Have some one on one "Bonding" time with his sister for the day

Author's note: If you want me to do more, I would love to hear your suggestions and your thoughts in the comments.

As Max placed his cock and balls on his sister's beautiful sleeping face, he began to think about what to do next. He could do whatever he wanted to her. Perhaps anal? Facial? Tit job? All were on the proverbial table for Lea to get fucked on. As Max's hands began to wander an idea came forth.

He wanted to give his sister a bukkake. When he watched bukkake porn, he always liked seeing women splattered with cum but didn't like the number of guys needed to do so. If it was humanly possible, he would've preferred if it was all one guy, but with the power granted by his new machine, this could and would be done.

Max had a sinister grin as he walked over to his room and typed in "What if I had unlimited sexual stamina and could cum as much as I wanted?". He then felt a tingly sensation in his balls as he could almost feel them filling. Max had a good morning after cumming twice at the family breakfast but now, he was much more horny than he was before. With newfound strength, he made his way to his sister's room. He looked at the clock that read 09:17, the sinister grin crept back onto his face as he closed his sister's door. Soon thereafter, the creaking of springs and the sounds of grunts and moans could be heard, broken by the occasional "FUCK" or "TAKE IT YOU STUPID SLUT!!".

2 HOURS LATER...

Max was done with her cunt now, as it was now red, loose, and seemed to be continuously leaking cum. It seems cuming 20+ times does that to pussy. Oh well, time to move on.

1 HOUR LATER...

Max was thoroughly enjoying breaking in Lea's virgin asshole. Showing that same lack of mercy her pussy was treated to. Max at one point told his **** sister "Wow, I bet you're REALLY going to feel this in the morning. I bet you won't even be able to walk tomorrow. Which means we can do this ALLLLL OVER AGAIN". He then wondered if his oblivious aura extended beyond his presence so that he could shove some vibrating dildos or beads in her and turn them on while he was away. Mmm, might be something to try later.

3 HOURS LATER...

Max was now straddled on top of her, freely using her tits to jerk himself off. He had gotten a little bored at this point at decided to spice things up by loudly watching some **** porn on Lea's computer. The sinful pleasure of using his sister's body like a fleshlight, coupled with the threesome porn with mom, son, and aunt, Max couldn't hold it in any longer as he sprayed more cum to coat his sister's face and hair before squeezing out the leftovers into her mouth.

2 HOURS LATER...

This was it, the final cumload was here. Max was jerking off using one of Lea's panties from the drawer. He had already coated Lea from head to toe, her skin glistening from the light of the afternoon sun. Max had to crack the window given the heat in the room from his constant fucking. If the neighbors weren't oblivious to Max's doings, they would have been given quite the show. Max stood next to the bed as he marveled at the piece of erotic artwork that was now his sister. As Max continued to pump his shaft he smiled at his sister's clothes drawers, he made sure to spray all her clean clothes and panties so that no matter what she wears she'll be wearing her little brother's cum.

As Max came for the last time into the panties, excess jizz dribbling down onto his sister's face. Mom knocked and poked her head in. "Hey sweeties, just wanted to tell Lea that I made her an early dinner." Hearing no response from Lea she then looked toward Max and smiled "Oh honey, have you been taking good care of your sister for the day?"

A perverse smile spread across his face as he said "Haven't left her side". Mom then said, "Aww, well when Lea's done with her nap tell her about dinner. Also, you may want to pick up some odor spray from the store, something smells funny". Max answered, "Oh that's just my cumloads I've been giving Lea, I'd be surprised if she wasn't at least carrying triplets right now". Mom then closed the door paying no mind to the filthy comment.

Max then placed the cumrag panties on his sister's face as he left the room, leaving the door open to let the stench of his cum permeate the house and for anyone to see his sister's cum stained body. Something came to mind as he made his way to his room and considered what to do next. While today was easily the best day of his life there were still more changes he could make. He went back to the machine and made the following changes:

• All pregnancies from Max's cum would result in girls

• No genetic defects would result from ****

• His cum would taste great for women.

• The average woman would be an 8/10 in terms of beauty by today's unaltered standards.

• Max's dad would receive a pay rise to $2000 or more a day so long as he worked hard.

With this Max looked forward to what he could do later. His dick hardened to that of diamonds at the thought of being able to have orgies with all his beautiful daughters. Daddy's little girl, or girls rather.
