This happened when I was at university a number of years ago and made me realise that sex is fun and always varied. Me, Mike well I was in my final year and I became good friends with my next door neighbour in Halls who was called Rob. The walls weren’t very thick so we’d often hear each other having sex and often talked about it afterwards. We both fancied a student nurse called Julia who we knew loved sex too. After a party the three of us were back in my chatting and it was getting more and more flirty and sexually charged. Rob and I had agreed that if either of us got lucky the other would step aside and leave them to it. After a bit of play wrestling Julia started to kiss Rob and it got more intense so I stood up quietly and went to go. “Where are you going Mike?” Julia asked “I want you both to fuck me if you’re not shy.” Rob and I looked at each other and one of us said “too fucking right”. “Right” said Julia “One rule. You both do exactly as I say and you can fuck me any way you like – are you okay with that?”. Another “too fucking right” and we are soon a naked tangle of bodies. Julia is a mousey blonde with short hair, a smoothly shaven pussy with prominent lips and lovely tits with perky deep pink nipples. Rob 6ft black hair and about 6ins of girthy cut cock nestled in his black pubes. Me 6ft brown hair 7ins uncut but slim girth and fully shaven. It’s not long before I am licking Julia’s sweet pussy and nibbling her lips making her moan. Julia has Rob’s cock in her mouth and he is kneading her tits and tweaking her nipples making her gasp. After a few minutes of licking and finger fucking the first instruction from Julia. “Mike lie down” and she 69ed me. “Rob fuck me doggy style”. We reposition and a steady rhythm is established. Me licking her pussy whilst trying not to get a face full of cock and balls. Julia deep throating me, squeezing my balls and rubbing a finger along my crack. God it’s delicious and as I near my climax I feel Rob beginning to speed up as well. He cums first with a grunt and as Julia squeezes my balls hard I am tipped over the edge and with a cry of “I’m cumming” Julia clamps down on my cock and takes all my spunk in her mouth. Motioning Rob to cum and kiss her, Julia straddles me properly and her cum-filled pussy is pressed into my face. “Taste each others’ cum my lovely boys” she says and as I lick her creampie she snowballs Rob. It was a slightly odd feeling to lick someone else’s cum out of her but the way she was writhing on my face showed me how much she enjoyed it and soon we were rewarded with her cumming noisily and more juices flooded into my face. “That was a nice start boys” she said as we all cuddled and had a drink to recuperate. “Now, who wants to fuck me up the arse first?” Rob said he’d never had anal so I said I’d go first and show him. “Right boys get yourselves hard for me” and as we both started to stroke our cocks Julia said firmly “not like that. Mike wank Rob and then suck him off. You said you’d do as I told you so do it!”. I looked at Rob and we both sort of nodded and I knelt in front of him. As I stroked his semi hard cock I felt it twitch and begin to harden. Working his balls with one hand I stroked gently and it grew ever harder and the tip glistened with pre-cum. Looking across I saw Julia with several fingers buried in her pussy and her other hand teasing her nipples one at a time. A look of deep satisfaction on her face she looked me straight in the eye “now suck him off but don’t make him cum yet.” I dipped my head down and used the tip of my tongue to circle his pre-cummy head. Licking down the shaft I traced circles round his balls and then, sucked one of them into my mouth. Rob gasped as I sucked it gently. “Fuck that’s good” he whispered and I repeated the process with the other one. Julia is now knelt beside me getting a close up of what I am doing and, taking him in hand, guides his rigid cock into my mouth forcing my head down. He’s not long but he is wide and I struggle to accommodate him all but Julia’s hand on the back of my head gives me no choice. “Good boy. You’re nearly ready to fuck my arse but let’s loosen you up first. Lie down on your back and, Rob, hold his legs up.” Julia gets some lube from her bag and liberally smothers my rosebud and her fingers. “If you’re going to fuck my arse then you need to know what it is like with something up yours.” A finger penetrates me easily as I frequently fingered my arse whilst wanking. “This doesn’t feel like the first time something has been up here Mike” and a second finger eases in and she starts to finger fuck my arse with one hand and wank my cock with the other. I’m in heaven and Rob is looking down bemused at the way things have gone from what we expected to be a straight MMF to a bisexual exploration. “Now show Rob how you fuck someone’s arse Mike” and Julia moved to the top of the bed and kneels down spreading her cheeks. I bury my face between her cheeks and rim her before reaching for the lube and smear some into her anus. Slathering my rampant cock I position myself to fuck her and Julia says clearly” talk Rob through exactly what you are doing as he will be doing it soon and we both want him to get it right” she said. “Keep her cheeks parted Rob, and gently ease in letting her get used to each inch of you cock slowly. Ease out a bit and then press forward a bit more and you will feel her dilate and relax a bit. Slow and steady does it mate and listen to what she, and her body is telling you and with that I am now fully buried into her tight arse and I begin to fuck her slowly. Julia moans and presses back as I reach round and squeeze her tits and pinch her nipples. “Fuck yes Mike that’s good, now your turn Rob” and as I begin to ease out she firmly says ”no you misunderstand Mike, keep fucking me. Rob I want you to fuck Mike’s arse at the same time.” We both look horrified but before we can say anything Julia firmly said “you promised to do what I said so do it.” “Sorry mate” said Rob a he positioned himself behind me and begins to rub some more lube into my already slippery and slightly dilated arsehole. He’d obviously listened to what I’d said as I felt his broad head press up against me and a moment later it is in and I gasp. I pause fucking Julia and Rob eases more of his hard cock into me until I feel his hips against my cheeks and a steady motion sets up – me fucking Julia and the forward stroke and Rob fucking me on the backward stroke. I reach under and tease Julia’s clit and she shudders as her orgasm builds until she collapses forward spent and I unload in her arse. Seconds later I feel the warmth of Rob’s cum as he fills my arse with his load. We again collapse on the bed in a sweaty satisfied heap and Julia smiles at us both and says “you didn’t expect that did you? I love watching men get it on for me and you two are going to keep me amused for a long time to come. Now Rob clean Mike’s cock up as you’re the only one who hasn’t given a good suck yet.” Rob takes my semi hard cock in his hand and within seconds it’s in his warm mouth and beginning to harden slightly. We kept this threesome up for the rest of that term and eventually persuaded one of Julia’s nursing colleagues, Hazel, to join us and introduce us to spanking, strapons, CBT and the joys of light BDSM – but that is for another day.
