My 1st bi experience part 2

So with Chris now going limp he got off the bed and said he was going to clean up, which left Mandy and me alone, I still had a very hard erection, and beckoned her to come back on the bed with me, once on it I lay her down and started to kiss her with tongues, her hand fell to my erect cock and mine to her hairy pussy which was now pretty wet. I slipped a couple of fingers right up to the knuckles and pushed them in and out in a slow rythm, my fingers coated in her juices, then Mandy asked me to go down on her, which I was only to pleased to do, she smelt very pungent but not in a dirty way, I licked her hole her, clit and smothered my face with her sexy scent, I did this for a few minutes and then Mandy pushed my head down towards her anus, and told me to lick it, I had never ever licked a bumhole, but so aroused I thought why not, so i tried pushing my tongue up her bumhole, making my tongue stiff it penetrated a little way, she seemed to love it, i made her wet with my saliva and slowly eased a finger up her anus, god she loved it, she reached under her pillw and produced a dildo, try this she said , it was pretty slim but about 8 inches long, I eased it in and to my surprise she took it all, only the balls were sticking out of her it looked sexy as hell. Then Chris walked back in already erect again, he said to Mandy you suck his cock , and I will fuck you, and with that he got between her legs and slipped his cock right up her pussy, up to his balls in 1 thrust, I knelt beside Mandys face and put my cock in her mouth, she sucked it eagerly, I reached down and played with her tits, but with her sucking my cock and watching Chris bang the life out of her I could last no longer, I announced I was ready to blow, and asked if I could shoot on her face, she nodded so I pulled from her mouth, and shot it all over her face, she looked sexy plastered in my cum, I looked at the clock and I had had 75 mins with them not the hour I had booked so decided time was up, not them they said I could stay until Chris had cum, but I didnt want to take advantage. I was a little disappointed I had not got to fuck Mandy, or indeed to have my cock sucked by Chris ( this has now happened) so I dressed and as I was leaving, they saw me to the door, Chris still erect and Mandy in just bra and stockings, I kissed Mandy goodbye and gave Chris a little rub on his cock, and that was that, money well spent.....
