I had started some fairly regular meets with another mature bi-guy off the SH site; we got it together quite well, pushing our boundaries a little farther to the point where he would take me up his arse. His attempts to enter me were frustrated by my incredibly small sphincter, coupled to his short but very thick cock, a joy to suck, but a fearsome weapon to push in anyone's bum. He called round one morning, and while we were getting naked, his mobile rang. He turned to me and said 'It's Rob...he can make it now...happy?' We had often discussed a 3-sum, but arranging one was never easy, but having got in touch with another of his mates, Rob, Jon was about to deliver. 'Sure...great....does he need directions?' Silly question, really, Jon had already told Rob where we were. We lay on the bed gently sucking and wanking, me getting quite hard at the anticipation of a third body and cock. It was an anticipation well rewarded: Rob was in his late forties, slim, easy-going, and with a long thin cock. Completely shaved, his smoothness was totally erotic, a contrast to Jon's rough hairyness. Rob offered me his semi-hard tool to suck, as he leant over and took Jon's rigid cock in his mouth. I felt his hand seek out my balls, then slowly finger my anus; one finger, then two. Rob's cock left my mouth as he repositioned himself between my legs, slowly wanking my six inches as he rimmed me with saliva, his two fingers pushing deeper inside me: I felt some mild pain, but enjoyed the feel of him more. Whilst this was taking place, Jon had positioned himself behind Rob, and after very little foreplay but much gel, eased his fat head into Rob's bum. 'Lucky bugger', I thought, 'being able to take that!' It soon became obvious that Rob was enjoying his shafting from Jon so much that he forgot me, his fingers slipping from my ring: The language was unbelievable as Jon thrusted faster and harder into Rob, eventually shooting his load with a lot of noise. I could feel sweat dripping onto me as Jon slowly allowed his softening tool to slip out of Rob's arse, a small blob of cum still leaking from his huge bell-end. 'Let's give it a go, old son....'.taking the tube of gel, Rob squirted a fair amount in my hole, easing it in with not two but three fingers; - a further blob on his thin but hard purple tip and my legs were lifted up and apart as he eased his cock into my bumhole. At first it would not go in, but moving his torso in a circular motion and thrusting harder, I felt the tip of his weapon ease past my tight ring. Yes, it hurt, but not screamingly: With a gentle to-and-fro motion he pushed further into me until I could feel, through the mild pain barrier, the head of his cock up against my extremity; he stayed still, whispering to me to feel the hardness filling my being, then said 'I'm going to start fucking you until I fill you with my spunk.' For several minutes he worked his tool inside me, until a quickened thrusting told me he was cumming. Contrary to what I have heard, I could'nt feel his sperm spurting inside me, but a little later I could feel it slowly leaking out of my now very-sore bum. His discharge was also very noisy, and when he withdrew I was keen to see his still-hard cock glistening with a mixture of lube and cum. My cock had softened during my thorough shagging, but regained it's firmness in time to enter Rob's bum: His second load of the morning was delivered in less than a minute, as I felt myself shoot not just spunk but a whole new experience into his rampant sexyness. I still can't take Jon's big member up my bum, but a more recent anal experience with a smaller cock since has helped me join the forbidden pleasures elite, and looking for more. Yes, it was bareback, but then any encounter 's risks.........
