As weird as the situation was, and as much as your girlfriend felt like Jason now, you still found yourself wanting her/him.
"Hey" you start quietly. "Even though this feels gay, does it feel bad?" "What?!" your former girlfriend replies, a little shocked. "Well think about it. This is just what we are feeling. None of this is actually true. I got to admit that just a minute ago, while we were kissing, I actually liked the feeling. Sure it felt a little weird, but the thought of doing something dirty like this actually turns me on. I don't know, maybe I'm the weird one." you finish, trying not to look at her/him directly.
You then feel a hand on yours, and look up to see Jason smiling. "Honestly, I don't think your being weird. In fact I only stopped kissing you cause you looked like you were kind of weirded out. I thought you didn't want to go any further because of how everything felt. But yeah, I am kind of turned on also by how kinky all of this is. Besides, when are you ever going to get the chance to try something like this again?" "Seriously?" you start, now the surprised one. "You really don't mind?"
You look at the young guy in front of you. This guy really is your BF Jason. You slowly lean in and gently kiss him. He responds by kissing you back and soon you find yourself embracing him as he strips off your clothing. After about another few minutes of kissing, he/she stops you. "Hehe, now that's what I expect from my bro. Now things can get really fun."
You watch as Jas moves slowly towards your hard member, and starts licking and kissing it. You lay back and start to really enjoy yourself as he finally puts it in his mouth and begins to suck. The feeling of your best friend's blowjob is amazing, and not before too long you find yourself cumming. You look up to see that he is swallowing every spurt without missing a drop.
Next, Jason climbs on top of you. "That was good, dude, but now it's time to get a little more serious."
And with a smile, he grabs your still hard member and guides it to his pink butthole. You help your best friend by sitting up and grabbing his hips to help aim him. With a little more movement, you can feel the head of your dick start to spread his lips.
In one quick shot, Jason sits down onto your rod and gasps. You had to admit, he was tighter than the girl you knew as your girlfriend, but even so he started moving. As he up and down rhythm got faster, you start to move your hips to match him. Soon you could feel a turning in your balls, and you make your final push towards release. He seemed to be giving signs he was ready to orgasm too. You both sit up a little more while still thrusting and bouncing so you can see eye to eye. While in this position you look into his eyes and the only thing you can see in this big boy is nothing more than your best friend whom you love. With this, the two of you kiss as you explode deep into Jason which brings him over the edge as well.
With the act over, and both of you exhausted, you lay back with him still holding onto you. You can still feel yourself inside of him, but neither of you care. "Now that's what I wanted from a best friend" Jason says. "If things keep going this way, I just might want to stay like this forever." You smile down at him, and pet his head a little. "Well dude, we are on a vacation right now, but when we leave you might have to become that other person again." With that Jason pouts. "Awe, don't bring her up again. I don't want anyone stealing my bro. But then again, if that's what my friend wants later, that's what he'll get."
With all that said, you both drift off for a little nap. But right before your eyes shut you look up and the ceiling and think to yourself. "Does gay sex with your former girlfriend count as real gay love if you actually start to believe the person your with IS your best friend?" You look down once more to see your bro sleeping peacefully on your chest and you realize you don't care, just as long as your in love. And finally you fall into a light sleep.
