As we left the shop grace said she was scared the vibrator was going to be too big so i told her to wait and returned to the shop and bough a smaller one but bigger than my cock and also some lube. As soon as we got back i went to the balcony and could hear the unmistakable sound of my sister Abbey and Sean in the throngs of sex and I returned to our bedroom too hear a bed banging on the wall on the other side of us. Grace was just coming out of the bedroom and had the vibrators in a towel and looked as though she was wanking them off but was just drying them after cleaning them both. She laughed as the bed banging continued and i was playing with the small vibrator around her clit before gradually parting her lips and slowly pushing it into her eager vagina as soon as it was in I turned it on gradually and as I could feel the vibrations increase she started to buck and work to the rhythm I was ramming the vibrator in and out after about 5 mins she was having a massive orgasm and I slowly removed it and put some lube onto the larger one it took about six attempts before I managed to get the tip into her but was soon slowly sliding it in and out as I massaged her clit and as she started another orgasm I pushed the vibrator right into her and turned it onto full power she screamed in pain but was soon moving to the rhythm I was ramming the vibrator in at. after orgasm after orgasm I slowly removed it and rammed my rock hard cock into her gaping hole and realised how stretched she was but i didn't care as i immediately filled her with my spunk. l lay there as she went to the bathroom as my spunk was just running down her thighs. i was worried then that by introducing her to the large vibrator she would need someone bigger than me to satisfy her in future. i picked up a bottle of beer and went to sit on the balcony. Abi was sat there with a glass of wine we were chatting for a while and agreed that we would have a quiet night in the hotel and there appeared to be some sort of party night in the hotel next door. The couple on the next door balcony were. stood looking over the balcony and as the girl turned she smiled at us before she disappeared inside . Abi looked at me and whispered she is very young there is no way she is over 16. I told her that the bed had really been banging against the wall and she told me that she had heard them talking before I had come out and she thought it had been her first time. I said that the bloke was at least 20 as we had seen him and his room mate around the pool. Grace joined us on the balcony and we sat there drinking and soaking up the sun for about an hour or so. Sean came out and asked if we fancied going to the isolated beach again tomorrow with it being Sunday and we both agreed immediately. It was about 7.30 we went inside and got ready to go for an Indian meal before going to the hotel party in the next hotel which was the sister one to ours but catered more or families than young people. It was about 10.00pm when we got back to our hotel and went next door There was plenty of live music and the reps were also performing and were really good we had found an empty table near to the front but were mainly surrounded by families . Sean was at next to me and with Abi next to him and his hand was virtually up her skirt the entire time when the bloke sat behind him taped him on the shoulder and I thought it was going to blow up when Sean jumped up and swung around only to be shocked to see one of his ex work colleagues and his family of wife and young son and they were then chatting all the time before his wife leaned across and pointed out that it was 10 .45 and Emma and Rose were not here yet. It turned out that Emma his daughter and her friend Rose both 15 had gone to a junior night at the club down the road and had been told to be back for 10.30 as the disco finished at 10.00 Just as they were getting up to go and look for them they saw them coming towards them. Simon then introduced the them to us and said that it was Emma's 16th Birthday on Wednesday and invited us to join them for a meal, we had a great night before bidding them all goodnight around 1,00pm on the way back to the room Abi asked Grace if she had recognised Emma and she said sje did and with the look on Emma's face she definitely recognised her we all smiled as Sean said well she has already had her early birthday present. We all laughed . As we got to the bedroom grace just threw her clothes onto the bed and pulled me onto her. We were soon at it and I grabbed the small vibrator and put some lube on it as i had what I hoped would be a surprise for her in mind we were soon banging away and I was rubbing her clit as we fucked and she starting having an orgasm and her muscles grabbed my cock really tightly she was soaking wet and her juices were flowing and i rubbed them onto he bum hole a few times before gently inserting the vibrator slowly into her bum she squirmed a bit and said it was a little sore but i was soon turning the vibrator to full power and moving it in and out with no trouble I then suggested doggy style and as she got on all fours i gave her bottom a few really hard smack and she cried for more as I knelt behind her I fed my rock hard cock to wards her bum hole and gently pushed in a few times I added some lube to my cock and was soon up to my ball in her arse and and she screamed in pleasure it was not long before i filled her bum hole up with a full load of my hot spunk. After we had both been to the bathroom to clean up we fell asleep naked on top of the bed clothes . i was awoken about 4.00am to funny noises and found Grace vomiting over the toilet and she told me sh had had the runs as well she hardly moved till 7.00,am when I heard somebody on the balcony next door and went out to find Abi having a glass of water i explained how Grace was and that we would not be able to go to the beach but that they should still go. At about 0830 there was a knock on the door I opened it expecting the maid but it was Sean and Abi so they came in and Grace who had just dozed off but was fast asleep naked on top of the bed . So they left and said they would call to see how she was on their return. I lay down on the bed and was also soon sleeping .I woke up at about 10.00 and opened a bottle of water before waking Grace to make sure she had plenty to drink she soon ran into the toilet before returning after 15 mins cursing me and blaming me for fucking her arse for her being in the condition she was. i said that fucking her arse would not make her sick as well . I told her i would go and get some fruit for her. She managed to keep a banana down and slowly started to improve . we put our once a day all over sun creme on and eventually about 2.30pm managed to go down to the pool with Grace drinking several small bottles of water. she was wearing her red thong bikini and when she removed the top and turned over she pull the thong so that it went right between her bottom cheeks so that she was for all intense and purposes naked to look at. The next bit is told by Grace as I took ill and had to rush to the bedroom and she then followed me a few mins later. I arrived at our room and Greg was sat around the toilet vomiting continually before asking me to leave the room and as I did so there was no mistaking why as the smell and sounds were disgusting as I made my way to the balcony I noticed in the mirror that my love bites had virtually gone and that I had a very nice tan I lowered my bikini bottoms and took the top of to see that apart from a very thin patch either side of my slit I had a completely all over tan and was very pleased.Greg stumbled out of the bathroom and gave him some water before saying that I would go and find a chemist to get some Imodium . I arrived back about 5.00pm as I saw Abi and Sean struggling to get out of a taxi I rushed to join them to be shocked to find that they were both very badly sunburned. I told them to go upstairs and I would go back to the chemist. I made it just before they shut and told them how bad my friends were and she gave me a large jar of Aloe Vera Gel and told me to smother them both in it and leave it for twenty minutes to cool their skin before massaging it in then repeating the action again. She added that I had better take two jars to make sure I had enough. I returned to the hotel went to see how Greg was and gave him the and put the 3 bottles of water into the fridge Imodium before going next door to Abi and Sean they were both stood arms out legs apart stood naked as the air con blew cold air over them. They both turned and their rears did not look too bad but when they turned to face me I was shocked as Abi around her boobs and especially her nipples looked to have been really badly burned also her upper thighs and around her vagina was the same Sean's nipples were againnvery painful but his penis and scrotum and his upper front and inner thighs were really badly burned . I suggested it might be better to go to see the doctor down the road but they both refused . They explained to me that they had been swimming in the sea but that the caravan was closed as it was a religious festival day as well as a Sunday and They had took a sun cream that was empty and had then fallen asleep on their backs for 2 hours. I told them what the chemist had said so Abi lay down on the bed and I applied a liberal amount of the gel it was strange applying it over her vagina. Then Sean lay down and I did the same to him but it meant me touching his penis and scrotum and I was really embarrassed as apart from Greg I had never touched another mans penis before. I left them lying there and went to buy some more water left 4 bottles with them and took the other 18 to our room. I told Greg how bad they were and what I had done and he laughed as he asked if Sean had got hard when I coated his prick in gel I blushed and said he must have been in too much pain. I returned in time to start to massaging the gel in again i was embarressed as I massed Abi tits and nipples then her vagina then did the same to Sean . As i returned to massage the gel a second time I was not as bad but as I massged greg he did start to get hard and I was shocked that my hand would not meet around his prick and I was just in a trance till I realised I was actually masturbating him and he soon shot 4 loads of spunk in my face my hair on my bikini top and I rushed out and into our room and Greg saw me and just started to laugh as I realised some of his punk had dripped into my mouth More to follow
