Aliza was sucking on the tip of the cock while Catherine was working her way along the shaft. "Mmnnn...that's right! You two are doing great!" Sterling enjoyed while sucking on Brenna's tits and playing with Mallory's pussy. Mallory and Brenna were tasting each other's lips.
"You're a great kisser, Brenna!"
"I learnt from the best brother!"
"Fuck, being part of this taboo relationship is turning me on!"
"Welcome to our world!" Brenna looked at Mallory from top to bottom. "Baby, do you mind if I have some fun with our guest first?"
"Do as you please, sis! You don't have to ask me for any permission!" Sterling winked at her as Brenna grabbed Mallory's wrist and dragged her to the other side of the bed.
"Huh, I've never been with another woman...other than Aliza!" Mallory was shrugging as she lay down slowly on the bed.
"Don't worry, I've had so much fun with Eva. I can impart my wisdom on you." Brenna pinned her hands and kissed her while crushing her chest with her breasts. She moved her body against hers as she was kissing.
Sterling turned his attention to the other two. "Cathy, Aliza I'm getting up." Sterling got up as he sat on the edge. Catherine knelt next to him while Aliza was standing up. "How do you want to do this?"
"Do you think you have enough to endure all four of us?" Aliza asked.
"I have enough training to minimise my refractory period. You're all getting my load one way or another." Sterling smirked as he sat comfortably.
"Then take this." Catherine climbed on the he'd on top of him as her pussy faced his face, she pressed it against his face for him to eat it while holding onto his head at the same time. Aliza used this opportunity to blow Sterling cock. Sterling started eating his sister's pussy while his aunt was bobbing on his cock.
On the other side, Brenna was tasting Mallory's nectar from her soaking pussy. "What...is this feeling...this is so much better than...fuck...where did you learn to please like this...aahhnn..." Brenna flicked her tongue inside Mallory's hole, making her quiver even more. She then got up and lifted her left leg. "What are you doing?"
"Didn't you learn anything from Aliza?" She placed her self next her lifted leg as her clit rubbed Mallory's vaginal lips. "Mmmnnnn..." Brenna held on to Mallory's leg and started rubbing herself against Mallory. "Do you like that, you self-centred cunt?"
"Fuck, Aliza help me! Your niece is breaking me!"
"Keep your eyes on me, slut!" She pressed her calf between her breasts. "Fuck, it feels so good! I've never thought I would enjoy fucking a woman other than Eva." She moved her hips using her knowledge to make Mallory scream like Eva but no one could scream like her. "Babe, we should make this a usual event!" Brenna turned her attention towards Catherine who was getting eaten by Sterling. She felt a little jealous then it turned into pride, she felt happy for her sister.
Sterling tapped on Catherine ass cheeks making her to stop. "Did I put too much pressure on you, Bro?"
"You were perfect, Cathy! I want to fuck one of you." Aliza looked up and checked out the whole room.
"Well, those two have already started it. You can start with Catherine!"
"Are you sure Aliza?"
"He promised he would take care of us all, right?" Aliza pushed Catherine onto the bed. "Now, I heard stories about your special sucking skills. Put that to some good use, will you!" Aliza climbed on top of her and placed her pussy straight next to Catherine's mouth. Sterling position himself next to Catherine's pussy and entered.
"Aahhh...!"
"That's my signal!" As soon as Aliza heard a moan from her young niece, she started grinding her wet pussy onto her mouth. Catherine put her tongue to good use as she enjoyed getting pounded by her brother. He spread her legs and thrust his length. To his surprise, Catherine was stretching it to ease his way and tightened it when he was inside.
"Wow, Cathy, where did you learn that?" She moved her right hand behind Aliza's back and pointed at a dildo on her desk. "Aw, you've been preparing your hole for me! That's so sweet, sis!" He thrust his hip as he admired Aliza's well-toned back.
Sterling leaned in a little and grasped her shoulders. "Hello, beautiful!"
"You two are fucking monsters!" Sterling looked down to see what she was implying. Catherine had her hands filled with Aliza's asscheeks. She was moving her body while flicking her tongue inside. This made Sterling even enthusiastic as he increased his pace. Catherine tapped on Aliza as she got up.
"I'm going to cum!"
"Soak my dick, my precious little sister!" Sterling moaned as he rested his head on Aliza's shoulder while she cummed for her turn on Catherine's face. Catherine cummed too while Sterling was resting his dick inside her.
"Wow...I can't even...put a sentence...straight, Aliza...you have a...delicious fucking...pussy!"
"Where did my...sweet little niece...go?" Aliza said as she leaned back on Sterling's left shoulder. "Let me rest a...little! You can go save...Mallory!"
Sterling looked at Mallory who was screaming on the top of ecstasy. He started stroking his cock and moved on his knees towards Brenna and Mallory. Brenna moved to the side as she saw her brother approaching. "She's all yours, baby!"
"Wait...don't leave me, Bren...oh Sterling, are you here to repay me?"
"I am but before that, Brenna, do you mind cleaning my dick? Mallory doesn't like getting someone else's juice inside of her."
"I should say no but it's Catherine's so I don't mind!"
"Aw...she loves me!" Catherine sent a flying kiss towards her sister and rested with her aunt. Brenna started licking Catherine's cum from Sterling's dick.
"Oh, Brenna, my love, please don't make me change my choice!"
"Hey, I take offence to that!" Mallory pouted.
"Oh don't be jealous, I love you all equally and..." Brenna finished cleaning her brother's cock. He then moved towards Mallory who was eagerly waiting for his hard cock. "...passionately!" Sterling entered her hole as Mallory moaned in her angelic voice. Brenna wrapped her arms over Sterling's chest and hugged him from behind. "Do you want to feel my rhythm?"
"No, I just wanted to hold while you fuck. It helps me be comfortable with this idea of sharing you with others."
Sterling adjusted his body with Brenna on his back and then he started fucking Mallory.
"AAH...I'm cumming!"
"What the hell...he just pushed once and she's already cumming?" Brenna asked as she was confused by what happened. Aliza and Catherine joined them. Aliza spoke, "Mallory is kind of addicted Sterling's cock. She cums a lot, I mean a LOT when they fuck."
Sterling fucked her while she was quivering on the bed. Catherine moved towards her breasts. "I want to taste these tits!"
"I don't think that's a good idea!" Mallory was reluctant.
"Oh, just let the girl have her fun. If it makes you feel any better, I'll join!" Aliza comforted her. Before Mallory could answer they were both on either side of her chest sucking and kneading on Mallory's milkers who didn't have any milk...yet. Brenna and Sterling watched this like as Brenna pushed her brother a little.
"Come on, baby! Pump in a little!"
"I just love how your breasts feel on my back. It feels like I'm being nurtured by angels."
"Kiss me!" Sterling tilted his head to the side to kiss his elder sister.
"Babe, I have an idea. Why don't we all give our attention to our guest?"
"You're a dirty bastard, you know that?"
Brenna moved to the side and crawled towards Mallory's face. She climbed on top of her head showing off her wet pussy. "Come on, Mallory! Now is the time for you to return the favour!" Brenna faced Sterling as Mallory started eating her hole. Her eyes started flipping as Catherine and Aliza pinched her breasts on their side. "Wait...this isn't what...I expected!"
"Come on, Brenna! You love it, don't you!"
"Except...I'm embarrassed that...you're seeing...me like this fuck...she hit the spot." Brenna extended her arms as Sterling helped her balance while still fucking Mallory at the same time. A couple of minutes later Mallory tapped on Brenna's ass. She got as Mallory was gasping for breath.
"I...ahh...I'm...the big one...is ...AAAAHH..!"
Mallory had a giant orgasm shaking off all the other women off of her.
Sterling who was holding onto her thighs survived and slowly removed his length from her. "Aliza, what do you say?"
"Well, I'm not high and might like this bitch, so give it straight to my pussy!" She made some space for herself standing all on her fours showing off her behind to her nephew. "Take me from behind!" Sterling went inside her, from behind as she let a loud moan. "Fuck...I should get used to that...but it still feels like the first time!"
"Same here, Aliza! You feel as tight as the first time." Sterling held on to her hips and started thrusting his cock in her.
On the other side, while Mallory was resting Brenna pulled Catherine into a kiss but this time it wasn't a friendly kiss between sisters, this was sexual. "I love that we got to the point where we don't have to hold back." Catherine smiled at her sister.
"Have you always had feelings for me?"
"You're my idol. It was impossible for me not to get aroused by your body!" Catherine juggled with her breasts. "I'm glad we did our first with him."
"I used to regret not doing with Vincent but now I'm glad."
"We can share the same man for the rest of our lives."
"Yeah, I'm beginning to accept it too. Thanks, Catherine, for initiating this!" Brenna rubbed the back of her right hand on her cheek.
"I'll stay with Mallory! You can go with them."
"Are you sure?" Catherine kissed her sister and pushed her towards where her brother and aunt were.
Sterling wrapped his arms around Aliza's waist and kept fucking her. After running his forearm on her belly, he lifted her up against his chest. "Fuck, that's even tighter."
"Let me stretch it out for you!"
Brenna joined them and crawled in front of her aunt. "Fuck, I want it so bad!"
Aliza looked at her as she was shaking from the penetration, and she threw her arms around her niece. "There you are, my beautiful Princess...who has the honour...of making me an aunt." Aliza was panting as she praised Brenna.
"It's been years since you called me that."
"I didn't know...you still like it!"
"It made me special in your eyes!"
"Oh, come and kiss your Aunty!" Aliza pulled her into a kiss sucking her tongue. Brenna kissed her back.
Sterling felt his first load about to burst. "Aliza, where do you want it?"
"Mal, he's going to do it!" For some reason, Aliza asked Mallory for permission.
"Go...for...it!" Mallory who still hadn't recovered showed her a thumbs up.
"Do it inside!" Aliza gave the green signal as the white fluid exploded inside her. Aliza dropped onto Brenna after all her exertion with her vagina filled with her nephew's sperm. "That was...awesome!"
Sterling looked at his cock and started doing a breathing exercise. Brenna slowly pushed aside her aunt and looked at her brother.
"What are you doing?"
"Reducing my refractory period!"
"Well, we can help you with that!" Catherine joined in with Mallory. Brenna and Catherine knelt on either side of his cock where Mallory was facing front. She started cleaning the tip while the sisters dragged along the side.
"Ahhhh...mmmm...this is heaven." Aliza joined in and started kissing her nephew.
"I hope you get back on for three more rounds!"
"Oh, Aunty, this is not my...first radio with multiple women. Catherine...can vouch for me!" As soon as Sterling mentioned it, Catherine showed a thumbs while she was sucking his cock. The girls cleaned up the cock which got hard again. Sterling didn't have to choose this time, Brenna was following her Aunty's path and already on her knees for taking it from behind. Sterling moved as the girls paved the way. He tapped on her asscheeks before entering her vagina. "Ahhhh...you were right, Aliza! It feels like the...first time!"
"Is it worth the wait, Bren?"
"You bet! Come on, baby! Fuck me!" Sterling started fucking her from behind as Catherine clinged onto his chest.
"Yeah, fuck her! Fuck her like the bitch she is!" Catherine was filled with adrenaline as she enjoyed her siblings sharing their special connection through sex.
"Huh...shut up, Catherine!" Brenna threw her arms to get a grip somewhere.
"Oh, what is going on, you fucking bitch? Can't take it anymore? That's right, you animal! I can take his length better than you can!" Catherine smirked as she winked at the other two, implying that she was only messing with Brenna.
"Keep talking shit like that...fuck...just like that baby, you can go even deeper." Brenna grabbed onto Aliza and used her to balance as she couldn't control her body with every thrust shaking her system. "I'm going to fuck you with Eva's strap-on, Catherine!" After, Brenna let out her secret about the toy, Aliza and Mallory's eyes started glowing. Aliza nodded at Mallory who ran towards the door.
"Where is it?" Mallory asked while she was unlocking the door.
"Under my bed...mmmm...there is a box!" Brenna didn't even look away.
"Wait, a strap-on? I'm not ready to get fucked by Brenna." Catherine tried to follow Mallory to stop her but Sterling pulled her into a kiss. Mallory was already gone when they pulled off. She even forgot to cover herself.
___________________
Mallory entered Brenna's room. She looked around at all the renovations that had been done to it and Catherine's giant TV that was shifted into her room because of the renovation in Catherine's room. She quickly looked under her bed and checked the box. After finding the strap-on, she then got up and realised she was completely naked. 'Fuck...what should I do?' She checked if Brenna had any clothes she could use temporarily but none of their colours pleased her taste so she grabbed a towel and wrapped it around her.
She quickly dashed out of the room and made her way towards Catherine's room. On her way, the towel dropped to the floor. Mallory didn't stop because she was too much horny to even cover her tracks. The towel fell in front of Ophelia's room which was slightly open. Ophelia opened the door yawning. She stumbled upon the towel and picked it up. Then she looked in the direction from which a peculiar sound was coming. By that point, Mallory was already inside Catherine's room but it didn't stop Ophelia from making her way towards it.
