I watched them both for about five minutes, my cock fully erect and straining to get out of my trunks. I was feeling a strange kind of excitement although here was this unknown man giving my girlfriend a good shagging and going by the noises she was making, obviously enjoying it.
I was also trying to take in the situation and how this man came to be here. Perhaps the guy had knocked twice on the door as I said I would and at about the time that I was due to arrive. Jen was blindfolded as we had arranged so she didnβt realise it wasnβt me. The guy then noticing this woman dressed as a schoolgirl and blindfolded, took advantage of the situation.
The guy was now starting to make grunting noises and very soon reached his orgasm, shooting his semen into Jenβs pussy. He continued pumping her pussy for a while making sure she had taken all his semen and then pulled his cock out. I then noticed the guy was wearing a condom and it was hanging down full of semen. He pulled the condom off his cock dropping it to the floor and then bent down to pull up his trunks and trousers. At this point I went into the bathroom and pushed the door over in case he decided to make a quick exit. After about 15 seconds the guy emerged from the bedroom and opening the front door, left the flat closing the door behind him.
I immediately went into the bedroom and saw Jen lying on her side. Her hands were still tied behind her back and she was still blindfolded. I found a tissue and quickly picked up the used condom and returning to the bathroom, flushed it down the toilet. After washing my hands I returned to the bedroom and took the belt off Jenβs wrists. I sat her up taking off her blindfold and gave her a big cuddle. She looked at me with a big smile on her face and said that she had really enjoyed that. She was unaware that it had not been me giving her a good shagging, but a complete stranger. Jen than told me that she needed to come and asked me to masturbate her with her vibrator. She laid on her back, spread her legs and pulled her white panties to one side. I lay down beside her and taking the vibrator started rubbing it gently over her clitoris. In no time at all she had an enormous orgasm.
To this day I have not told her what actually happened but am thankful the guy had the decency to put on a condom before fucking her!
