Your cum and more

"Well, after hearing what you said, it seems that you may not be opposed to me using this as an educational experience."

"Oh how so?" I asked looking at curiously.

"Well, first of all, I have always wanted to try some cum. I have heard so many different descriptions of how it tastes that I want to have some personal experience. And since I seem to be lacking a boyfriend......"

"You want to try my cum. Seriously?" I responded incredulously.

"Well, if it is okay with you." I looked towards Isabella to confirm what I thought I was hearing and her look of shock, likely mirroring my own, confirmed that I wasn't dreaming.

Turning back to face Jenna I said, "Actually if you want to, feel free. I think it would be interesting to watch my little sister taste my cum." Blushing she looked down to the rapidly cooling cum on her abs. "If you are going to taste it, I would make sure to get it while it is still hot. Cold cum isn't a fun substance to deal with."

Still hesitating, Jenna simply stood there in front of us hunched up in embarrassment blushing all the while. Clearly that was enough of a motivator for my best friend, sorry, girlfriend, to channel her inner helpfulness as she carefully climbed off of me trying to avoid crushing my balls. Walking up to Jenna cautiously, she knelt down in front of her and grabbed Jenna by the hips. I simply watched in fascination trying to figure out what was going on with my new girlfriend and why she was kneeling, naked, in front of my cum soaked sister. But it was only a short couple of seconds until I got my answer.

Sure enough, Isabella leaned in and licked a the longest line of cum on Jenna's stomach gathering it on her tongue as she went, startling Jenna if her sudden gasp and flinch was anything to go by. But she didn't pull away. Reaching the end of the line, Isabella stood up and looked Jenna straight in the eyes before leaning in for the kiss.

If I could be anymore astounded then I already was, this was it. Because not only was I watching my naked new girlfriend walking around in front of me, but I had just watched her lick my cum off of my little sister and then offer it to her in a kiss. At not just that, but with a glance at me and a small smile, my sister accepted the kiss with enthusiasm as she began making out with my girlfriend right in front of me. If I wasn't hard before, this definitely was all I needed to get the blood flowing and get myself back at full attention. It had to have been almost a full minute before they finally broke the kiss and both turned back to face me grinning from ear to ear.

"You taste pretty good Johnny. I didn't expect to be quite like that. I also didn't expect to check two items off of my bucket list at once."

"Did you say bucket list?"

"I definitely did. I have a list of....shall we say sexual exploits.....that I wanted to do before I got locked down to one guy for my whole life "

"May I ask what is on that list or does that have to remain secret?" I asked trying not to laugh at the slight ridiculousness and awkwardness of the whole situation. I mean, I was laying on my side on the couch completely exposed to my sister for the first time in my life. She still had some of my cum on her stomach and my best friend turned girlfriend was also naked in front of me after having brought me to orgasm with a marvelous handjob.

"Well, obviously trying cum was on the list. Kissing another girl was also on the list. And um well, the third is a little awkward for me."

"Well, don't feel embarrassed to tell me. I don't think there is much that could embarrass us anymore at this point."

"Well, I want to give a guy a blowjob."

"Okayyyy....what is the problem with that. Many girls want to do that."

"Well, I was wondering if you would let me try on you. That is where it gets a little weird I guess." she responded nervously as she seemed to curl in on herself.
