After that night, there was no more need for pretense, and Justin and I started living as if we were a couple instead of mother and son. He still called me Mom and we were very cautious around other people, but when we were alone, it was a different story. We eventually made love in every room of our house, and in every conceivable position. Justin still had not talked to Darcy yet, but he had broached the subject of another woman with her, and he said she wasn't against the idea necessarily. She hadn't seemed overly eager, but nor was she turned off by the idea. In fact, he told me he had described a fantasy to her while they were making love and it seemed to get her more excited than usual. That was encouraging news to me, as I found the idea of sharing her with Justin more and more enticing. The idea of being with another woman was something that never would have occurred to me in the past, but after watching my son with Darcy for so long, I knew it would be a phenomenal experience for all of us. My only concern was that it might frighten her and make her break things off with Justin, and I didn't want to see that happen. He kept reassuring me that it wouldn't, but I was still concerned.
Whenever Justin brought Darcy to the house, I tried to spend some time with her, hoping to catch her interest in some subtle way. I complimented her often, but not so much that it seemed insincere. I meant each one I gave her, and she seemed appreciative of them, and paid me some back as well. She was such a sweet girl, and I could tell she wanted my approval of her. She really seemed to care about my son quite a lot, and that made me love her all the more. Anyone who made Justin happy would make me happy. I was very affectionate with her, touching her arm or hugging her when the opportunity arose, and she responded happily. Feeling her firm breasts pressed against me as I hugged her excited me, and I could imagine her bare skin pressed against my own, as my son caressed us both. I longed for her naked between us on the bed, being teased and pleasured until she screamed out in joyful orgasmic passion. When I peeked at the two of them in the den, I wanted to lick Justin's thick cock as it slid smoothly into Darcy's pretty pussy. I wanted to slide my tongue over her clit as he fucked her. I wanted to share my son's cock with her, each of us licking and sucking on it together. Just imagining all those things and more made me masturbate furiously as they fucked on the sofa.
As Justin slid slowly into my pussy one night after Darcy had left, he spoke softly. "I've rented us a cabin in the mountains next weekend, my love. For you, me and Darcy." My pulse quickened at those words, and I gasped in pleasure as he began to lightly pinch my nipples. "I thought we could take a bottle of wine and just spend the weekend together. It's very isolated there and very beautiful. I think it might be easier to convince her if we're in a new setting. She may be more willing to try something new." He leaned over and kissed me deeply, continuing to stroke slowly in and out of my gushing slit. "Would Mommy like to fuck sweet Darcy with her sonny boy?"
"God, yes, Justin. You know I would."
"I want to share her with you, Mom. I want to see you eat her pussy and watch you make her cum for you. That would be so hot. I want you to make her so horny she begs for it." His thrusts grew harder into my pussy and he started licking my nipples and then sucking on them, as I dug my nails into his back, scoring it lightly. The idea of his mother and his girlfriend together sexually was making my boy more aroused by the minute, and very soon, he gushed forth into my pussy, shouting my name. I felt my own wave sweep over me and rode it to the crest and back down. As we lay together afterwards, I touched my son's cheek softly.
"Have you talked to Darcy about the weekend yet, sweetheart?"
"Not yet, but I will tomorrow. I wanted to make certain everything was set before I mentioned it. I think she's going to love the idea."
Justin was right as usual. Darcy came over that night and ran into the kitchen and hugged me tightly, her nipples extending the front of her thin t-shirt. She had no bra on and I felt my loins dampen with excitement, thinking of how easy it would be to touch her almost bare breast as she hugged me. She was fairly dancing with excitement and her eyes sparkled with joy. Her enthusiasm was catching, and I found myself laughing with her.
"Oh, Casey, I'm so excited! I can hardly wait to go. Justin is so sweet to surprise us this way, isn't he?"
"Yes, sweetie, he is. He loves coming up with surprises. You just never know what he'll do next!" My words had hidden meaning, but of course, she had no idea.
"I'm glad you're going with us, Casey. After that awful thing at the party, you need to get away."
"Well, thank you, Darcy. I'm glad too, and that you don't mind sharing Justin."
"Of course not! I think we'll have a great time." At that moment, Justin entered the room, and came over and hugged her to him, winking at me above her head. I smiled back and nodded.
"Well, come on, pretty girl, we need to get going. See you later, Mom." My son blew me a kiss and away they went.
After they had departed, I went upstairs to look through my clothes and find the sexiest and most appropriate items for our weekend getaway. I wanted to arouse and entice both of them with my body and my clothing. After sorting through my things, I had picked out items that pleased me and looked best on me. I pulled my suitcases out of the closet and set them out to air a bit. I was restless, and found myself dwelling on the feel of Darcy's delicious body pressed to mine. She was so sexy, and Justin was always telling me now how sweet she tasted. I could scarcely wait to find out. I found my pussy throbbing with need, and I knew I couldn't wait for Justin to get home later. I needed relief now. I lay down on the bed and ran my hands gently over my body, enjoying the feel of my fingers. I slowly unbuttoned my blouse, teasing myself, pretending that Justin was directing Darcy to do so. I could easily imagine him urging her to open my blouse and bare me to their sight and to their mouths. Perhaps they would share me as well. That thought was so arousing, I found my hand inside my panties quickly, sliding over my clit and rubbing it until I was screaming my pleasure aloud. The weekend couldn't come quickly enough for me! It was only two more days away, however, and I knew time would pass before I knew it.
Of course, I was right. Friday had finally arrived, and so had Darcy with her single suitcase. Justin put it in the trunk of the car as well as our bags, and then we were ready to go. I had Darcy sit up front with Justin and I had the backseat to myself to stretch out and relax. We were all in very good spirits as we drove along, chatting easily and sometimes singing with the radio. There was plenty of easy laughter and a feeling of warmth in the air. At times, I sat forward to talk to the couple more easily, and when I did, I slid my hand onto each of their shoulders to steady myself, lightly caressing. Again, I was tempted to move my hand to the swell of Darcy's ripe breast, but I refrained. There would be plenty of time to coax her this weekend, and I hoped things would go the way we hoped. I didn't want to force this lovely young woman, but I was also in great need of at least tasting her pussy just once. I hoped that we would be able to arouse her enough that she wouldn't want to say no. We stopped for dinner along the way and a short time later were back on the road. As the evening's gloaming began, we pulled into the long driveway that led to the main office and then branched off into the woods, breaking off into smaller roads that led to the cabins. Justin had reserved one nearest the river that ran along the rear of the property. There were no other cars when we pulled in, and Justin popped inside the office and checked us in. He came back out with the key and soon we were parked before a lovely log cabin known as 'River's Edge'.
"They name all the cabins here," Justin explained with a grin.
The cabin had a roofed front porch that held a swing and a couple of rocking chairs. We entered a living area with a fireplace, comfortably furnished with a pillow-covered sofa, a coffee table and two easy chairs big enough for two people to sit in easily. Lamps were scattered about the room, giving it a homey feel. A stairway just to the right of the entrance led to the upper floor. An open doorway near the rear of the room led to a kitchen complete with all the accessories. A sliding glass door behind a table and four chairs would show a lovely view of the river in the daylight. There was a stocked pantry in the kitchen as well. Walking upstairs, we found two large bedrooms. They contained king-sized beds with fluffy comforters and pillows piled high. The bed in the master bedroom was a canopy bed, with a sheer white canopy fastened to the bedposts. It could easily be let down if one wanted to sleep behind it. The other bed was a sleigh style. Both rooms contained two nightstands, each holding a lamp. The closets were ample and there were dressers in each room as well. Each room had its own bath, although the tub in the master bedroom was a large jacuzzi tub. I had a picture flash in my mind of the three of us in that large tub together, and felt myself get wet immediately.
