My girlfriend Lesley and i went to Rhodes last month for a weeks break. She is 46,attractive and tall with long straight natural blonde hair and a slim body with pert breasts. We have been together 15 years and have an okay sex life but i have always wanted to share her. It seems most of the guys on here say the same. The holiday was great but there were no real surprises. We were at apartments in Pefkos near the beach which were nice. We know the place and the people well. Day 4 and we had been sunning ourselves all day. Returning to the apartment we showered changed,went down the village for a meal,a few(quite a few)drinks later we returned back. The apartments had a pool which was softly lit and obviously empty. It was 1am. There was nobody around,we were both quite drunk so we stripped off to our pants/knickers and bra and went in for a swim. About 20 mins later we were sitting on the pool edge when a couple we vaguely knew wandered past.We had spoken to them last year and chatted to them in the village a few times this year. He was helping her along as she was clearly suffering from one too many shots or cocktails. We all laughed as he took her back to their apartment. 10 minutes or so later we were still talking when he(Mark)returned with a bottle of Sambuca and some shot glasses. He had on a pair of shorts. We all had several shots and gradually all ended up back in the pool. We were throwing a childs giant beach ball at one another,just mucking about really. I climbed out of the pool to nip to the loo's across the other side. As i clambered out Lesley swam over and yanked my pants part way down. I grabbed her and as we grappled her bra came unclipped. She was still laughing. She jokingly called me a few names then as i held her bra away from her she cupped her breasts and ducked down in the water. You couldnt see her breasts now. Mark laughed. I hung her bra from the strut of a sun canopy and nipped to the loo. Lesley was giggling and laughing,she called out that she wanted it back when i returned. I was gone about 3 or 4 minutes i guess. When i returned i came around the other way in order to surprise her. As i wandered past the bushes to the far side of the pool i could see her leaning back against the pool wall with her hands holding the pool edge. I couldnt see Mark anywhere but it was very dimly lit. As i looked i could see a shape beneath the water in front of her,i stood still and stared then realised it was him beneath the water right in front of her. His head rose slowly upwards and they started snogging. He had clearly been sucking or licking her breasts. She has very sensitive breasts and nipples. If you touch them,lick them or gently stroke them she becomes instantly aroused. At no point did either of them look in the direction i had gone. He was doing something beneath the water as they continued to kiss. Then i saw her head go back and realised he was fucking her. In his right hand were her knickers. My still soaked pants were sporting a rock hard erection as i watched him really fuck her hard and fast. He grunted and slammed up and in to her several times then relaxed. She pulled his shoulders towards her and they snogged for a second or two then they both peered towards the direction of the loo's. He part swam part walked backwards in the pool,she was clumsily trying to put her knickers back on whilst staying upright. I gave it a minute then noisily wandered back over to them. He left a bit sharpish saying goodnight and i slipped back in the pool. We started kissing and i pulled at her knickers,she started to say no but i forced them down and off. I got her against the pool edge,she parted her thighs and i slid right up inside her. As i fucked her hard i thought of him doing the same. She soon started to cum and i was close too. Just as she started groaning i whispered that i had seen them both and that she was a very good girl. She came hard and i pumped my spunk up inside her a second or two later. We were kissing and she was saying sorry. She sarted crying and i told her it was absolutely fine. We shagged several times that night and the rest of the holiday. The guy (Mark) and his girlfriend are returning in September and i have booked us the same week. We chatted with them a few times before we all left to come home although nothing was mentioned about the night of fun. I made sure he knew we would be there in September too. I told her i want to share her with him fully. She initially has said no and said it was a drunken one off but gradually over the past few weeks she has started talking more and more about it. As we are shagging i whisper that i want her to suck his rock hard cock until he comes in her mouth. At this point she always cums and i am not far behind. She said his cock was very thick and that it felt as though he had stretched her. Neither of us can wait till September.
