My first bi experience ( part 1)

I had arranged to see a couple off the internet who had advertised their services, stating that the guy was bisexual, I had often dreamt of sucking a guy off and thought it would be better in a mmf 3 some. So when the day came for me to visit them, I showered, shaved my cock and balls and set off to visit them. I knocked on the door and was met by Mandy a slim 49 year old lady, who was dressed in white stockings, bra and panties as requested, she was a nice looking lady and my first thought was im gonna fuck you tonight. She let me in gave me a kiss and led me upstairs, I couldnt take my eyes off her small tight bum as I followed her to the bedroom, once inside her husband was sat on a chair in his boxers he introduced himself as Chris.So how do you want this to go he asked, if you want you and Mandy can get to know each other on the bed and I will watch you. So that is what we did Mandy lay on the bed asked me to undress and promptly took her knickers off revealing a hairy pussy, but with bald lips, I quickly got naked and joined her on the bed I leant over and kissed her on the mouth she responded slipping her tongue into my mouth, and I slipped a hand between her legs and fingered her wet pussy, my god I was so hard, I looked over at Chris who was now naked stroking a rather impressive cock and so thick. Mandy instructed me to lay on my back, I did as she asked , she then straddled my face and lowered her pussy on my face rubbing her juices all over me she smelt great and tasted good also, after licking her to orgasm, it took 10 minutes, I felt Chris climb onto the bed, and then his hands wrapped around my erect cock, I froze for a split second and then relaxed and let him wank my cock, Mandy lay next to me and kissed me again i was loving it and then she sat in the chair and left us 2 on the bed, you 2 boys play and I will use my vibrator she said, so we sat on the bed and played with each others cock, both hard as iron bars, do you want to suck me Chris said and I did, so he lay down and said all yours, I positioned my self between his legs grabbed hold of his cock and lowered my mouth down on to it, I dont know how I expected another cock too feel but it was kind of soft texture and hard at the same time, I sucked and slurped at his length like I had seen pornstars do, and after a couple of minutes he closed his eyes and moaned softly, so I knew I was doing it right, I could taste his precum and to be honest I loved the taste, I was cupping his balls and forcing my tongue in his japs eye, I sucked him for a good 15 minutes my jaw was aching like crazy, when Chris annonced he was close, I sucked slow and deep and then he started moaning loud and pulled my head down on to his cock, I shook my head I didnt want him to spunk in my mouth, and he let my head go free, and then his balls tightened, so I pulled my mouth away and slowly wanked his cock until he shot his spunk in to the air about 5 big strings of it, I then continued to stroke his cock and when he had relaxed, i squeezed the last drop of spunk from his cock and slipped it in to my mouth and licked him clean.
