Chapter 1
Tommy sat at his Father's laptop, browsing through his Dad's most recent internet history. He was 21 and thanks to his Dad's rather relaxed approach to setting passwords, finding the 'special' folder had never been difficult. Tommy wanked furiously and regularly to all of these treasures. He got an additional kick from using his parents' porn selection rather than the easier route of Googling his own.
He thought back to the day he first stumbled upon his Dad's collection. A bag of dusty old magazines and DVDs under his parents' bed. This was the first time Tommy had had his eyes opened to this wonderful world of filth as well as the realisation that his parents were sexual beings.
Over the following years, he started to take more notice of his parents' affection for one another. They openly exchanged lingering looks, kissed or gently touched each other all the time, which was enough to stir Tommy's ever growing lust. If he crept silently around the house, he'd occasionally catch his dad getting a feel of his Mother's ample chest, or her affectionately squeezing the crotch area of his Father's jeans.
He had also started to witness the effect that these little trysts had on them. The clear bulge in the front of dad's pants after he emerged from, "helping Mum in the laundry room." or his Mother's nipples pushing through the fabric of her t-shirt. A hunger started to grown in Tommy to find out if more was going on.
Since as far back as Tommy could remember, his Father had regularly teased his Mother about her snoring. When younger, he'd joined in, relating the noises he'd sometimes heard in the night. More recently, however, he'd woken one night with a raging hard-on. He could hear what he had previously recognised as the heavy rumble of snoring from the room next door. But as he concentrated more, he could hear higher pitched sounds and creaking usually associated with movement in their old house.
Tommy snuck swiftly but quietly to the door of his room. His cock throbbed as he recognised sounds akin to those featured in his Father's extensive porn collection. The low rumble was actually his Dad, grunting like an animal as he exerted himself, thrusting his cock deep into Tommy's Mum. He couldn't help touching himself, drinking in her reactions to this. She gasped and moaned gently, occasionally letting out a little exclamation like, "oh yes!"
Over the following couple of minutes everything got increasingly intense until he heard his mother squeal, "oh fuck Paul, I'm cumming!" and start unashamedly crying out as she orgasmed. This triggered his Father who went silent momentarily and then started groaning louder than ever as he shot an epic load inside her.
As they finished, Tommy slinked back into his room for fear that they might come out and catch him. His cock now insisted on immediate attention and he spent a mostly sleepless night processing this revelation, jerking himself into oblivion and cursing himself for not having realised what was going on sooner.
Tommy made it his mission over the next few years to learn everything he could about his parents' sex life. He used this information to try to lure them into being horny. These days, he took any opportunity he could to complimented any affectionate activity he witnessed, calling them things like, "a cute couple". He even tried to engineer them watching TV shows he knew would have sexual references just before they went to bed.
He still got himself off reflecting on one night after a party where his parents had both had a significant amount to drink. Tommy overheard his giggling, inebriated mother teasing his Dad with graphic statements like, "You've been desperate to see Mum's big tits all evening haven't you?" and "Look how wet you've gotten my panties." After a little while of this drunken play, she forcefully demanded his Dad, "get your big, fat cock in my mouth." and proceeded to give his father the mother of all blowjobs.
What followed was a short, but intense session accompanied with a commentary like nothing Tommy had heard before. Tommy lost two loads in a row standing right outside their door just thanks to the dirty talk alone. Working towards his third, he had to admire his dad's self-control.
From that night on, he often encouraged them to have an extra drink in the evening. Or he would offer to drive them all home from evenings out.
However, the most effective strategy for overhearing a good session was simply to lie about what time they should expect him home. He regularly sneaked home earlier than advertised to catch, "the late show," as he referred to it in his head.
Tommy discovered his parents had an extremely active and varied sex life. They usually got one another off in some way two to three times a week and Tommy was there on the other side of the door wanking along.
