The sheets were partly splayed across my body as I awoke to the gentle burble of bodies trying to quietly enter the pool outside. My left leg was covered, and a couple of pillows were around my head. One was under my head, the other at an angle similar to the rest of the bedding.

Holy shit!

Did that really happen last night?

My mind turned over as I lay there under the white bedding with the cool air caressing the uncovered skin of my body.

Had I really fucked Mabel?

Was I right in thinking that her friend Jennifer had watched us?

Did Jennifer really want to watch?

I was fairly sure Jennifer had jumped on top of my cock when I had reached the point of no return with Mabel.

I think Jennifer took the biggest load of cum I had ever produced, then quietly got dressed and walked out without saying a word.

Holy shit!

As I rolled over to check the time, it all dawned upon me as I slowly woke up and life became more coherent.

It was true.

There was an eighteen-year-old shy, quiet, devoted Christian girl in the house carrying more of my sperm than I had ever created in a single ejaculation.

I had been inside her for no more than thirty seconds. In that time I had pumped more cum inside her than I thought possible.

Holy shit!

I had just fucked my best friend’s little sister. My best mate from our earliest schooling memories and her nerdy churchie friend had jumped me and taken the load I had pent up watching the little sister’s gorgeous body bounce on my cock, her lips wrap around my shaft, the way her pussy and ass had tasted, the way she had struggled to keep quiet when she’d climaxed on my tongue, then my dick all while her brother and parents slept in the very same house.

Holy shit, Mabel was hot--her body was out of this world, but her quiet confidence was also sexually charging. She carried herself with the maturity of a much older soul. No wonder Jennifer had founded such a strong friendship with her. Mabel brought her the confidence and self-assurance she needed.

Thinking about the events last night had already given me an erection, and I hadn’t even gotten out of bed yet. I feared there was going to be a family breakfast, and I would have to try and act naturally. The worst thing I could do to look natural was to try and act it. I was a devastatingly bad actor.

I had one arm under my head and the other hanging off the side of the bed as I enjoyed the mental video of the events of the evening prior.

I slid the hand that was off the bed under the covers and grasped my cock and gave it a few strokes. I could literally jerk off right now thinking about the actions of last night, but alas, I was, after all, a guest in a house, and I really shouldn’t be found wanking in the guest bed as thirty something years old. Besides, I could smell bacon cooking.

I told myself to take it easy.

The splashing noises continued outside in the pool. It was a cool morning--I could tell because my exposed skin was being refreshed each time a draft danced over it.

I let my cock settle back into an acceptable state before rousing out of bed and putting a towel around my waist as I searched for something appropriate to wear.

I found my boxer shorts I had packed yesterday to wear to bed before we’d decided to have a few drinks, and I’d made a couple of more liberated decisions.

I slung them on, made up the bed as best I could, and headed out of the guest room, up the hallway to the main bathroom.

As I made my way, I glanced out over my right shoulder towards the pool, curious as to who was in there. I’d figured it would be Tom, eager to sort out what had to be a decent hangover after his efforts the night before with a dip in the water to ease his throbbing head.

Nope.

It was Mabel and Jennifer. They were both sitting in the shallow end, deep in conversation. As there was no one else watching, I took in a good view of them both. Mabel in a black bikini, looking vivacious as her bikini top curved perfectly around her bust, encasing her cleavage in a frame that would make any art gallery proud. Funny how the simple things in life are often the best. A plain black bikini on an incredibly well-shaped body, garnished with flowing red locks of wavy hair, sat in the shallow water on an angle that only accentuated her curves.

Her hair was wet; she had obviously been under the water, and she had her hair pulled back over her head.

Jennifer was also in her swimwear. However, hers was a much more conservative one piece, predominantly white, with thick blue stripes running one way and fine lavender color stripes in the opposite direction. Her hair was also wet, but it appeared she had been under the water most recently.

Jennifer’s hair was long. When it was wet, it reached midway down her back. It was blonde, and it fell into a similar wave to Mabel’s. Her lips were full--not in a manner that suggested fillers, more like an innocent, country homestead fashion. She had white, perfect teeth and a lovely smile on the rare occasions one was offered. Her body was lean. Not unhealthy, but lean. Her figure matched this with a minimal bust but a well-defined figure that would look fantastic in a figure-hugging evening dress or activewear. Her legs looked toned, along with her ass, which was proud and firm.

If you didn’t know her, you could assume that she was arrogant or stuck up.

Mabel saw me gazing out towards the pool. She waved and shot me a full smile. A smile that included her eyes. The sort of smile that came from the heart--not a superficial ‘tick the box’ smile. Her confidence allowed her to be engaging and wholesome even in what could have been an awkward position.

I smiled back.

Jennifer looked up at me then looked straight back down at the bottom of the pool, or her feet--anything but me.

I felt sorry for her. She’d been curious last night and had followed through on her lusty inclinations to now be fraught with self-doubt and feelings of guilt. Her family would not be at all happy if they knew what happened. She was probably preparing for confession or something similar; the church they went to was one that did that sort of thing.

She wasn’t arrogant or stuck up. She was reserved, shy, and seemed to be a little bit stuck inside herself. Her family had seemingly liked that she was conservative--after all, it seemed to fit their ideal for a young lady. The best thing for her, in my opinion, was to bounce off the confidence and maturity that Mabel brought her.

I continued up the hall and through the kitchen. Tom and Mabel’s parents were cooking breakfast for us all. Bacon, eggs, hashbrown, and coffee are all combined to create an air of breakfast in a summer house next to a lake somewhere beautiful.

“Good morning!” I began. Hoping to sound confident. It worked.

“Good morning, how are you today?” their mother replied.

“Good morning, boy. How are the parents going?” Their father had asked a second question before I could answer the first.

“Thankyou. I’m going well. Yep, the parents are really happy. Their new place is so good for them now.” I was hoping to answer both questions at once.

I’d nearly forgotten the real reason I was there at all. To help my parents move to their new, smaller place.

“That’s fantastic. Make sure you say hello to them for us. We haven’t seen much of each other since you boys finished school.” Their mother took over the topic while the dad continued beavering away in the kitchen.

“Oh, I’ll definitely do that; they feel exactly the same. Thanks again for letting me stay. It was a bit like old times.” Almost all of that was true, I thought to myself after I’d finished saying it.

“We’re going to have to get moving before we eat, unfortunately. Breakfast will be ready in about ten minutes. We have to get over to the mechanic first thing this morning to drop off our car. We’re supposed to be at golf in an hour.

No worries. Thanks for cooking for us. I’ll go and check in on Tom.

As I headed through the kitchen, the girls came in through the back door, probably attracted by the same smell that got my attention. They were each wrapped in a towel. I took my opportunity to not pay them any attention considering the parents were in the room. I continued up and gently wrapped on Tom’s door.

No answer. I opened the door slowly and peered in. The room was dark, and he was still fast asleep. I stood at his door and considered my next move. I didn’t really want to go back to the kitchen and talk with the parents and the daughter I’d just fucked and her friend while I’d been staying at my friend’s place.

No, I decided a better idea was to have a shower before I headed back for breakfast.

I entered Tom’s room and made my way to their bathroom. It’s one of those 90’s bathrooms designed to cater for two bedrooms and also act as a family bathroom. The architectural idea is that it services three rooms, but in practice they’re a nightmare. Every time you need privacy, you need to lock several doors.

I heard the front door close--their parents were on their way. I’d made the right decision.

I went in the bathroom and went through the process of locking the doors before sliding off my boxers and jumping in a hot shower. The warm water cascaded over me, taking away the chill from the morning air and giving me another opportunity to go over the events of last night--this time with cock in hand. I felt surprisingly recharged as I stroked myself.

My cock grew quickly, and the veins always pop as I near my full seven inches. The best part about my cock, so I’m told, is the girth. It’s thick. My helmet head is proud and is matched by several pronounced veins that run the full length at random angles down the shaft.

As the water rolled off my back, I closed my eyes and stroked slowly. Savouring how it felt when Jennifer sat on my cock and we watched it slowly, decent to her depths.

I considered how ironic it was that I’d fucked Mabel but not cum in or on her, yet I’d blown a monster load inside Jennifer, yet I’d only been inside her for about thirty seconds.

I caught myself again, remembering that I was in a shared bathroom, so I turned off the shower and got out and grabbed a towel to wrap around myself. I looped the towel around my waist and pulled my hard cock up against myself while I busied myself with hair and teeth and the like.

I heard a rustling behind me, then another door closing. Someone was in Mabel’s bedroom. I continued sorting myself out when there was another sound. This one made my heart jump--someone was trying to open the door to the bathroom.

Sure that I’d locked it, I wasn’t too worried.

There was another attempt to open the door, and this time it unlocked and swung open.

Jennifer was drying her hair as she walked in, unaware that I was already in there. Her eyes were down as she worked her towel through the hair on the top of her head.

I felt so exposed as I stood there in a towel with a raging boner against myself brushing my teeth.

“Oh sh*t, sorry Jennifer!” I gasped as she walked in.

She jumped back, and her eyes shot open as she reacted to my voice.

Looking up at me, she went instantly red as she blushed. The embarrassment of walking in on me was already obvious.

“Oh, oh. I’m sorry,” she spluttered as she looked up at me, then straight back to the ground.

“Ha ha, it’s ok, Jennifer. Don’t worry about it.” I was trying to console her. Fuck, accidents happened.

Surprisingly, she didn’t leave immediately.

She continued, “No, I mean, I’m sorry about everything.”

My interest was piqued. “What do you mean?”

“Last night. I shouldn’t have been in the room, and ... I shouldn’t have...” She paused.

“Shouldn’t you have what, Jennifer?” I was teasing her now.

“You know”

“Can I tell you something?” I was starting to get the feeling she was trapped inside herself again.

“Sure”

“I don’t think you give yourself enough credit for the person you are. You’re smart, highly attractive, and I love your smile. We just don’t see it very much.”

She smiled. “I’m not as hot as Mabel--she’s got everything,” she joked.

“She’s attractive for sure, but the hottest thing about her is her confidence. She’s the best thing for you, and you’re the best thing for her as well. You two complement each other.”

For the first time, she looked up and looked me in the eyes. She looked a touch more relaxed. Her gaze went down to my towel and its obvious bulge.

“Is everything ok down there?” the enquired.

“No,” I replied. “I was thinking about you and Mabel last night when I was in the shower. That was fantastic. Fuck you were hot.”

“You made me cum.” Jennifer was looking straight at me now.

“Oh fuck Jennifer, you made me cum as well.”

“Those thirty seconds you were naked and on top of me--fuck that was sexy. Then you get up, get dressed, and leave!”

“It felt so good, then I felt so guilty.”

“That’s ok, if it’s what you believe, but I hope you only feel accountable to you and do what you want, not what others want.”

I continued

“I wanted to make you feel the same as Mabel last night--give you the same attention. Fuck knows you deserve it.”

“You were my first real cock.” Jennifer blurted. “I mean, I’ve had other stuff but not a real cock before. It felt so good!”

I felt my cock move again.

“Can you please close the bedroom door? I want to let you feel things you haven’t before.”

“What about everyone else?” She was nervous.

“Tom is asleep; Mabel is having breakfast; their parents have left already.”

Jennifer moved quietly to the door leading to Mabel’s bedroom and closed it.

My cock continued to harden.

I took her by the hand and led her to the vanity.

I whispered in her ear, “There’s so many parts of you I wanted to kiss last night.”

I reached for the top of her towel and grasped where she had tightened it around her chest.

I continued, “Almost all of those parts are under this towel.”

I gently tugged the towel knot and took each side of it in my hands before it fell on the ground. Holding my hands together so she was still entirely covered by the towel, I slowly separated my arms to expose her body. As I slowly lowered the towel behind her, I moved in and kissed her on the neck as I lowered my hands by sliding them down her back, then ass, then legs until I placed the towel on the ground.

She stood in front of me in her swimwear with me in front of her with my hands on the ground behind her. As I moved to stand back up, I kissed her bare legs, then her covered stomach, sternum, and back to her neck.

I could feel her breath shortening as I caressed her body. I’d deliberately kept my hands as low as possible behind her as I came up; now I slowly slid them back up, over her ass, around her waist, up her sides, and over her bust.

I pressed my engorged cock onto her as I whispered, “I came in you last night; I want you to come this morning.” This caused her to slightly whimper as I picked her up and sat her on the vanity.

The way the bathroom was setup, there were mirrors on both sides of the room--one in front of the vanity and another on the opposite wall, between the doors.

As she sat on the vanity, with her towel on the ground in front of her, I wanted her to enjoy what was happening.

“I’m going to put my tongue inside you. I want you to celebrate your body by looking in the mirror in front of you, and I want you to enjoy me because I will be celebrating your body from down here.” I gently touched her pussycat through her swimwear.

She replied by grabbing my cock and exhaling fully. I took her hand and held it as I whispered, “Hopefully we’ll get there, but just enjoy this for now.”

I kneeled between her legs. I looked up at her and asked her if anyone had ever done this for her before.

“No”

I started by sliding my hands from her ankles up her calves, over her knees and up past her waist, and on to her bust, then up and over her shoulders before back down over her bust, and back to where I started.

Putting my hands on her knees, I gently separated them before kissing her pussycat through her swimsuit material.

I’d remembered that she was already shaven, so this made the idea even sexier for me.

Using one finger, I slowly slid her swimsuit crotch to one side, exposing her perfectly shaven pussycat.

Kissing her calf, then thigh, I worked my way to her pussy, pausing just before it as I looked up to her.

“Are you ready?” I asked.

“YES!” came her reply.

I started by just touching her pussy lips with the tip of my tongue. I barely made contact the first three or so strokes. Then I sat my tongue on her pussy and left it in place as I applied a little more pressure with a side-to-side motion to work open her lips.

She moaned.

As my pressure increased, I moved gently up, finding her clitter for a couple of slow passes over it as well before inching back down.

Because I had just had a shower, I was able to gather a lot of saliva, which I rolled off my tongue onto her eager pussy, making it easier for me to get deeper without any extra pressure and also easier to find her clit as it continued to swell.

I looked up at her.

“Make sure you look at me and make sure you look at you.”

I slid my hands up her body and let them settle on her tits. They were probably an A cup, perhaps a B, but I could feel her nipples through the material. They were firm and proud.
