"Do you really have to do that while I'm studying?"

Sitting at his desk with a math book open, Bailey frowned at his mother, watching her head bob over his step-father's lap. The two had chosen his bed to fool around in, getting a sexual kick from being nasty where her son would sleep.

"Shut up, dweeb," answered his step-father, a 23 year old named Steven who was only a few years older than him. Fit, handsome, and callous, the brash young stud was exactly what the older mother wanted after becoming a widow. Now she obeyed his every request, no matter how lewd, crude, or filthy.

"Listen to your step-father, sweetie," Donna added, rubbing the wet cock over her face as she looked at her son.

With the situation over a year old, Bailey had was used to seeing them together, even in raunchy situations. When he didn't object, they grew bolder, including him in their kinks and increasing his humiliation. While his room smelled mostly of cum, it was his clothing that received the most fluids.

Denied permission to wash them, Bailey had become a walking cum rag that Steven and Donna both used whenever they needed. Each shirt Bailey had was marked with load after load of jizz, leaving speckled stains that could be seen by anyone. Of course, his mother's cum was included too, but wasn't as noticeable as Steven's.

Even now as Bailey tried to study his shirt was wet in places, a result from breakfast when Steven pulled out of a cream-pie and fired his load across the table, hitting Bailey's chest and bowl of cereal. Having adjusted to such graphic situations the teenager wasn't very phased anymore, but as the day continued it became harder to resist his own growing arousal.

Wanting nothing more than to quit studying and watch them, Bailey bit his lip and continued, unable to ignore the sloppy sounds of his mother's mouth giving love to Steven's cock.

"Now lick my balls," the young step-father ordered. "I'll cum if you keep sucking me like that."

"That good, baby?"

"Too good," he chuckled. "You're always hornier in your son's room."

Bailey was rubbing his erection now, his eyes on the textbook but his mind swirling with devious and erotic images. If he stopped studying, his mom would punish him, but how could he resist?

"What can I say ... I'm a terrible mother."

Twisting in his chair, Bailey looked back to see his mom's face going under Steven's balls, clearly aiming for his asshole. Already laying on his side, Steven lifted his leg to give the milf better access, letting her tongue inside while she snorted the musk of his ass.

"Oh fuck, you know I'll cum if you do that."

Getting a rimjob and a handjob at the same time, Steven grimaced before spotting her son gawking like an idiot. Flipping him off, he could feel a pressure building inside his cock, and the stimulation from Donna's tongue working its magic on his prostate.

"Damn it," he grunted," you better get over here, loser, I need something to nut on."

Without question, Bailey abandoned his studies, racing to the bedside for a better view. Clear and stringy pre-cum from had started leaking across her hand, and with every deep thrust of Donna's tongue, Steven's cock throbbed harder.

"Sh-Should I take my shirt off?" Bailey asked, blushing as he rubbed the bulge in his pants.

"No time, gonna nut--"

Rolling onto his side, Steven's ass was still being rimmed as he masturbated, quickly aiming the head of his cock toward Bailey. Already at the bed's edge, the teen dropped to his knees so that his chest was level with Steven's cock, the stained shirt ready to receive yet another hot splash of sperm.

"Oh fuck, here it comes," Steven grunted, putting a hand on the back of Donna's head as he jerked himself faster. Giving a guttural moan, the young step-father's cock erupted as it had many times before, carelessly firing strings of cum in whatever direction it was aimed.

Bailey had learned over the last year, that one other reason his mother liked Steven wasn't just his youth or good looks, it was his virility. The first shot of cum went higher than expected, striking Bailey straight in the face with a wet slap before running down his neck. The next two shots splashed his neck and the collar of his shirt, while the next two went lower striking his chest.

"Good boy," Donna could be heard saying from behind, her face still buried in his ass, "let it all out for mommy."

Steven's cock continued to spasm even after his balls were empty, still trying to pump out every last drop. While most had hit Bailey, there was still a mess on the edge of the bed and floor, but of course it would never be cleaned up.

"Fuck that felt good," Steven sighed, feeling Donna's long tongue pull free of his asshole. Waiting on her to crawl up beside him, Steven swirled the spit in his mouth, and when he knew Donna was watching, he leaned forward and spit at Bailey's face, adding more liquid that slowly dribbled down his chin and neck.

Donna merely smiled, masturbating as she looked at her son. "Well? What do you tell your step-father?"

By now it was routine, and as Bailey's own cum seeped down the inside of his thigh, soaking his pants, he accepted his place and answered like he always did. "Thank you, sir."

"But I really like her," Bailey whined, looking up from the floor as he massaged his step-father's bare feet.

A few days had passed since the last session in his bedroom. His school work had resumed, and today he had been ordered to help his mother and step-father relax. With a small stool propping their feet up, and them both reclining on the couch, Bailey rubbed his fingers and thumbs into the underside of Steven's feet.

"That's why you should invite her over," his step-father chuckled, wiggling his toes in the teenager's face.

Finding it hard to resist, Bailey leaned forward and kissed the toes, feeling utterly humiliated as his dick gave a jolt. "B-But I know you," he complained, "you're just going to steal her from me."

"Does she like you back?" asked Donna, casually and slowly fondling Steven's cock.

"Yeah I'm pretty sure."

"Good, then invite her over for dinner … I'll make your favorite."

There was no fighting his mother once she made a decision, and while Bailey was terrified for the girl he liked to meet Steven, perhaps things wouldn't go that way. Despite the last girl he brought over, he was hopeful that Zoe would be different.
