Chapter 4 – Tuesday the fourth day. As had happened in the past two mornings I woke before Cassie and had a quick shower. Once I was dry I went back into the bedroom. As I had done yesterday, I woke her up by blowing on her nipples and teasing them with my tongue. "Oh that's such a wonderful way to wake up." she said. "Are you going to move in with mom and me when we get home so that you can wake me up that way every morning?" I laughed. "Sorry, this is a 'Cabin Wakeup' only. You'll have to wait until you get back out here with me again." "Meany!" she said with a big smile then jumping out of bed, ran to the bathroom to have a pee. "Jump in the shower and I'll get breakfast ready" I said. "Aren't you going to shower with me?" "Nope, not this morning. I already had my shower." "Aww!" While Cassie was getting cleaned up I got breakfast ready and when she came out, we sat down and ate. "Are we going to have another lesson today, Uncle?" "Yep, but not until tonight. I want your mom here for the next lesson." "What are you going to teach me?" "You'll have to wait and see. Did you think of anything that we could do to surprise your mom?" "Mmm... not really." she said. "Well About the best I can think of would be to push the couch around so that it faces the door then sit on it, naked when your mom comes in. It's pretty lame, but that's about all I can think of." "That's okay, maybe we'll think of something else by the time she gets here." Cassie said. The weather was a bit cooler today so we decided to forgo the pond and stayed inside. I dug out a jigsaw puzzle and we worked at that some and we played a couple of board games while also doing some surreptitious grabbing of various parts of each other anatomy. Soon it was lunch time and I told Cassie that we'd better get things ready as we couldn't be sure exactly when her mom would arrive. We put the board games away and rearranged the furniture then had some lunch. We'd no sooner finished lunch that the security system beeped to let me know the gate had been opened. I looked at the monitor and confirmed that it was Sandy. "There's your mom." I said. "Hurry up and let's get seated on the couch." Cassie complied and we sat with my arm around Cassie. I took hold of one of her breasts and she reached out and grabbed my cock. "Let's spread our legs out so she can see our 'private parts'." We'd just nicely got settled when we heard a car door close and a minute or so later the door to the cabin opened and in walked Sandy and suddenly stopped with a surprised look on her face. "Oh what a wonderful sight!" she exclaimed smiling from ear to ear. Setting down her bag she immediately started to undress. When she was naked like Cassie and I, Sandy came over and sat down beside Cassie, hugging and kissing her. "Sweetheart, I'm so glad you're looking like that. You've obviously enjoyed Uncle Harry's lessons." "Oh Mom", Cassie said, "Uncle Harry has been so wonderful. At first I was afraid but now I know that he'll never do anything to hurt me. I haven't had my lesson for today as Uncle said we had to wait until you got here." Turning to me, she asked "Can I have my lesson now?" "Today's lesson is very special and we'll wait until after supper. Let's put some clothes on and show mom the pond." "Oh wow, Mom, the pond is so neat." Cassie said. "We've been up there swimming yesterday and the day before and if it gets warmer, we'll go back again. We've been skinny dipping in the pond - do you know what that is?" "Of course, dear. Your uncle and I used to do that when we were about your age" Sandy said. Cassie's eyes got big. "Mom! You didn't! Wow! I never thought that you had done that." "Well you remind me of myself when I was your age. I enjoyed skinny dipping just as much as I suspect you do. Let's go see the pond." We put on clothes and headed out. Before we left I picked up the remote and my camera and put them in a bag to take with us. "What's in the bag Uncle?" Cassie asked. "I brought the security remote so that we can stay up there for a bit" I said. Turning to Sandy I said "There's a security system that alerts me if anyone comes up the road. There's a fixed one in the cabin - we knew when you opened the gate and we could see it was you on the monitor. There's also a remote that I can bring with me when I'm out of the cabin. It helps prevent being surprised in 'compromising' situations." "I can see where that's almost a necessity." Sandy said with a big grin on her face. We spent some time at the pond, lying on the loungers fully clothed. Even though the air temperature was cool, the pond being in a hollow area was out of the wind so the conditions were quite pleasant with the sun shining on us. While Sandy and Cassie were snoozing on the loungers, I managed to snap a couple of candid photos to add to my collection. After an hour or so, we put stuff away, and I gathered up the camera and remote and we headed back to the cabin. When we got back, Sandy asked Cassie to go out to the car and get her bag. While Cassie was gone, Sandy and I went out on the porch where I quickly filled her in on what had gone on and what I was planning. "So far, we've explored masturbation including mutual masturbation. I've eaten her out and she's given me a blow-job. We've also done a sixty-nine. We've been sleeping together for the last two nights and I've woken her up by playing with her breasts. Tonight's plan is to take her virginity. I wanted you to be here for that special moment." Sandy started to cry and gave me the biggest hug I'd had for some time. "Oh what a wonderful brother you are. I'm so glad you waited so that I could be here with you." Sandy said. After wiping her eyes she continued "I guess there won't be room in your bed for me if Cassie is there." "Oh yes there is!" I replied. "The bed is one of those 'super king' sized beds and there's lots of room for three - maybe even four people. I planned that you'd be in it with Cassie and me." Sandy looked like she would cry again, but came over and gave me another big hug and a long lingering kiss. "Mom! Uncle! What are you two up to?" Cassie asked smiling. "Oh Uncle Harry was telling me about your lessons. Did you put my bag in yours and Uncle Harry's bedroom? I'm going to sleep with you as well." Cassie looked startled for a moment, then smiled and said "Neat! All three of us in one bed. Maybe Uncle can wake you up the way he wakes me up." Sandy just smiled and said "Let's go back inside." We spent the balance of the afternoon talking just like we would do if I came over to their house in Euston. After supper, Sandy took Cassie aside and went into the bedroom. I went out onto the porch and waited, knowing that Sandy was preparing Cassie mentally for her first fuck. After about half an hour I heard Sandy call me and I went back into the cabin, stripped off and went into the bedroom. Cassie lay on the bed with a happy look on her face while Sandy sat down at the foot. As I approached the bed I leaned down and whispered in Sandy's ear to go and get the camera. While Sandy was getting the camera, I went up, sat beside Cassie and started to talk to her. "My dear Cassie. I've been looking forward to this time ever since your mom first brought up the idea of teaching you about things sexual. You are a vision that only a dead man would not respond to. Tonight we're going to give one another the most precious gift a one lover can give the other." I paused for a moment. "I know that you and your mom talked about things in here earlier and I'm sure you know that there will likely be a bit of pain. My heart will go out to you, but the pain will only last for a moment and from then on you'll feel nothing but pleasure. You know that if there was any other way, I'd never hurt you." Cassie nodded. "Here's one of those 'I explain later' things that I mentioned before. In school you learned that when a man cums in a woman's pussy, she may get pregnant, but you don't have to worry about that with me. When I was much younger I had an accident and now while I still cum and have that white stuff come out, there are no sperm in it. I'm what's referred to as being 'sterile'." Cassie nodded again. "Your mom will stay here with us and will share this moment with us. Is that okay?" Cassie smiled, nodded 'Yes' and visibly relaxed. I got back up off the bed and nodded to Sandy who took a picture of Cassie laying there - waiting to be transformed into a woman. Once the picture had been taken I climbed back up on the bed beside Cassie and propping myself up on one elbow began to lightly stroke Cassie's face and neck then started kissing her. At first Cassie just lay there not knowing what she should do but as she started getting aroused she reached down and took my cock in her hand and started to stroke it. I indicated to her that she should wait and she reluctantly let go of my cock. I leaned over near her ear and whispered "Do you want your uncle's cock in your pussy?" As I was saying that I was watching Cassie's face out of the corner of my eye. Her eyes popped wide open and there was a look of shock on her face. As I continued to watch the look of shook changed to one of pleasure – lust almost. I smiled to myself and then moved lower to kiss her neck. Moving even further down, I took one of her nipples in my mouth and sucked on it, then gave a little nip. This brought out an "Oh!" from Cassie and I continued, this time with the other nipple giving it both a suck and a light bite. I moved back towards her ear again and whispered "Getting horny Cassie?" then leaned down and gave her a hickey on her neck. "Like that, Sweetie?" I whispered as I gave her another hickey this time on the other side of her neck. Cassie was laying there writhing in anticipation, panting and seemed unable to speak. I leaned back up to Cassie's mouth and started to kiss her and soon we were madly French kissing one another. I sensed that Cassie was rapidly getting ready and I moved down, kissing her belly as I worked my way down to her pussy. Having already experienced the joys of oral sex, Cassie opened her legs up in anticipation and I was soon down giving her pussy its last tongue bath as a virgin pussy. While Cassie and I had been playing with one another I could tell that Sandy had been taking pictures and I had seen the flash as she took more. I looked down deeply into Cassie's face and said to her "Are you ready?" Cassie reached up and held my face in her hands. "Oh yes Uncle! I'm so happy and I know you are the best thing that could happen to me. Go ahead, make me a woman." "Since this is your first time, I think it might be best if you were on top." I said and lay down on the bed beside Cassie. "Okay, get up and straddle me looking at my head. That way you can control how fast things happen. Okay?" Cassie got up on her knees and looked at me and smiling said "Thank you Uncle." She got up beside me and putting one leg over me straddled me. At that moment I felt a hand reach in and take hold of my cock and start to position in below Cassie's pussy. "Okay dear," I heard Sandy whisper to Cassie, "just let yourself down onto Uncle's cock. I'll make sure it goes in the right place." With that Cassie started to ease herself down onto my cock. Cassie was wet, both with the saliva from my foreplay but also from her own secretions. As she eased down, I saw just how aroused she was since I slid in to her vagina easily. Finally I felt my cock make contact with her maidenhead. "Cassie, if you keep pushing it's going to hurt. My cock is up against your hymen." I said. Sandy moved up by Cassie and quietly said in Cassie's ear. "Sweetheart, you might find it easier if you moved back up a bit then came down quickly. That way your hymen gets broken fast." Cassie's face was flushed with excitement and she nodded to indicate she understood. With that she lifted up, took one hard lunge down and forced me through her hymen. I could sense that Cassie had felt a moment's pain. I put my hands on her shoulder to stop her moving and whispered in her ear "You're now a real woman; rest a bit." Cassie paused for a moment then a look of contentment spread over Cassie's face and she smiled at me. "Thank you Uncle, oh... oh... ohhh..." I waited a bit more and said "Ready to continue?" Again a nod of 'Yes' from Cassie and she started to rise up and down, increasing the tempo as she did. I could feel Cassie responding and sensed she was near to having her first orgasm with a cock in her pussy. "AHH...! AHHHH...! AHHHHH...! Ohhhh... Ohhh... Oh YES!!" she yelled as she climaxed and with that I came as well and filled her pussy with my load of cum. "Oh Uncle! Ohh... Oh that felt so wonderful! Ohh... Ohh... Oh..." A pause. "Oh I can't wait to do this again!" I rolled her over beside me and held her tightly in my arms and as I kissed her and nibbled on her ears I began. "Cassie, you've experienced the real joy of sex between to loving people. Now you understand why this is often called 'making love'. Two people don't have to love one another the way you and I do to fuck. In that case there's no love, just some actions to give the two individuals sexual release. That's not much difference than those two dogs out in the alley behind your place in Euston - remember telling me about that?" Cassie nodded. While Cassie and I were talking, Sandy had moved up to sit on the bed beside us and took Cassie's hands in hers. "Oh honey, I'm so happy! You looked wonderful and Uncle Harry was so gentle with you. How do you feel?" Sandy asked her newly fucked daughter. "I feel different, Mom." Cassie replied. "I can't explain it different, but soooo nice! Ohh...!" Turning to her mom she reached up and gave her mom a long kiss, then broke the kiss, turned to me and did the same. Sandy smiled and reached across to give me a big kiss as well. Looking back at her daughter, she suggested that they go into the bathroom and clean up. "Look down there..." pointing to Cassie's pussy "...you're all messy. Can you see the pink mixed in with Uncle's cum – that's the blood from Uncle taking your virginity. We'll go and get you cleaned up then we'll come back here and cuddle some more." With that, the two women got up off the bed and went to clean Cassie up. I got up and changed the sheet on the bed so that we would be sleeping on clean sheets. Sandy and Cassie came back and climbed up into the bed and following their lead, went and cleaned up. When I returned I joined them in the bed. We lay there for a while, Cassie between Sandy and I, cuddling one another and talking but soon we all fell asleep.
