A guy I know invited me on holiday with his family during the long hot summer of 1976. I was 18 years old and had been cross dressing for about a year. One of the main reason for going was that I got on well with the guy's grandfather Roy. I suppose Roy would have been about sixty at the time. He was a scaffolder and was very fit. Roy liked to see me in my hotpants and a blouse and really enjoyed my heels. Until the holiday Roy had been content with a stroke of my bottom but things were moving on. I had just started a new job so I decided to invest in some new clothes. I saw a nice pair of white speedo swimming trunks that I thought would suit Roy. They were very brief so if I was going to let Roy enjoy a few favours from me I wanted to see him in the speedos. There were seven of us on the holiday and my friend Jake had his girlfriend with him. The other three we his Mum and Dad, a cousin and Roy. The good thing was that they all went out for the day to the beach or sightseeing leaving time for Roy and me to get together. I must admit I was gagging for Roy's cock and I saw the way he looked at me in my bikini bottoms. It was the first full day of the holiday that I told Roy that I had bought him some speedo trunks and said it was our secret. He was chuffed and offered to model them for me. When it was quiet he slipped into his room and changed. I was invited in and I loved what I saw. They fitted perfectly and with his super fit body he could have passed for a male model. Slim and tanned I thought he was stunning. I went over to him and we had a feel of each other. I ran my hand over his slim stomach and down to the tie cord on his trunks. Undoing him was a pleasure. I could feel that his cock was already erect and I ran my hand down his rock like length. I could feel the veins in his cock bulging to show his manhood. My fingers cupped his full balls and could feel that he was fully shaven. I had had sex with quite a few guys before Roy and I really liked the shaven feel. Roy had his hand over my little tits and opened my blouse. Taking my nips between his teeth he pulled on them and teased them to a full hardness. I knelt down to see him in all his glory while I pulled his bulging trunks down. It was quite hard to remove them because he was so hard. I finally pulled them down slowly to reveal one of the thickest cocks I'd ever seen. In addition he was very long and he was visibly throbbing. His deep red desire was for me. I ran his cock around my face. I did this to all the guys I met because I love their sex juice on my forehead and chin. Roy was starting to drip his pre-cum. I concentrated my hand on the tip of his cock so that I could get a true view of the eye of his cock while it glistened with his viscous sex liquid. I took Roy into my mouth and immediately deep throated his tool holding it at the back of my throat. Roy placed his hands on my head and held me in place. I could feel the strength in his big hands when he slowly rocked my head back and took his cock out and then slid it in again. I nearly came in my hotpants with Roy holding my head and fucking my face. While he increased in speed I unbuttoned my tiny hotpants. I dropped them slighty to show my miniscule knickers. Roy's cock was going down my throat at a rate of knots. I could feel his thigh muscles tighten while he prepared himself for a long orgasm. When he came he filled my mouth and a lot of cum splashed back into my face. It seemed like he was cumming for a least a few minutes. I'd never been on the end of such a torrent of semen. Pulling away slightly he shot his heavy load over my face and into my hair. I was amazed that he was still erect after finishing off. Roy stood me up and bent me over. Searching for my tight shaven ring I could feel his intent. He pulled my knickers down, opened my cheeks and spread my hole. He tongue poked my sex ring. He took of my knickers and rubbed the tip of his cock with them. He pulled me open and I sensed he was seeing how large I could go. Could he fuck me easily and how tight I would be around his mammoth shaft. Roy took me over to the bed and lay me face down. He ran his big hands over my rump and then grabbed my shoulders. I arched my back and raised my arse into the air. He pushed me down from my shoulders and positioned himself with his cock at my hole. I placed my skimpy knickers into my mouth and bit down on them. I awaited his chunky length. Spitting on my hole he rubbed some oil into his cock and slapped some onto my ring. I grabbed the headboard before being ridden. He slowly slipped his meat into me. It was a real stretch and I'm glad I had my knickers in my mouth to gag my panting. He was very masterful with his stroke, a really expert cocksman. I held onto the headboard while Roy was riding me. With his hands around my tits he went deeply into me. I could feel myself jerking and realised that I was shooting pre-cum and it was the first time in my life that I was getting a prostate milking from a hard fuck. I was squirting everywhere which made Roy more excited. He was on the verge of cumming again. I could feel his cock start to expand with the build up of more semen in his tubes. I was slipping around on my sex liquid and realised that I was cumming heavily. Shooting my load into the bed I could feel Roy's semen flow into my body. He reached around a yanked my cock and gave a very hard wank while I finished off my orgasm. I loved the weight of his body on me and his big hand on my cock while he finished off owning me. Roy didn't pull out of me for ages. With his cock up my arse he expertly had a bit of a soft ride in my drenched rectum. When he was finally finished I gave him my knickers as a souvenir. I know from him that he saved them for his wanking sessions and also used them for other conquests that he had.
