This is part 2 of Liberty Joins the Party
*****
In the morning, we woke up and got dressed. It was a little awkward to start with, but by the time Liberty was ready to leave, we had had a good laugh and discussed all the things that we did the night before.
"Thank you so much for last night," Kate said to Liberty, "I can assure you that we both had the best night ever." She leaned forward to give her a goodbye kiss. It wasn't a peck, but a full snog.
"Maybe we could do it again sometime," Liberty suggested. "But next time, maybe we could get Greg involved? I'm sure he would love to touch and taste his mother like I have" she said, giggling as she shut the door behind her.
Kate's jaw nearly hit the floor. She had never openly admitted to wanting to fuck her son, but I had always suspected it was one of her fantasies. Here, it might just come true.
"Did you just hear what I just heard?" Kate asked me. "Did she just say what I think she said?"
"I think so, darling," I said, chuckling. "I don't know about you, but we've joked about it many times and the thought of it is actually a little steamy! How would you feel about it?"
"It's just so wrong," she replied. "As much as the thought intrigues me, I just don't think I ever could."
Often, Greg had left signs of pleasing himself, like crusty socks and tissues, but with this, Kate wondered if he fantasised about her. At this point, I had no idea that Kate would sometimes rub her pussy as she imagined watching the head of his cock thrusting up and down in his right hand as it wrapped around his huge penis, jerking furiously.
What shocked her was how much she hungered for the opportunity of watching her own son, as if a voyeur, biting her lips to keep from moaning. She often dreamed of standing outside his bedroom door in silence, as if she were watching a porn video, imagining the feast before her eyes, amazed that her son had grown into a strong man.
"How about you let me sexually role-play as Greg and see what happens," I suggested.
Kate blushed and giggled, but I could tell that she wanted to act this out! Seeing that devilish look in her eyes, knowing that Greg wouldn't be home until later, I took her by the hand and ran excitedly to our bedroom.
As soon as we entered, Kate turned, taking my hands in hers, whispering provocatively to me as if I were Greg, pulling me in tightly and grinding her hips against mine. My cock was beginning to respond, as she unbuckled my belt and opened my zipper. Slowly, she lowered my shorts to my ankles and helped me out of them as she tossed them into a heap beside my feet.
She moaned loudly as she then grabbed the waistband of my boxers, also yanking them to my feet. We were then all over each other, ripping the rest of our clothes off until we were both naked.
Her arms, wrapped around my chest squeezing her breasts, now bare, flat against me. Her nipples felt like stones, as she imagined them pressed against her son's chest. I could feel them getting even harder with her secret taboo desire. The room was silent except for her feline purring. My dick stiffened as she held me close. Her breathing betrayed her state of arousal, as my gasp for breath did mine.
She avoided my lips, teasing, knowing that when she kissed Greg, she wanted it to be exceptionally special. She began kissing the right side of my body, beginning with my already hard nipple. Her hot mouth on my ribs was pure ecstasy. She also avoided contact with skipped past my raging hard-on as her lips moved down my body, probably her way of also keeping me on edge, as she was fantasising, wanting, hungry to have this one occasion with her son.
Kate knelt before me. Her lips were on the front of my right leg. She tapped my ankles to spread my legs. Her mouth went to my sensitive inner thigh. My breathing was becoming hard and deep. I wasn't sure if I could stand the excitement much longer. She switched to my left thigh and placed firm kisses on it.
I was certain that I would spurt my cum any second, just like an inexperienced teenager, as she gripped my rod tightly with one hand and cradled my balls in the other. The pressure on my shaft brought me back from the threshold of cumming without wilting. Her tongue sensually encircled my balls. One at a time, she drew them between her lips. I was gasping for breath, yet her firm hand held my orgasm back. Her tongue went up my shaft from the root to the tip. She looked me in the eyes as my cock was taken by her beautifully soft lips. She seemed to be daring me.
"Oh mummy," I moaned, as I reached down to cup her soft tits, and squeeze her nipples. "Your naked body looks so sexy and beautiful!" Standing above her, still pretending to be her son.
Kate looked up at me, seductively smiling, but silent. She had never verbally admitted her sexual feelings for Greg, but I'd always hoped they were there. So far, it was only me that had alluded to the incest fantasy, but it was clear Kate was soon to allow it to take over.
"Come here and cuddle mummy," she said lovingly, giving in to her erotic lust to make this forbidden fantasy a reality
Kate lay back on the bed and spread her legs widely, imagining her son seeing her moist vagina for the first time. Her pussy lips were swollen from anticipation and appeared dripping with passion. Her clit pointed invitingly straight at my mouth, so I bent down and started gently licking her open slit.
Juices flowed freely from her hot pussy. After my tongue brushed the folds around her clit a couple of times, she became more vocal. "Mmmm! Mmmmm! Mmmmmm!" Kate moaned, as I continued to lap up her wetness. Her legs clamped against my head as she let out a purely human scream of ecstasy.
I then climbed on top, lying on her naked body with the head of my hard cock pressing against her pussy. I reached up to massage her breasts, pulling her erect nipples into my mouth, causing her to get goosebumps. As our naked bodies rubbed against each other, I teased her with the head of my cock, anxiously waiting for her to beg me to drive it deeply inside.
"Ohhhhhh, mummy, your body feels so sexy," I said. "I've wanked so many times dreaming about this opportunity to touch your naked skin like this," continuing to role-play as her son.
"Oh Greg," she groaned, wrapping her legs around mine and pulling me hard into her, forcing my hips into her mound and ramming my cock deep inside. Her pussy was soaking wet, allowing my cock to slip in deeply. "Ohhhhh fuuuuuck" Kate cried in pleasure.
I started pumping her quickly, like you would expect a young, inexperienced lover to do. "Is that okay, mummy? Am I doing good?" I asked, looking for reassurance.
"Yes, baby, just like that," she begged, "don't stop, you're going to make mummy cum."
I could tell she was getting fully stimulated, and so was I. My balls were filling and I was on the edge, ready to explode deeply inside her. "Oh mummy, I think I'm going to cum!" I cried, warning her.
"Give it to me, give it to me baby, give mummy your cum. Fuck mummy's pussy, feel how badly I want your cum inside me," she squealed.
That was too much for me, I couldn't hold on. Jets of cum came flying out of my cock, filling Kate's pussy. As my cock was pulsing inside her, she slipped her hand under me, brushing against my shaft with her fingers as she started to rub her swollen clit. I lifted my body to give her better access but stayed connected, holding my cock inside her. Her fingers went to work, rubbing her clit hard and fast. Looking at her face, her orgasm was building and it was clearly going to be a big one. This was the first time I'd witnessed her so squishy wet, thirsting for Greg, her own son, the centre of her erotic desire and it was amazing.
"Keep going, mummy, cum for me," I encouraged. Her breathing and moaning increased as I continued to flirt with her as Greg. "Oh, mummy, you are so naughty, fucking your son and making him cum inside you. Now it's your turn to cum all over your son's cock! You love it, don't you mummy? You love fucking your son's massive cock, don't you?"
This was exactly what she wanted to hear and then she fully joined in, "Oh yes Greg. Yes, mummy wants you, she wants you to be her lover. Oh Greg!" As her head arched back and her body completely tensed up, Kate jerked underneath me as the explosive sensation worked its way through her body.
I hadn't seen her cum like this in ages, clearly, she was loving this. We passionately kissed as I slid out of her, before lying side-by-side cuddling in bed, gently stroking each other. Kate gave me a nervous laugh, embarrassed, and said, "Wow, what have we just done?"
"Opened up another layer in Pandora's box," I replied. "I think you might have a new favourite fantasy; this could be the start of something really good."
"Hope so!" she replied.
*****
As the school term was finishing, Kate booked a two-bed house in the countryside for a nice holiday break. Originally, it was just going to be just the two of us, but Greg wasn't needed at work so she invited him and Liberty to join us.
The drive was a few hours away and when we arrived, it was plain to see that it was a bit isolated. There was a small village about a ten-minute walk away, but it only had a few shops, a local market, and a single pub, so it was obvious that we would need to create our own entertainment.
Over the first few days, we went on trips sightseeing, and generally lazed around, relaxing. However, running a little low on supplies, Greg and I decided to walk over to the village market to gather some additional bits and ingredients to make a special breakfast for the girls.
While we were away, Liberty confided in Kate that she had forgotten to bring her contraceptive pills. "Hope you were careful last night," Kate said, after having heard them rocking the bed springs the night before.
"I promise we were careful. I let him fuck me for a bit, but didn't let him cum inside me," Liberty informed her.
"So where did he cum?" Kate asked, quizzically.
