Since you've never known Matt to lie you just sit there on his bed while he undresses. It would be foolish for you to try anything. You didn't want to be turned into an inanimate object or an animal. Being a girl was bad enough. You looked at Matt and shuddered a bit at the thought of having sex with him. It was difficult for you to just sit there but you did.
Matt took off his boxers and you could see that his dick was already hard. He came over and began rubbing your breasts. Your skin is much more sensitive than it had been when you were a guy. You close your eyes and enjoy the sensations coming from your breasts. You could feel a warm feeling building up in your groin.
Matt moved one of his hands down to your pussy and starts to rub. The sudden increase in pleasure caused you to squeal a little bit. The warmth in your groin grew and it was spreading through your body. Matt kept this up for about twenty minutes though it felt much longer than that. You could feel that you were really wet down there. Matt stopped rubbing you and laid you down on his bed. You opened your eyes and looked at him as he spread your legs. You hate yourself for wanting him in you but you do.
Matt slowly slides his dick into your vagina. You had expected there to be some pain as Matt broke your hymen. However all you felt was pleasure. This same thing had happened with your ex-girlfriend before. You were curious about it so you had done a little research on the net. You found out that girls may not be born with intact hymens. Even if they were the hymen was likely to be worn down. The pain most girls felt was more than likely due to not being aroused enough to be properly lubricated instead of their hymen being torn or stretched. You must be aroused enough.
Matt started to fuck you and you closed your eyes in shear bliss. To your mind sex as a girl was much better than sex as a guy. Matt was going slow and waves of pleasure were radiating throughout your body. You started to moan in pleasure and brought your hands to your breasts to knead them. This heightened your pleasure and you moaned a little louder. You were getting so hot that you were starting to sweat a bit. In just a couple more minutes you moaned loudly as you had your first female orgasm.
After about another half hour Matt started to speed up. You could only assume that he was approaching his own orgasm. You were quickly approaching another orgasm yourself. You moan loudly as you orgasm and you could feel Matt's dick spasm as he orgasmed. You could feel his sperm hitting your cervix.
Matt pulled out and collapsed onto his bed. You feel really relaxed and wide awake. That was the best sex you had ever had. Maybe it wouldn't be so bad to stay as a girl.
