This basically the opposite side of my original thread "What did suprise/shock you?"
So as a gentlemen and the thread owner let me start with mine

Please feel free to add every "I shocked her" stiuation
Of course shocking part was at the end and actually not very much related with the previous sex actions but I know you people like to read so here it goes...
Many years ago I used to see a girl although I have a girlfriend. Ok basically I was cheating my girlfriend with this cock hungry young chick. Shame on me. Anyways.. although she was a virgin her every other part other than tight pussy was an open access. Including her ass hole.
One day we set a date in my home after work. We headed in my room as soon as she arrived and get into business directly. First I undressed her while kissing and groping every body part. Then she gave me a nice masturbation show which she likes veeeery much. Then fucked her own ass hole with a roll-on in front of my eyes (this was a first time I saw her anal masturbating)
Most of the time until then I was only jerking to her sexy shows. After couple of orgasms she started to show her oral skills. I couldn't say she was the best oral sex I had but she used to love to suck cock soo much that her ambition to fill her mouth with my cock always excited me. Generally oral sex session was the last stage of our time together since she was virgin and that was the best way to finish myself but since we had plenty of time that night I decided to fuck her tight ass for the first time. She obeyed and enjoyed it too in screams.
After couple of hours passed with the things I've described above I decided its time to give her the money shot. At that specific moment we were on my bed so I stand up and make her stand on her knees in front of me. My intention was to full her mouth with my hot cum but since she didn't like it very much she was trying to convince me to come on her tits. Because all through this argument I was also jerking and time to time she was was sucking me I gave up to avoid exploding before deciding where to come

She said she wanna lay down on bed so I said ok. To make it clear in your mind situation was like this; We were on my bed. She was lying on her back totally naked and I was standing up exactly above her my foot on her sides. As I keep jerking to her very naked body under me she was watching me and playing with her tits (which again she used to like very much) Not much time passed and I started to cum which is the surprise part for her. Now I wasn't holding my self for days for that night but since our all over erotic play time took couple of hours and I hold my self whole this time I gave her a full 10 seconds of cum rain. From first to the last drop she never moved or blinked an eye. Just laid down and enjoyed every drop of cum shooting out of my cock on to her. When I finished she exactly like "WOW". Her whole chest, tits and stomach was covered with my sperms. While she looks her own body covered with so much cum she was still telling me she couldn't believe how much I shoot. Later she confessed that she never had that much of come on her body before.
Sorry that I can't post any full pictures of here here but just for a bit of spice I added a picture of her two reactions from that exact time (yes from that exact time because I was recording every second with my camera

). Above picture is her "shocked but so happy" smile while my sperms raining on her body and the below pic is her surprised/evil grin just after she realized how much her whole body covered with my cum.
