Kevin's eyelids slowly pulled back as he came into consciousness. He groaned as he awoke from one of the best nights of sleep he'd ever had. Yesterday's orgasm completely drained him of energy and he slept like a baby. But since the pleasure had ended and his mind started to wake up, a sickening feeling started to come over him. He had gotten a blowjob from his own grandson. No matter how good it felt he couldn't rationalize it. What had happened was a mistake and he couldn't do it again. Though his mind said one thing, his body said another; as he thought about what happened he got hard. Picturing Ryan covered in cum looking up at him made him sick and horny at the same time. Kevin rubbed his eyes and groaned again, the stress of his situation was overwhelming.
"Morning sleepyhead," chirped Ryan as he poked his head in the doorway.
Kevin opened his eyes to see Ryan smiling brightly at him. His cock twitched as Ryan's cum covered face flashed in his mind. Kevin just groaned as he sat up in his bed.
"Breakfast is ready, do you need to use the bathroom?"
"No no," Kevin grumbled, "I'll be up in a minute."
"Kay," Ryan said as he left the room.
Kevin knew he had to bring it up but had no idea how, he was in brand new territory. There were no guidelines on how to tell your grandson he can't suck your dick anymore. Kevin got up and started his day as his mind searched for the answer. The day dragged on as normal as Kevin pondered what to say to Ryan. As the hours passed and shower time came closer and closer Kevin stressed even more, unable to bring himself to confront Ryan. The awkwardness and embarrassing nature of it all, plus his pride as a man, were keeping him from even acknowledging it.
Ryan didn't bring it up either. He could feel the tension from his grandfather and figured he was regretting what they did. But Ryan didn't. He loved every moment and was determined to continue their erotic affairs. He knew what he had to do, pleasure Kevin so well that he would break his own ethical code just to keep the pleasure going, and he was off to a great start.
The dreaded time came around and Ryan and Kevin headed to the bathroom. Kevin finally had the nerve, and was about to speak up when Ryan startled him by stripping down completely naked without a word. Kevin's eyes went down to Ryan's flaccid cock. He was long and smooth, tanned skin with a bright pink head. Ryan started pulling down Kevin's pants as Kevin found his voice again.
"Wait... Wait. We can't." Kevin managed to grumble out.
"What do you mean?" Ryan asked as he pulled down his grandfather's underwear and exposed his semi-hard cock.
"You know what I mean," Kevin continued as Ryan stood up.
Kevin's heart fluttered as Ryan moved in close to him. Ryan's toned abs pressed against Kevin's bulbous belly. Kevin got choked up having Ryan's face mere inches away from him. Ryan looked deep into his eyes and spoke softly.
"You mean when I sucked your dick and you came in my mouth?"
Hearing the words triggered Kevin, he started getting hard.
"What's wrong? You seemed like you enjoyed it. Don't you wanna do it again?" Ryan asked seductively as he slid his hand under Kevin's shirt and lifted it up so their bare skin was touching.
Both Kevin and Ryan's cocks were rapidly growing. Kevin could feel his heart racing as Ryan came on to him pressing his soft skin against his body. Ryan was a bit taller than Kevin, and as Kevin's cock raised up higher his shaft bumped against Ryan's head. Kevin winced, he knew what it was but he was frozen under Ryan's spell.
"N-no. It's... Wrong," Kevin sputtered out, "We're related."
"So what?" Ryan replied as he raised Kevin's shirt higher and circled a finger around his fuzzy nipple, "We're just having some fun. What's the harm?"
Kevin's body ran hot as Ryan teased him. He felt his reservations melting away as Ryan touched him. Ryan reached down and took his grandfather's dick in his hand along with his own and squeezed the rigid shafts together. Kevin's brain short circuited as he felt his grandson's cock pressed against his own. How easily his morals broke down when he realized just how attracted Ryan was to him. It felt good to be desired, especially in his old age.
"See," Ryan continued as he moved his face in even closer. "We both want it, so why fight it?"
Ryan moved in and pressed his soft lips against Kevin's as he gently stroked their cocks together. Kevin returned Ryan's kiss as he enjoyed the stimulation. Ryan pressed his tongue into Kevin's mouth and swirled it around as he continued stroking. Ryan moved back and pulled Kevin's shirt off before returning to the kiss and grabbing his old sagging pecs and teasing his nipples. Ryan was fully erect now and his cock poked against Kevin's belly as Kevin's cock hung under Ryan's and poked his ball sack.
Ryan was passionately kissing Kevin while Kevin was just barely returning them. He had never dreamed of kissing a man before and it was still awkward for him no matter how good the rest of him felt. Ryan pulled off his grandfather's mouth and kissed down his furry chest before taking a nipple into his mouth. He swirled his tongue around as he focused on Kevin's shaft and stroked him hard. He worked his nipple for a while before continuing kissing down his big hairy belly until he reached his cock. He looked up at Kevin who was watching eagerly and smiled before sucking his dick into his mouth.
Ryan rapidly sucked his grandfather's cock while he stroked himself. Kevin had to sit down as he nearly collapsed as his legs started shaking. Ryan quickly pushed Kevin over the edge and he once again shot his load down his throat. When Ryan had sucked Kevin dry he stood up and kissed Kevin on the lips and started to wash him. They washed normally and they went back to Kevin's room to put him to bed. Kevin's mind started to wander as he drifted off to sleep. Maria got him off too and that didn't mean anything, so was this really so different? The issues he had that morning didn't seem to matter anymore as long as he got to cum. After all it's just a blowjob, what's the big deal?
The pair had broken down a barrier and reached a new status quo. Ryan would give Kevin a blowjob during shower times, usually while fingering his ass, and jerk himself off. Over time it evolved as Ryan pushed for more. Flirting around the house, an ass grab here or there, a quick kiss. Kevin didn't reciprocate much except during their sessions, but Ryan was persistent. He started occasionally waking around the house nude or in his underwear. He'd sit on his grandfather's lap and stroke his chest as they watched TV. He'd grope Kevin's ass and crotch and bite his ear as he walked by him. Anything to try to make Kevin hard outside the bathroom.
And it worked. Kevin began getting hard from even Ryan's slightest touch. He had no control over it, the constant attention from his flirty grandson turned him on so much. He didn't think about it too much, just let himself enjoy the pleasure. Soon their sexual activities expanded outside the bathroom. Ryan would blow Kevin while he watched TV or jerk him off while he ate lunch. Though Ryan was enjoying their depravity, he was craving some stimulation other than his hand as well. And with what little effort Kevin put in to return Ryan's affection already, he doubted there would be any change in circumstances unless he acted.
The next shower that came around Ryan was ready. He had been regularly fingering Kevin's ass during their sessions and had worked his way up to two full length fingers. He knew Kevin loved getting his ass played with, he always came much harder when there were fingers inside him. Ryan just had to play into it more. He usually waited until he was playing with Kevin's cock, but this time he slipped a finger in as he was washing Kevin's backside. The old man groaned and leaned forward a bit as his ass clenched. Ryan pushed his finger in to his knuckle as he kissed Kevin's cheeks. He reached under and played with Kevin's balls as he finger fucked him and nuzzled on his fuzzy ass.
"Can you bend forward a little grandpa? I wanna show you something," Ryan asked sweetly.
Kevin complied and bent forward, putting his hands on the shower wall for support. Ryan pulled his finger out of Kevin's asshole and spread his cheeks apart. He leaned in and slid his tongue against Kevin's hole, feeling it pucker from his touch. Kevin had never felt a sensation like that before, he groaned as Ryan swirled his tongue around his tensed anus. Kevin reached down and grabbed his aching cock and started stroking himself as Ryan lapped away. Ryan pulled his cheeks ever farther apart and pressed hard against his grandfather, his tongue pushing through the tightened muscles into his ass.
"Aww fuck..." Kevin moaned as Ryan licked him from the inside, swirling his tongue around, exploring his grandfather's anal cavity.
Ryan tongue fucked Kevin's ass while he stroked himself. He pulled out and easily slid two fingers inside and started fucking him again while licking his crack and gently squeezing on his balls. Ryan's saliva dripped down and lubricated his fingers as he touched a third finger to Kevin's ass and squeezed it inside. Kevin continued to moan as Ryan slowly pushed it deeper and deeper until it met the others and he marveled at the tight pale pink hole stretched around them. He gently fingered Kevin as he compared the size of his three fingers to the girth of his cock, he could fit, he just had to convince his grandfather to let him.
Ryan removed his fingers and stood up. His cock poked against Kevin's ass cheek as he pressed their bodies together. Ryan leaned his head in and nibbled on Kevin's ear as he reached around and took hold of his dick. He began stroking his grandfather as his hips gently pushed the head of his cock against Kevin's ass again and again.
"I love your ass grandpa," Ryan whispered in Kevin's ear, "it's so fucking hot."
The words sent sparks through Kevin's body as Ryan picked up speed stroking him. Kevin could feel Ryan's cock prodding him but was enjoying his handjob too much to care. Ryan pushed more forcefully and his cock slipped under Kevin's ass and kissed his balls. Ryan slid his tongue into Kevin's ear as he grinded his dick on the underside of Kevin's ass. Kevin couldn't understand why it felt so good having Ryan rub against him but he didn't want to think about it too much. Ryan had other thoughts however.
"You always get sooo hard when I'm inside you," Ryan continued in a soft voice, "You just love when I put things in your ass don't you grandpa?"
