AN: Incest. Rough Sex. Next update will hopefully be quicker.

Slap. Slap. Slap. Slap.

The noise of flesh smacking flesh was heard resoundingly throughout the bathroom, punctuated by Sally's slutty moans.

"Fuckkk, Percy. Your dick is so big," gasping for air, feeling amazingly helpless being fucked against the wall in the bath by Percy. The water gave him more stamina and speed than possible for any mortal, and he put it to good use, destroying Sally's ass from behind with his thick cock.

"Goddamn mom; your ass is even tighter than your pussy. You like getting destroyed by me, don't you? Do you like feeling helpless?

"Oh fuck yes, I want you to slam into me as hard as possible! Cum in me, make me yours again baby."

Gripping Sally by her tits, leaving bite marks on her back, Percy started to fuck her in earnest, pushing her to her limit, the musky smell of musk and pre-cum filling the room.

"Fuck yeah, don't you dare sto-Wait, what was that?"

"Shit, I think that's Paul," said Percy, unconsciously still fucking Sally as he filled with dread at his step-dad coming home from work earlier than usual.

"Fuck Percy, we can't get caught! Go to your room now, before he comes upstairs! I promise I'll make it up to you later!"

Disgruntled, but understanding, Percy pulled out of Sally, but still smacking her ass to remind her of what he would have done given time, Percy quickly grabbed his clothes and ran out of the bathroom, cock-blocked by his step-father.

The rest of the day was uneventful, precisely the opposite of what Percy had wanted. Hoping to be able to fuck Sally during dinner, he was disappointed once again because they had to go outside to eat, and the chance of them being caught was just too high.

By the time they got home at 10, Percy was horny and angry, never a good combination. He kept feeling the tightness of Sally's pussy, pulsing around his cock, or her ass, which he loved to smack while pulling her hair and destroying her asshole. It made him incapable of doing essentially anything. Deciding there was no point in just waiting for her, and that they would make it up another time, he faded into a fitful sleep, opting to sleep naked, feeling hot because of his sexual frustration.

The warm wetness around his cock is what woke him up. Percy woke up, startled, immediately feeling something warm and sensual slurping on his cock, and quickly assessed it to be his mom.

"Fuck mom; that feels so good! Please don't stop! " said Percy, loving the way Sally's head bobbed up and down his thick cock.

Sally pulled her head off of Percy's cock with a loud plop, rubbing up and down his shaft with her hands while looking at him with sultry eyes.

"I'm so sorry Paul interrupted us, baby. Why don't you tell me everything you want to do to my body while I take care of this little problem?"

Sally immediately went back to sucking and worshipping Percy's cock and balls, slobbering all over it while fingering her soaked pussy, drenched at the thought of what Percy would do to her.

"First, I'm going to flip you over and smack your ass, for being such a bad bitch. It's past midnight, so you're late, and so you must be punished. Then I'm going to pound you into the bed until you're a puddle. Then I'm going to cum all over you." said Percy, grabbing Sally's hair and pushing her down onto his 9-inch cock, choking her, her eyes rolling up in enjoyment.

Not wanting to cum just yet, he pulled her off of his dick, looking at her with wild lust in his eyes. Before she could react, he used his battle-hardened reflexes and strength to grab her and flip her over, disorienting her.

"It's time I fucked you like Paul never could Mom. " slapping her ass and kissing her back.

"Please Percy, fuck me like a slut! All I think about every day is your cock in me. I want you to use me like a cumslut!"

"Only for you Mom, only for you," said Percy, as he took his hard cock, covered with her spit, and impaled her soaked pussy. Every time he would push into her and sheath his cock, her loud moans and jiggling ass motivated him to keep pulling out and slamming right back in. Percy had no care for whether or not Paul could hear them because the velvety heat Sally's pussy provided was worth any punishment in the world. Pulling on her hair to gain leverage, Percy started fucking her faster and faster, the sexual musk and squelching sounds of her pussy quickly becoming music he loved.

"You like this dick, bitch? Do I satisfy you better than Paul? Do you feel dirty for wanting your son's cock all day?"

"Yessss, oh Percy! I love you so much! I get wet just thinking about you, I can barely keep my hands off you whenever we're around each other. I love seeing you get hot and bothered whenever you see my titties. Ohhhh fuckkk, I'm cumming Percy!"

Sally's pulsating pussy was almost enough to push Percy over the edge, but he refused to come in anything, but Sally's tight asshole, a place only Percy was allowed to enter. It was his territory, and he declined to give it up.

Percy took his cock out of her vagina and quickly slammed into her tight asshole, making her scream because of the sensory overload.

"Oh fuck Percy, go harder! I want you to destroy my ass! I want to be sore for the rest of the weeeeeeek! FUCKKKKK!"

Percy gripped her hips like a man clinging to his life, cumming in spurts, leaving all coherent thought, gripped like a vise by Sally's asshole. His bronzed skin shone with sweat, as did Sally's giant ass, jiggling every time Percy slammed into her, red all over it, in the shape of hands. Sally passed out because of her orgasm and the feeling of Percy's cock in her, and Percy could not find the will or motivation to get out of Sally, so that's how they feel asleep, hoping Paul didn't notice Sally missing.
