So this huge black man knelt between my spread thighs and took very slowly my hard cock into his wet, warm mouth. I knew he was skilled in giving oral...sex to another man…He started to suck on me so well, that I only could close my eyes and moan.After sucking me for a long while, he stood up with his massive black cock in hand, asking if I would like to suck on him…I did not even say a single word; I just leaned forward on him, to take his huge hard cock in my mouth. I began licking and sucking. Sarah is very submissive and likes to be told what to do. “so why are you here?” I asked, I could see her cheeks colour and she squirmed a little in the seat as she was shy about answering despite both of us knowing the reasons. I wanted to hear her say it. “errrrm you know!” she said in a timid voice, “do I?” I questioned, “ I may suspect but I need you to be clear about what we are doing – you do know why you’ve just sat on a train for hours don’t you?” “I’ve come to see you” she tried to.

Then I moved to down, she was wearing track pant, I removed the lace of the pant and slowly by kissing her waist and thighs I removed her pant, by this time she removed my jeans, my dick saluted her as I was not wearing any underwear, she took it in her hand and complimented me and kissed it but refrained from doing blowjob as she was uncomfortable with it, so I didn’t force her.I was completely naked but she was in her bikini, I struggled to remove her bra at once, but she guided me and I.
