to our little sister."
Tony chuckled nervously. "Calm down Sis."
"Whatever, we are done." When she was about to walk away, to her surprise, Alex was grabbing Serena's arm. "Umm Big Sis, I'm still feeling tingling down here. I think I still want it."
Serena stared at her with eyes of concern, but behind her, Tony grinned. When Serena turned her head at him, his face went stoic as he whistled playfully.
She snorted in annoyance and went close to Alex. "I see that you're not satisfied yet, but don't ask for your brother's penis. It will bring you bad luck."
"Eh, really?"
Serena nodded.
"But I won't be able to sleep if I can't get this feeling off of me." Alex shivered slightly.
Serena sighed as she bent her head low, she glared at Tony. "Look what you did to her moron." She said belligerently.
Tony then snickered. "I have an idea, why don't you help her Sis?"
Serena got startled. "Me?"
"Of course, don't you see that she is asking for help."
Serena gasped in annoyance. "Another one of your fantasies huh?"
Tony guffawed menacingly. "She is asking for it not me."
Serena snorted, she guided Alex to lie down on the bed. Alex sat down while Serena was in front of her legs. She then smiled warmly. "Okay Alex, let your big Sis see your cute vag."
She nodded and spread her thin and fragile legs. Serena readjusted her glasses, her finger was touching her puffy labia. "It's so smooth and soft that I'm kinda jealous."
Alex cowered as she squealed in response.
Seeing her, Serena gasped in concern. "Are you okay?"
Alex then grabbed her arm. "Sis, I'm feeling kinda weird, could you put it inside?"
Serena silently complied, she licked her fingers first, drenching it with her saliva. She directed it into her entrance. "Here it comes." Her nail intruded first, making its way until the entirety of her index finger was now inside her.
Serena held her glasses as she inspected it carefully. "Your vagina is eating my finger. So this is what it feels like"
Alex then hugged Serena's face. "Sis it feels good, please move it."
Serena gave a nod, her finger moved to and fro from her tight cave hole. Her slimy fluids were sprayed every time she performed a thrust with her finger.
Tony snickered as he just observed on the sides. "All according to my plans!"
