As I lay there savouring her sweetness she got up and went to the bathroom . she came out and walked over to the mirror looking at her large love bite and kept touching I. I walked over to her and stood behind he and cupped both her breast in my hands and squeezed her nipples and she was soon moaning and I leaned over her and started to bite and suck the other side of her neck before she stopped me and just said later. She opened the small fridge and took out a bottle of white wine and picked up 2 glasses we then both went onto the balcony and she poured us both a glass and we sat down and sipped them It was then I realised that we were both still naked but she didn't seem to mind and we talked about what had happened earlier and she said that she couldn't believe the difference between different men's pricks and their length and widths. I tried to explain that it was only the same as women's tits . She laughed as she said that we had both been left on the short side. She then told me that she was surprised when I came in her mouth as she didn't realise she was getting me so exited and it was as she was having her orgasm that she realised that my sperm was hitting the back of her throat We were sat there drinking and I heard giggling and then Abi say " Wow my big brother just had his first blow job " and we turned to see Abi and Sean sat on the next balcony. We both blushed and the girls asked which restaurant we were going to and Sean said he had heard of a great Chinese so we arranged to meet in 2 and half hours. As we finished our wine Abi and Sean disappeared inside and must have left the patio doors open as we could soon hear their bed creaking and the sound of moans of sexual pleasure . We went back inside and sat on the bed and were soon fondling each other when I was further surprised when Grace turned to me and said " Gary do you remember us watching fifty shades last year will you please spank me and then I want to try sex in another position so is there one called doggy we can do that and you can spank me at the same time." I was in total shock and could not believe what I had just heard but just grabber her wrist and pulled her across my knee and as she reached under herself she grabbed hold of my prick and balls and I was lost in the moment and I just rained the smacks down one after the other onto her pinkish bottom and also on both her thighs as she was wanking my cock. I stopped and we moved onto the bed and I told her to get onto all fours and I got behind her moved her legs apart and slowly entered her I was soon into a good rhythm and was also smacking each bottom cheek she was soon having a massive orgasm and as he screamed out I realised the bed had been banging against the bedroom wall meaning that Abi and Sean would have heard everything. We both had a shower and got dressed I was again shocked to see her getting dressed in a really short skirt and red thong and matching bra and a Black lace see through top. We had our meal and no mention was made of the bed banging against the wall but we had an early start for our boat party so agreed to an early night. As we got back to the rooms Abi just said could you move the bed a bit forward please and don't leave any bruises on Grace's bottom will you Greg." We both blushed and rushed inside. as soon as we were both inside we both burst out laughing. We both finished up going to the toilet before jumping into bed naked and were soon at it like rabbits. We soon fell asleep and our alarms went of at 07.00am and we got up and showered and got dressed in our swimwear after we had covered each other in our all day sun lotion. we then got all our stuff into our beach bag and put three bottles of water in. Once we were dry we got dressed and Grace was wearing a yellow bikini which only covered where it touched and she had put a spare red thong bikini into our bag. We knocked on Abi and Sean's room and they were just coming out so we made our way down to the port and were met by the reps who told us there was free food and all games drinks were free. As we made our way onto the top deck we managed to get a table and put or bag down and the boys both had a waterproof pouch in their shorts to keep our money in along with our hotel key cards. We were told that there was a fruit and salad bar downstairs if we wanted to go downstairs so the girls both went down and came back with a tray each and piled with fruit and salad and a glass of orange each. We had our fruit and salad as we had not had breakfast. within 30mins the boat had stopped and the reps were asking for girls to come forward for the first game Wet T shirt well Grace immediately shook her head due to her small tits but the rep gave her the first of may shots which she was told to knock back in one she did so and was about to sit down when she was told that by downing the drink she had agreed to take part . So she took her sarong off and was give a very thin white t Shirt which she had trouble putting on as it was so small. There were son about 20 girls stood in bikinis with these t shirts on and some were obviously bigger that others Abi and grace were about three girls apart. The girls then had to remove their bikini tops and one at a time were called up onto a small stage and the reps would turn a hosepipe ont0 their backs at first before finally turning it onto their front. Almost immediately the nipples hardened and the girl was encouraged to writhe around sexily as the crowd cheered. the reps the took hold of the front of the T shirt and just used a pair of scissors and cut through the hem at the neck and started to rip the t shirt off and the girls had to dance as sexily as they could Abi was next up and her nipples really stuck out when her shirt was ripped off she was as good as most of the others. It was soon Grace's turn and was I in for a shock as she took the scissors of the rep immediately and cut the top herself as soon as her nipples and shape of her boobs were visible through the shirt she ripped it open and played with her nipples and tits even bending over and shaking her tits at some of the men before playing with her nipples again before sliding her hand down the front of her bottoms and her hand obviously went between her legs playing with her self. The crown were baying for more and at the end she was a clear winner. and won 2 tickets to a night club. There were plenty of games and at the end after we had eaten and swam a bit and had a great time the boat started to head back . The last game was called and all the winners were to take part in it Each girl was teamed up with a boy the game was that both would be blindfolded and they would have pieces of fruit hidden on their bodies and they would have to lie down while the boy or girl had to find them by only using their mouth all the girls had to lie on the deck and the reps put the grapes strawberries cherries cream and a slice of lemon placed over the vagina with a cherry just inside the lips. the girls then all had their hands and legs secured. when all 10 girls were secure one boy at a time was led in blindfolded with their hands tied behind their backs. A lad who won the sex position game was led in and told to lie down next to Grace the whistle went and they started the lad wit grace was soon sucking the strawberry and cream for he belly button and the his teeth fond to string to the top of her bikini and pulled it down to show a large dollop of cream on each nipple and a red cherry on top he soon was sucking on Grace's nipple and they were soon rock solid then he was told to find her mouth and he used his tongue to lift 2 grapes from her mouth the reps pulled her bikini bottoms down and said he had to find the honey pot he was soon licking all down her belly and she was writhing as he reached her pubic area and he found the slice of melon and soon had eaten it before being told that there were only 2 cherries to find so he got to work with his tongue and was soon licking her clit before moving to her slit and he found one cherry he tried to push his tongue inside but was told it was not there so his head went between her legs and he found it coated in cream in the crack of her bum.. there was a big cheer as they finished as nobody else had even reached the melon. By the time the res had finished we were approaching the town so the girls never had to perform Grace and the boy the got released and they hugged each other as they were given 2 more tickets for the club. We stopped on the beach were there was a shower so that Grace could just have a quick shower and Abi and Sean said the would see us about 8.30 pm. grace and I started to walk through the town towards our apartment and we came to and Adult shop Grace said " Grant I have often wondered what these shops are like "and pulled me through the door . I looked around and could see the shock on Grace's face we arrived with a display case of vibrators and the Spanish woman took a 7" thick one out of the display case and handed to grace and turned it on and guided it between Grace's legs and she was obviously taken aback and gave it back immediately as we were walking towards the door I nooded that we would have it so she wrapped it up and handed it to Grace as I paid and grace put it into our beach bag as the shop keepe threw a spare pack of batteries. All they way back Grace kept saying what have I done. More to follow
