Off course we weren't so lucky with the seating arrangement on the flight home; we had three adjacent seats, practically in the middle of the plane. Luckily, mom had pretty much drained me for some time and besides, my mind was preoccupied with Lizzy, whom – I was ashamed to admit – I had largely forgotten about during the entire holiday. Due to the late departure time, it was time to go to sleep by the time the plane had finally taken off; with the whole plane completely darkened, except for some minor orientation lights, we all drifted off to sleep pretty quickly.
In the morning, as the cabin crew started serving breakfast, mom was visibly irritated, horny and bored. After breakfast – it was still several hours before we were to land – my cock was almost bursting through my jeans. My mind wandered off as I couldn't remember the last time I hadn't pumped out my morning load: whether it was by my own hands or in either mom or Lizzy, I had always taken care of my morning erection. Even before, when Lizzy spent the night at my place and she wasn't in the mood, I always emptied my sack in the morning, even if I had to dump it on the floor or in a corner somewhere. This train of thought was not helping me with my self-control; I had an even bigger boner than before, which caused me to squirm uncomfortable; mom quickly caught on and smiled at me, whispering:"I am here for you, whatever you need." I could see, that although she had quite some literature and crossword puzzles to keep her occupied, mom was bored out of her skull and the only thing that kept her from attacking me was our seating arrangement.
I thought for a few seconds, then got up and reached in the overhead compartment, grabbing a condom from my stuff and clutching it firmly in my hand – not wanting anyone to know what I was doing. I made my way to the nearest rest room; as it had been occupied for several minutes, I feared an unwelcome smell when I saw a middle aged guy leave the small compartment. However, upon entering and locking the door behind me, I didn't smell anything out of the ordinary. When I glanced at the ground, I realized why: there was a big, fat wad of freshly ejaculated cum clinging to one of the walls, just above the floor; as it was still sliding down the perfectly smooth surface, I knew it had to be freshly squeezed. Apparently I wasn't the only one on the plane with a morning erection that had to be taken care of. I took out my big cock and pulled the condom over the tip, making sure to leave my shaft free. As I started beating my prick mercilessly, I thought of all the things I had done to mom over the last few weeks and all the things I still had in store for the little slut. I convulsed against the locked door and shot my morning load into the condom; after milking out every drop I could, I pulled the condom off my dick and held it in my left hand as I used my right to readjust my clothing. Before leaving the bathroom I held up the used condom and admired my significant morning load; it wasn't the biggest I had ever shot, but it was more than average. As I returned to my seat, mom smiled at me knowingly and glanced at my deflated crotch several times; as dad was looking out of the window, admiring the view from our current altitude, I sat down and looked mom straight in the eye, whispering:"Open up."
Mom glanced at the used condom I was showing her and a wide grin appeared on her face, then she opened wide and let me put the used rubber into her mouth. She closed and started swirling it around deliberately lewd and obscene. I leaned in for a second and said:"You like that, don't you, you fucking slut... eating my cum straight out of the rubber?"
Pupils dilated, chest heaving, she was extremely horny as she nodded her head affirmatively. I leaned back in my chair and just watched her for several minutes as she continued to suck and chew on the condom. As her nipples pierced through her blouse, she leaned closer and whispered:"I want you... hard!"
I whispered:"First chance I get, bitch!" and pushed her face away.
She shuddered with arousal as she closed her eyes and continued swirling my condom around it her mouth for another couple of minutes, sucking all the flavor out of it.
About twenty minutes later – I had already given up on trying something on the plane – dad suddenly got up and shuffled past our seats, heading for the restroom. This was the opportunity I had been waiting for: even as he was passing by my seat, I shifted sideways to give him more room to pass and put my hand on mom's left tit, wobbling it up and down as he moved passed my seat. Mom inhaled sharply and clawed at her seat, hardly able to contain her horniness. When dad was three rows away from us, I let go of her tit and put my hand under her summer dress, stuffing it in her white panties and wriggling two fingers up her moist cunt. Surprised by the brazenness of my actions, mom's face contorted with a mixture of intense pleasure and unbelief as my condom fell from her mouth, onto her dress and onto the floor. By the time dad had reached the bathroom, I had my two fingers knuckle-deep up mom's cunt. She was holding onto her seat as if it were a life vest, desperately trying to keep a straight face, just in case dad was to turn around and glance at her. Luckily there was no line for the restroom and he entered the compartment without looking back. As soon as the door closed, I started finger fucking her as hard and as fast as I could; unable to keep a straight face, her facial expressions were very entertaining as she focused her remaining energy on not screaming or moaning out loud. I really went to town on her and pretty soon she started lifting her pelvis up from her seat, fucking her lower body back at my hand. Unfortunately for her – and an added bonus for me – dad just had to tinkle and opened the door barely a minute after closing it... even in the savage way I was abusing her cunt, this wasn't enough time to make her cum. As soon as I noticed the door opening, I redrew my fingers, wiped them clean on her dress and pretended to be looking around the cabin; mom, sexually frustrated to her very core now, groaned and cursed as she readjusted her clothing and used every ounce of willpower to keep herself from stuffing her hand down her panties. Needless to say she wasn't pleasant company for the remaining duration of the flight, about an hour and a half: it seemed she grew hornier and more irritable the longer we stayed in the air! As we were landing and dad was looking attentively out of the window, mom leaned in closer and whispered, grinding her teeth:"If your cock isn't sliding in and out of one of my holes in exactly fifteen minutes, you're not getting near any of them for the foreseeable future, do you understand?"
I could tell mom was genuinely angry so I didn't argue with her and just looked at my watch; it was going to be close... it took eight minutes just for the plane to come to a standstill and another two for us to get our carry-on from the overhead compartment and join to line queuing for the exit. I only had six minutes left to get my hard cock into mom; there was no doubt in my mind that she meant what she said and although I had Lizzy to fall back on, I really wanted to continue abusing mom.
As we were walking from our gate to the main hall, I saw the first set of restrooms coming up on the right; with just three minutes left on the clock, I turned to mom and whispered:"Go into the disabled toilet... I'll knock four times, don't open up for anyone else!"
I walked up to dad and started talking to him, keeping him distracted long enough for mom to enter the restroom; then I said:"Hang on, I've got to take a shit."
As dad stopped and looked around, he asked:"Where's mom?"
Already moving towards the restrooms, I said:"In front of us last time I saw her... go on, I'll catch up with you guys at the conveyer belt."
I could see dad was thoroughly confused and not entirely convinced, but there was no reason for him to question me, so he turned and went on towards the main hall. A few seconds later, I knocked on the door of the disabled toilet and looked at my watch as mom opened the door: just over a minute remaining...
After she locked the door and turned around to face me, I grabbed her dress and just tore it off her; it ripped right in the middle, next to the line of buttons, sending them flying all over the little room. Before she could protest, I grabbed her bra and tore it apart, causing her saggy tits to bounce around. As she looked down at her bra in shock, my hands moved down to her panties, which I also tore off.
"Will you stop ruining my clothes, I have no..."
I didn't listen and just pushed her down to her knees, pinning her head against the door with one hand, as I took out my erect cock with the other, jamming it between her moving lips and sliding it in and out of her mouth a few times until she went quiet and started sucking.
Having made the deadline and with dad out of the way, I was free to use her anyway I wanted to.
Which was exactly what I was going to do.
After having her suck on my dick for about a minute, I said:"Take off what's left of your dress!"
Mom obeyed and threw her torn dress against the wall.
