Lin and I had had a great sexy evening helping to cheer Nickki up and I think she felt that she needed to return the favour at some point. A couple of months after our night of fun in, Lin, always up for a new experience, suggested we invite Nicki round for a summer BBQ with her new partner, Mark. Early summer and the heat was building up and warm dresses and shorts were the order of the day. We prepared a variety delicious food for the BBQ accompanied by a generous supply of drink to help get the atmosphere light and right. Nickki and and her new beau arrived in good time. Nickki looked so much happier and what is more stunning in a pair of very tight black jeans which fitted perfectly over her beautifully rounded bum, complemented by a contrasting low cut pure white T shirt hiding a red bra holding up her awesome breasts. Mark was a lucky man having this lovely perfectly proportioned mature lady on his arm. Mark, a good ten years younger than the rest of us, was a well dressed toy boy in a white linen shirt and well fitted pair of navy shorts. Nickki took no time in proudly introducing her young man to us. A could tell that Lin liked the look of the young lean machine that was Mark and I started to get the idea that this could be an interesting evening in more than one way so to speak. The drinks started to flow and with that the four of us relaxed. Lin herself looked lovely in her mid length summer dress buttoned at the front, the top ones undone which when Lin bent over gave a good view of her gorgeous tits to the party. This was all she had on. Underneath there were no knickers or bra as I had requested that. The thought of Lin chatting away to Mark and Nickki hiding her secret of no underwear certainly turned me on. Now and again I was able to steal a quick feel of her bare bum under her dress when nobody was looking. But there were chef's duties to attend at the BBQ. Within a hour we had all eaten our fill outside in the garden around the patio table. The well chilled Prosecco had worked well in helping us all relax and settle inhibitions down and enjoy the evening. Lin and I cleared everything away and whilst in the kitchen alone I gave Lin a deep and loving kiss. Lin opened her mouth and our tongues touched and explored. I felt down her body and lifted her dress in order to get a good feel of her bare bum and allowing my hand to come around to her fanny and her legs automatically parted. I could tell that Lin was getting excited and my hand was getting damp. We could not be too long away from Nikki and Mark. We should not have worried. As we walked back outside Mark was bent over the seated Nikki and giving her a long deep passionate kiss. Nikki in return was feeling the goods in Marks pants! Nothing was holding them back it would seem. I gave out a loud wolf whistle and they both looked up and laughed. "Don't mind us" Linda said in an encouraging tone " Relax and enjoy the evening" she said provocatively. "We have been warming up indoors" she continued. In saying that Lin turned to me and gave me a full on kiss. "Just like that." Nickki and Mark were not at all embarrassed and got back to the job in hand. Mark kissed Nickki again and at the same time started to feel her more than ample boobs. Nickki was thoroughly enjoying the attention. We were enjoying the view too. I gave Lin another hug and at the same time I lifted her dress up exposing her lovely arse. Things were developing quickly. Mark could not believe his eyes which were fixed on Lin's pert bum. Nickki was excited too.

"Is the Hot Tub warm enough for a dip" Nickki asked in a hopeful tone. Located in the other corner of the garden the Hot Tub looked inviting.

"It is indeed" I replied in phoney innocence. I knew what I had in the plan and hopefully they did. Perhaps they are mind readers I thought.

"Shall we?" asked Nikki.

"I think we should" replied Lin lifting and slipping out of her dress as she spoke.

"Come on Mark get your kit off and show them what you have got in there!" Nickki cheekily suggested. Without needing any further encouragement Lin with nothing left to take off ran over to the Hot Tub and with one swing of her leg she was in the water. I quickly followed not before shedding my clothes. My cock was already anticipating some all round full on foursome fun.

“Come on get em off you two” Lin joked.

I watched intently as Nikki lifted her arms up and Mark pulled her t shirt off over her head. Quickly Nickki unclipped her lacy red bra and her stunning breasts for all to admire. Mark was out of his clothes. Nickki hand in hand with Mark rushed over to join us. Nickki lent over and tested the temperature. Nobody was going to get cold! As she bent over the hot tub Mark slipped off Nickki’s black thong. What a lovely mature body. One that needed a real good sorting I thought to myself

All in the water. Linda and I started snogging and feeling each other all over. The sight of the impromptu strip had excited us both. Lin has a strong bi side and here was a full on chance to explore together. I could not help noticing the size of Mark’s cock as he got into the hot tub. It was now looking ready for some action. Linda had been working on my cock under the cover of the bubbling hot water.

“ I will go and replenish the drinks” I suggested. “Mark can you look after the girls” I added

“No! We will both look after Mark” responded Linda.

I struggled out of the hot tub and went inside for another bottle of bubbles and cups. When I came out Linda had been true to her word. Mark was sitting between the two ladies and they both had their small hands around Marks now huge cock. What a size it was. Mark had a grin across his face.

“We must be in heaven” Mark laughed.

“Is that ok for you Mark?” enquired Nickki.

“Is the Pope Catholic?” his instant reply.

“Mark loves to be wanked” Nickki informed us.

“Make that both of us” I added “I need some of that too”

"What Mark's cock?" asked Lin excitedly

"Help yourself I don't mind who does the honours" Mark blurted out in a suggestive way. Maybe later I thought.

Nickki immediately let Lin focus on Mark’s cock while she came across the tub and got hold of my now pulsing cock and with both hands worked her magic. It was so damn sexy to see Linda attending to Mark’s needs and desires. Mark's rock hard cock was in and out of Lin's mouth.

“Go for it Lin” encouraged Nickki. “Give it to him”

Nickki bent her head towards my dick and I lifted the lower half of my body out of the water and Nickki took my cock into her warm mouth whilst looking over at Mark. You could tell he liked what he saw. I liked what I felt. I had one hand feeling all around Nickki’s big tits by now.

We all came up for air and a few sips of Prosecco. The girls lay back side by side and enjoyed the warm water and alcohol engulfing them, Lin lent across to Nickki and gave her a deep passionate kiss. Mark and I cheered on in support of this little show. Lin slipped down and knelt between Nickki's legs and continued to kiss her moving slowly down to her full breasts and further down until she reached Nickk's beautiful pussy. Lin needed no further encouragement although Nickki ensured that Lin did not back off by holding on to the back of Lin's head and guiding it towards her open pussy. Lin's tongue went straight in and Nickki quivered in response and let out a deep appreciative moan.

"What are you two waiting for and staring at?" queried Nickki "Where is the little show for us girls from the men?"

I moved tentatively next to Mark and held his cock with my right hand, felt the hardness and the girth as it throbbed in my hand. Mark reciprocated and held my cock in his left hand and started to wank me strong and hard. What a feeling to have another man feeling my rock hard cock. The girls had stopped what they were doing to watch Mark and I. They cheered us on. "More , more more" they shouted in unison. It felt so sexy to have them as our audience. I got down close to Mark's cock and took it slowly into my mouth. It felt big and strong but natural too. The girls loved the sight of their two men getting it on. Lin came over our side of the tub to check out me sucking hard on Mark and Nickki approached to have a close up on Mark wanking my cock. Nickki came lower and Mark guided my cock into her mouth and wow she sucked and sucked on my cock. Lin had helped herself to Mark's huge member too taking it out of my mouth and so this festival foursome continued. I sat up and then pushed Mark's cock into Lin's open mouth. After getting close to coming in Nickki's mouth I held back and suggested the girls stood up and bent over the side of the tub with their arses ready for a good doggie style finish. I stood up and before I could do anything Mark decided to reciprocate and took my cock in his mouth. Nickki and Lin were loving this hot tub man on man session. We then mounted each others partners and then swapped over and back again.

"Suck our pussies" begged Nickki. I bent down and sucked at Lin's open pussy and tickled her arse with my tongue. Mark and I swapped partners again and repeated the action. The girls were certainly enjoying the fun. It was all too much for us boys. We both stood up and I drove my cock into Nickki from behind and held on to her fantastic arse. Mark was looking after Lin in similar fashion and as if by some game plan we all came together. Roars of passion and energy. A full swap with a fantastic finish watching Lin impaled on Mark's cock whilst shooting my load into Nikki from behind. We were all relaxed and exhausted and collapsed back into the water to catch our breath for round two.
