Lexi had been as good as she had promised, she sucked me off every day until the night before her 16th birthday. Mum, Mandy, Sue and a few others seemed to spend most of their time together, sometimes at our house, but much of the time they went to a local garden centre for coffee and cakes, leaving me to get on with whatever I wanted to do. I had decided to stop working, I did not need the money, and it was boring me.

Mum told us a few days before Lexi's birthday that she had invited Mandy to organise Lexi's part at our house. This sounded good to me, it would give me a chance to see their friend's in their bikinis again. It was a prospect that I was looking forward too, and it would mean that Lexi would be at the house, giving me the chance to fulfil my part of the agreement.

Ever since Kelly had moved out, I had been sleeping with Mum most nights Sun -Thurs, (I liked to keep fri and Sat to be with Candi or Katie). For the 1st few nights it was just sleeping, but after Mum had spent a few lunches with the WI, that she seemed to regain her sex drive.

The day of thr party eventually came. Mandy, Leo and Lexi arrived the hose at about 10.00, it was a Saturday. I had only just woken when they got to the house, and was in the shower when I heard my bedroom door open, I presumed it was Mum. (After Kelly and Ellie and all the twins had moved out,  Mum had suggested that Candi and Katie moved into their old rooms, so now they were in the bedrooms opposite mine, the adjoining room next to me was now empty).

I rinsed the soap out of my eyes and saw Lexi standing outside my shower, she was rubbing her boobs through her top with one hand, the other was in her panties. She was staring at me, then said, I dont think I will be able to get all of that into me, she was looking at my hard cock. I told her I would give her as much of it as she could take, but later. I got out of the shower and she offerred to dry my back for me, but it was not long until she was drying my cock.

I got dressed, and told her to go down to the others, saying I would be down in a few minutes. When she had left, I was tempted to have a wank, but thought it would be better to keep my cum to fill her later. I went down a few minutes later and joined them all in the kitchen.

We had coffee and Mum cooked us all breakfast. Mandy was looking really good today, her hair was tied back, and she was wearing a figure hugging dress. She had make up on, and looked better than I had ever seen her look before. Mum told me that it was all due to start at about 1.00pm.

At about 12.00 everything was ready, Candi, Katie and Lexi went to put on their bikinis, it was then that Lexi discovered that she had forgotten to bring hers, and there was no way that she could borrow one from Katie. I told her I would take her back to get one, Mandy thanked me for offering, as she'd had a few glasses of wine, and could not drive, so Lexi and I went out to my car and headed off to collect her bikini, getting to their house about 15 minutes later.

When we got to her house, she asked me to go in with her. We went in and she went to her room. I waited in the kitchen. A few minutes later she called and asked me to help her. I went upstairs. Lexi was standing at the door of her room wearing just her bra and panties. She told me she wanted me to help her decide what bikini to wear, then went into her room, I followed her in. She had a few bikini's lying on her bed, she asked me which one I preferred. I told her it would be easier for me to chose if I could see her wearing them, and I started to leave the room while she got changed, but she told me to sit on her bed.

Lexi stripped off her underwear, she was then standing in front of me totally nake, by now my cock was getting really hard, she saw this and came over to me saying it would be better if I was naked too. When she had me naked, she pushed me back on the bed and told me she was really wet, and she thought it was time for me to fuck her, as I had promised to.

Lexi knelt between my legs and started to suck my cock while she rubbed her pussy. She told me she thought she was wet enough now, and stopped sucking me. She moved forward until her pussy was over my cock, then she started to rub her pussy lips with my cock, before she tried to sit down on it. My cock managed to get about 2" into her before she told me it was too painful. I told her to get off and she lay down on the bed. I got between her lags and started to lick her pussy, then tried to slide my cock into her tight pussy. I managed to get about 2" into her before she started to cry out in pain, nut she told me to continue. I started to slide in and out of her, and finally managed to get more of my cock into her, there was some resistance than my 8" managed to slide into her. It felt great, and after a few thrusts filled her pussy with my cum. We lay on her bed for about 10 mins, just calming down, then we realised that we had to get back to the party.

Lexi asked which bikini I preferred, but I told her she would great in or out of anything. She picked a black satin bikini, and we went back to the house to rejoin the others.

By the time we got there, all of her friends were there and in the pool, Lexi went to get changed then went to join them all. Mum was in the kitchen and suggested that I go and change, and join the Adults in the spa pool. I was reluctant but agreed. I went to my room and had a shower, I wanted to get the cum and blood off me, then put on my swimming shorts and went to joun them.

When I got down, in the spa pool was Mum, Candi, Leo and Mandy, all sitting there drinking Champagne. Mum gave me a glass as I got into it between Mandi and Leo. Mandy asked why we had been so long, I told her that Lexi could not decide what bikini to wear, she told me that did not surprise her. We had a few glasses of Champagne, the Mum said it was time to eat, so we all went to the kitchen for some food.

It had been good to see all the girls in their bikinis, they had got me hard just seeing them. After we'd had our food, it was back into the spa. This time I was between Mum and Mandi, Leo and Candi were oposite us.  I was looking at Katie and Lexi and my cock had started to get hard, Mandy saw it harden and reached under the water to feel it. When I felt her fingers touch me, I was hard in seconds, and I could see her nipples as they hardened too.

At about 7.00pm, we all got out of the spa and pool and went to the lounge, as it was getting chilly. By 10.00 all of her friends had left just leaving the 7 of us. Mum suggested that Mandy and her kids stayed the night, she agreed, so we all had a real drink, even although Katie and Lexi were too young to drink. Mum suggested that Mandy share with Lexi, (Lexi said she would rather share with the girls), so Lexi & Candi shared with Katie and Leo had the room next to me. This sounded good to all of us, and after a few more drinks we all went to bed.

About 30 mins later, I heard my door open, it was Mandy.....
