When I met Kate, five years ago, she'd just joined as a teacher at the school I worked at. It was the only senior school in our small village, which all the local kids went to. She was married at the time, to a man who took her for granted. We were friends, and I heard how she was falling out of love, and how little he appreciated her. As they were growing distant, we started crossing the line, but only progressed further once she had initiated divorce proceedings. Kate lived with one of her sons, Greg, in a small house just out of town. They had always been close as mother and son. However, they seemed to have a little spark between them that stepped out of the mother-son boundary. The way that they looked at each other sometimes made me wonder if there were some hidden dark feelings underneath.
Recently, Greg had started dating a local girl called Liberty. As an 18-year-old couple, they were beautiful. Greg, blonde hair, blue eyes an amazing strong body, and a pack to die for. Liberty was slightly shorter but had long flowing blonde hair and the biggest curves you could see on a girl of her age. She was not afraid to show her curves, and often wore a low-cut tight dress to show off her fantastic figure. I was old enough to be her father, but she had been in my fantasies before, and I was partly jealous of Greg. However, I was more than satisfied as his mother's lover, and she ticked all my boxes.
Kate and I have a healthy sex life including role-play and dressing up. I'd always loved seeing her in sexy underwear and over the last year she had built up an amazing collection. We enjoyed acting out our friends and relatives when fucking, with her pretending to be people like her close friends or mother-in-law and me acting out as Greg's friends. She always had a thing for younger men, but all this had only ever been fantasy for us both. We had never done anything with anyone else, only role-playing, but it's something that we both enjoyed. When she could, she would "borrow" a pair of underwear from friends or her sisters and role-play them as we fucked. The thought of her wearing someone else underwear as we made love was one of my hottest fantasies.
Over the last couple of months, Liberty had spent more time around our house, with Greg often bringing her back after a night out. We were regularly seeing them both when they came home drunk from the pub, and often had a good laugh with them before they went to bed. I would always try to get a look at Liberty. When we said good night, I would make sure that I got a kiss and a hug before sliding my hand over her curves. Occasionally, I'm sure I had seen Kate doing the same, but we never confessed any feelings for her to each other. She hadn't come into our role play... yet.

One Friday night, Greg and Liberty came back drunk after meeting friends at the local bar. Kate and I were due to be out all evening, but we came home early after the party we were at finished early. They were not expecting to find us at home as they came in the front door. We were sitting in the kitchen towards the back of the house as they fell into the hallway. Through the paper-thin walls, we could soon hear them with their hands all over each other, thinking they were alone. The noise was clear, and we could hear their lips clashing and their hands fumbling. We listened for a couple of minutes, giggling about what they might be doing before Kate stuck her head up the door to say hi.
"Oh god, sorry," Kate said quickly pulling her head back into the kitchen. Her face lit up in embarrassment, as she shut the door behind her.
She came and whispered to me "Liberty's red coat was on the floor, her dress around her waist and Greg was sucking on her boobs." I was turned on instantly, thinking of that happening just metres away from me, but gutted I didn't get to see it myself. I could feel my cock getting aroused and kissed Kate passionately. She returned the kiss, and it was clear to me that we were both a little flustered about what had just happened.
After a few more minutes they appeared in the kitchen looking a little sheepish but drunk. Greg had a tight white T-shirt on showing off his biceps and pecs with Liberty wearing a stunning one-piece pale blue dress that now covered her boobs again. It was low-cut and didn't leave much to the imagination. Her bum and breasts were voluptuous, just bulging out of the dress. Her nipples were hard, from being sucked, and it was clear she had no bra on. She'd made my cock stand to attention so I didn't want to stand up. In the corner of my eye, I saw Kate looking at me. I had been busted checking her out but couldn't help it.
Kate and I were quite drunk too, but we continued to drink more in the kitchen with the two of them. The red wine was flowing and we drank some shots too, listening to music for a few hours. Kate grabbed my hand and had me up dancing and soon Liberty did the same with Greg. Kate held me close, and I could feel her sexy, curvy body on mine. My hands brushed against her ass, and she did the same to me. As we slowly spun around, we could see Greg all over Liberty. I couldn't blame him, she was stunning, but he was touching her up in front of his mother and her lover. One hand was permanently on her bum and the other hand kept appearing on her breast. "He is a very horny young man," I thought to myself. There was no way Liberty was stopping him either, she seemed to be loving the attention. In between songs, we all grabbed drinks. As Liberty went to take a swig, Greg's hand went towards her breast, knocking her arm, and spilling the red wine all down her front and over her dress.
"Greg!" Liberty shouted as she looked down, seeing her dress covered in wine.
"Quick, come with me," Kate said grabbing Liberty by the hand, taking her straight into the laundry room to get her dress into the wash.
Greg and I laughed, continuing to drink in the kitchen. After about five minutes, the girls reappeared, and Liberty was wearing one of my oversized shirts, that just about covered her bum. I wasn't sure why it took that long, but when they came out, Liberty looked a bit flustered, and Kate had a glint in her eye with a big grin on her face. It wasn't long before Greg and Liberty soon made their excuses and went up to bed, as Kate and I cleaned up for a few more minutes before following them up.
As we went up to bed, we could hear Liberty and Greg getting frisky. Kate was in front of me and stopped outside Greg's bedroom door for a second to listen in. God knows what he was doing, but it was clear that she was enjoying it.
"Oh, Greg just there" Liberty moaned.
Kate's eyes lit up, and her hand went to squeeze her breast. I would have loved to carry on listening, but Kate had other ideas and pulled me into our room. I sat on the bed as I watched Kate get undressed. Watching her stripping is always a turn-on for me, and I was soon playing with my cock as Kate got down to her sexy underwear. She walked over and straddled me, our lips meeting in a passionate kiss. My hands were gripping her sexy bum as I pulled her close to me. The feel of her semi-naked body against mine was so hot. As I lay back, we could hear the headboard from the room next door, starting to bang. The louder it got; the harder Greg must be fucking her with his big, hard cock. The cock that Kate had made. Liberty loved it and we could hear her moans getting louder and louder. The noise was turning Kate on, and as she climbed on top of me, she started to grind her panty-clad pussy over my hard cock. Her pussy was soaked, and I could feel the wetness leaking through her silk panties. Before long, she couldn't take anymore, pulling them aside and guiding my hard dick inside her. As I thrusted in and out of her, I felt her pussy getting tighter. Listening to her son fuck Liberty was sending her over the edge as she shuddered and came all over my cock. Her sweet pussy gripped me and spasmed around my shaft, with her love juices soaking me and dribbling out onto my balls.
"Oh my god that was so fucking hot baby" she said, before pausing and biting her lip. "Can I ask you something?"
"Of course, anything" I replied, curiously.
"Did hearing them fuck turn you on? Are you thinking about my son fucking Liberty, while fucking his mother?" she asked, while still sliding up and down on my cock.
"No darling, I'm too focused on you and your pussy" I lied. It was clear that we both were turned on by it, but we had never had them in our fantasies before and I was not sure if Kate was ready to have her son's name mentioned sexually.
"Oh, come on, you are, aren't you? You're thinking about Greg fucking Liberty's tight little pussy right now. I bet you are wishing it was you." She moaned as I resumed fucking her wet pussy. Her voice rose in pitch as she imitated Liberty's voice. "Mmm, Mr Dodgson," she purred, "You have such a nice, big dick! Give it to me. Fuck my horny little pussy with that huge, hard cock!"
