I was due to go out to a company social event with my girlfriend. I arrived home slightly late and had to rush to get a shower and something to eat before she arrived. The doorbell went, I answered and she was stood there looking fabulous in a white dress, slightly tanned with no stockings on. I apologised for being late but when I opened my wardrobe door, the shirt and trousers I had chosen required ironing. I set up the ironing board in just my boxers and started to iron the shirt. My girlfriend commented on how it turned her on seeing me doing this. She got up of the couch and walked over and moved behind me.
She started to kiss my neck and her hands moved down into my shorts and she started to fondle by balls. This got me harder and then her hands moved to my dick. Slowly she started to jerk me off and as I got more turned on she got faster. Whispering encouragement to come, her talking got dirtier and her hand went faster. I tried to put my hand in her knickers but she backed off and stopped jerking me. This turned me on even more. I looked down and saw her tanned, manicured hand jerking me off like I did, and I shot my cum all over the shirt I was supposed to be ironing. Needless to say, I did not wear that shirt out.
