Letting the swirl of his forbidden fantasies and hot memories bounce around in his head, Mike stroked his morning wood a bit more before finally deciding not to jerk off to completion after all. As much as he enjoyed fantasizing about Lyla, he was much more interested in actually blowing his load inside her again, something which she herself had assured him would be happening again soon. Also, Mike reasoned as he groggily got out of bed, later that day his mom would be coming back home, and he was sure that she would be as horny for him as he always was for her.
The mere prospect of his beautiful curvy mother jumping his bones sent yet another jolt of arousal to Mike’s meaty shaft and broadened the grin on his face, causing a host of sexy mom-centric images to pop up in his head. Unbidden yet predictable, the thought that at some point he might have to tell his mother about having had sex with Lyla did pass through Mike’s mind, but he was glad to realize that he felt neither guilt nor fear associated with it. Deep down, he knew that his mom would understand and realize that his relationship with Lyla was simply evolving for the better, just like their mother/son relationship already had. In fact, Mike pondered, his mom would probably be happy to know that he and Lyla were even more intimate than before.
‘Maybe she’ll get turned on about it… I know I am!’ Mike thought, chuckling to himself as he sleepily made his way into the bathroom to take a strategically cold shower.
As he stripped naked and took a look at his rampant morning hard-on, Mike was tempted again to just stroke one out, but he managed to exert enough willpower not to do it, stepping into the shower stall instead.
Trembling under the spray of pelting ice-cold water, sighing as he watched his raging boner gradually deflate, Mike gritted his teeth and reminded himself that it was worth saving his cum for his sister and mother’s willing holes rather than waste it jerking off. If he played his cards right, he reasoned as his morning horniness evaporated and his erection wilted under the frigid shower, he might even get to fuck them both that very day.
“N-n-now th-th-that’s a w-w-warming thought!” he stammered to himself as he stepped out of the shower and toweled off, grinning at that naughty prospect even as he shivered from the cold.

Except for a couple of times when Lyla snuck up on him to teasingly push her round shorts-clad booty against his crotch and grind away while winking at him only to then cup his chubby cock through his pants and bounce away chuckling, the day went by pretty normally for Mike. Lori seemed in a better mood than usual, which he interpreted as a sign that she must have either hooked up with some of her high school girlfriends at her party or, even more likely, with Lyla later at home. As for Lyla, beside the moments when she teased Mike with her spectacular bubble-butt, she was her usual relaxed and whimsical self with both her twin and her little brother.
After lazing around by the pool for the better part of the morning and early afternoon, the three of them had a late lunch together, during which Lyla claimed the very last slice of their mom’s chocolate cake for herself by unapologetically stuffing it into her smiling face while her siblings were busy squabbling over who should have it and why. Once they finished straightening up the kitchen and washing the dishes, chores which fell mostly on Lyla as the chosen punishment which Mike and Lori agreed to inflict upon her due to the cake incident, Mike watched with a knowing grin as Lori whispered something into Lyla’s ear while grabbing her by the hand and dragging her away.
Under different circumstances, Mike would have thought nothing of it, what with Lori having always been kind of needy and prone to demand some alone time with her twin. Still, in light of Lyla’s recent revelations, he couldn’t help but wink and flick his tongue suggestively as he caught his curvy big sister’s bespectacled eyes. Giggling softly as she followed Lori out of the kitchen, Lyla just smiled back at Mike and made a funny face that seemed to say ‘Hey, it’s not my fault if I’m irresistible!’ while she left the room and disappeared upstairs behind Lori.
Chuckling to himself, Mike retired to his own room to chill. Still determined not to let his sexy fantasies get the better of him, confident that he would get a chance to put his dick to good use soon enough, he sat at his computer and opted to distract himself with some gaming.
With his headset on and his eyes glued to the screen, chatting back and forth with his online friends as he got more and more immersed in shooting stuff all over the place, Mike took little notice of the time flying by. In fact, he got so involved in the game that he was genuinely startled when he felt a light tap on his shoulder. Removing his gaze from the screen for the fist time in over an hour, Mike was not at all prepared for what he saw as he slowly and distractedly turned to his right.
“Wha… Whoa! Holy shit, Lyla!”
Gloriously naked, standing right beside him while facing away, Lyla was arching her back and shaking her epic bubble-butt right in Mike’s face, causing her big heavy tits to sway side to side as well. While she looked mischievously over her shoulder, Lyla couldn’t help but giggle at her brother’s awestruck, bug-eyed expression. In truth, the heavenly vision of his gorgeous sister’s curvaceous body offered to him like that, and particularly her soft plump asscheeks rippling and jiggling mouth-wateringly mere inches from his slack-jawed mouth, sent a jolt of pure lust coursing through Mike’s whole body, instantly making his cock stiffen to rock-hardness inside his pants and snapping him out of his gaming trance completely.
