This is one way I have found to really make a girl horny.
I had been dating my friend for the past four months (now we're just friends). She and I had had sex many times before this wonderful experience.
One morning after she had slept over we started fooling around. We were spooning and she was sleeping but I had woken up. I slowly slipped my hand under the t-shirt she wore to bed and softly rubbed her stomach and abdomen which was so completely soft. I worked up to caress her right breast and nipple which was starting to become more and more erect, just like my penis. I moved closer and pressed my hard boner against her ass. My hand moved down and began pushing away her pyjamas and panties and I slid my fingers through her pubic hair down to her warm pussy. I could already feel her wetness. She then rolled over to face me and pushed down my boxers so we were both naked from the waist down. She started stroking my cock as I rubbed my fingers up and down the outside of her pussy, taking time to press down on her clit and then inserting just the tip of my finger into her vagina, and then quickly removing it, just to tease her a little. We played around for sometime and I suggested she give me a handjob. She agreed but there was one problem, she had no idea how to give a handjob. I really didn't know what to do, so I put my hand over hers and started to manually direct her. It wasn't working, because she was becoming even more bored.
I knew what I had to do. I ignored all my nervousness and removed her hand from my cock. I then squirted some lotion into my palm and lubed up my penis. I then began to masturbate in front of her. I have never seen her so focused in the six months that I have known her. She was fixated the entire time on what I was doing. I even caught her rubbing herself and squeezing her nipples. It was so amazingly hot. I tried as best as I could to prolong the experience, but I was also super horny and wanted to cum badly. So I asked her if she wanted to see me cum, to which she gave a commanding YES!! I applied more lotion and went to work, giving myself another eight or nine hard long strokes and holding my dick tight at the bottom of the shaft at the end of each stroke until I felt my cum begin to build.
What an amazing ejaculation that was. I shot one stream straight past my head onto my pillow, and another two up to my chest. All the while she looked on and picked up her own masturbation. Once I was done and breathing heavy, wet from the semen and sweat, she ripped off her top and bra and rolled over on top of me, pressing herself into my cum on my chest. She said it was the sexiest thing she had ever seen and that she wanted me to play with her. So I rolled her over and began to finger her (with my clean hand). It wasn't long before she was bucking against my fingers and gasping as she came, flooding my fingers with her juices.
It was one of the most amazing experiences I have had.
