Andrew couldn't believe what he was witnessing. Unable to form any words or thoughts, he stood by the door frame behind the wall looking inside his guest bedroom with door ajar. Soft sounds of slurping and moaning caressed Andrew's ears as he saw his lovely wife of 5 years, Jess on her knees sucking and slurping on a dick that wasn't his. As if it couldn't get any worse he saw that the dick she was blowing belonged to none other than his own father, Pete.

Andrew saw Jess and Pete in the mirror adjacent to the door, making sure he wasn't in view for either of them. Jess was smiling up at his father gagging on his dick. The sounds she made with her mouth were very soft but for Andrew it might as well would've been as if someone was ringing a bell straight into his eardrums. His heart was beating fast as he kept sweating all over.

Jess gagged, moaned, slurped Pete's cock like Andrew had never seen before. Pete kept giving her little compliments for her job. Andrew felt like crying but for some reason the tears weren't there. What was there was a feeling of something new, something indescribable. He should've barged in and questioned them but for some reason his legs refused to move and his heart made him watch them like a Peeping Tom.

"Fuck! That's some god crafted cock." Jess exclaimed as she made a loud slurp and pop on Pete's cock.

"That's some god level sucking as well." Said Pete.

Jess laughed at the comment and put her mouth on Pete's balls. Even from afar Andrew could see how swollen and huge his father's balls were, hanging loosely from a thick shaft twice as long as his. Jess sucked on his balls gagging while shaking her head making ponytail swinging left and right. She took his heavy balls out of her mouth and Andrew saw ropes of his wife's saliva dribbling down his father's heavy testicles.

"Oh god! That's it. I need to unload or I'm gonna go crazy." Pete said grabbing Jess' ponytail and shoving his long cock directly into her mouth. Jess opened wide and recieved the full length as Pete kept thrusting in and out, his balls slapping her chin. Andrew realised Jess was barley struggling and recieved the throat fucking more than well. He gulped feeling a stirr in his own jeans.

After a minute long hard throat fuck Pete took his cock out and Jess laughed once again wiping the saliva from her mouth and chin.

"Haha! Oh my god! You've really missed this, haven't you? Missed my slutty mouth and this thick body."

"Without a question. I've been so busy these past weeks, I couldn't find the time to come fuck you. And today I see you wearing this slutty dress, how can I not?"

"I'm glad you like the dress. Your son bought it for me. I do look like a complete slut in it. You were lucky enough to get hands on me before your son could. Not like he would've been able to do anything good to me wearing it."

"Yeah? You just needed this daddy cock to satisfy your hunger didn't you?"

Andrew felt ashamed hearing his wife and father talk about him this way. The dress was definitely slutty, which is why Andrew bought it for a special occasion. A black sleeveless bodycon with a deep V-neck to show ample cleavage and tie front and slit near waist ending in a ruffled layer right above her curvy bottom. It left very little to imagination about Jess' sexy body.

"Mmhmm. Yes daddy! C'mon, gimme that fat load from your thick daddy cock." Jess stroked Pete's cock softly and sensually kissing his tip.

"Yes, that's it. Churn my load out into your mouth."

"Fuck! I can't believe you are Andrew's father. Where the fuck did the genes even go?" Jess laughed.

"I don't fucking know, but what a disappointment. Anyways, shouldn't you be grateful you get to fuck this cock instead?"

"Mmhmm. Yeah. So grateful."

Andrew felt even more humiliated and wanted to disappear from the face of the Earth but was still stuck at the door peeping inside.

"I've an idea. Maybe we could get everyone together at your house tonight. You, me, James." Said Jess.

"Sounds like a plan." Replied Pete.

Andrew's eyes went wide. James? What the hell was happening? James was Jess' co-worker who she complained about so many times, one she claimed she couldn't even be around. Was it the same guy? She's been having an affair with not just his own father but her co-worker as well? This was too much. Andrew was furious. He stepped an inch closer and stopped hearing Jess speak.

"Want me to do that thing you love?" Jess asked.

"Go ahead. Make me empty those balls I've been aching from."

Jess put Pete's cock head in her mouth enveloping it all around her lips and started sucking on it fast and hard. She slurped and moaned softly into his cock looking up at his father who had his head back in bliss. Andrew saw his father's hard, veiny cock throb and twitch. He groaned and Jess started whimpering softly, still sucking on his head. He realised what had happened. Jess kept sucking and his father kept twitching for a full minute as Jess gulped and gulped all of his load down her throat. Andrew's jealousy knew no bounds. Jess had never really enjoyed giving him a blowjob, barely ever swallowed his cum but here she was, on her knees infront of his father swallowing ropes and ropes of his cum.

Andrew didn't know what to do. How was he going to make sense of this situation. The woman he thought was his life partner was sucking his father's cock. His father's cock. How could a father betray his son like that? Andrew felt his crotch getting tight inside the jeans. Was he... ? No way. Andrew was fully erect inside his tight jeans. Did he like this? So many questions surfed inside his head.

Jess got up and Pete gave her a tight hug. Jess gave him a kiss on his lips. Her black lipstick felt so inviting to Andrew even after everything he saw.

"Remember, tonight at your house."

"Take care of your husband and meet us ASAP."

"Don't worry, his little cock needs a minute or two if not a few seconds to burst and roll back into a slumber. I won't be late."

As much as Andrew hated hearing these words, a part of him realised how true it was. He was a 4 incher at best. Despite this, Jess had always assured him he was good enough, but apparently not.

Andrew scattered away and hid inside a bathroom on the upper floor while his wife and father went downstairs. He stayed there for a few minutes contemplating what step was to be taken next. Andrew couldn't look himself in the mirror. His cock was still throbbing so he unzipped his jeans and saw his precum stained underwear. All the images of his wife and father rolled back like a film reel and his cock throbbed even more. Andrew softly held his dick and started to pump it. It felt good. His breathing got quicker and he felt cumming within seconds when a loud thump at the door broke his concentration. He left his cock throbbing inside the tight jeans and zipped up to leave downstairs.

"Hey baby! Where were you?" Jess greeted him with a kiss on his cheek. Andrew felt his heart skip a beat. The lips which slurped up his father's cum mere minutes ago were now kissing him.

"Hey bud! Everyone's waiting for you. Time to cut the cake birthday boy." Pete told him.

Andrew gave an awkward chuckle and proceeded with cutting his cake.

"Happy 35th my boy. No matter how old you get, you'll always be small for me." Pete said to Andrew.

Andrew couldn't figure out if his father was making fun or being genuine. It didn't matter though. What he'd witnessed today changed his relationship with them forever. The only thing running through Andrew's mind was to sneak into his father's house at night and see what's about to happen.

Whether he was doing this to see the extent of his wife's betrayal or was this a newfound excitement, he didn't know. What he did know was that this gift he recieved on his birthday had not ended yet and it didn't seem to be ending anytime soon.

Part 2 will be out soon.
