"Not only is a pussy better than a cock at giving pleasure to its owner. A pussy is also better at giving pleasure to another woman. A pussy can fuck another pussy better than a cock can fuck a pussy."
Their good natured bantering certainly had escalated. Joe and Katherine were lucky enough to have found another couple they truly could call "best friends". Each couple enjoyed the others' company at least once a week. They talked on the phone and text messaged constantly, spent Thanksgiving, Christmas and New Years' together, and often went on vacations together.
All four were young, extremely good looking, and energetic. Joe and Katherine were computer programmers who worked out of their house. Their friends were both research scientists at the local university.
Although all were sexually adventurous and open minded, the prospect of mate-swapping was out of the question. Because the other couple's names were Linda and Grace. But there was no reason a lesbian couple and a straight couple couldn't be best friends, and they were.
Best buddies sometimes tease one another, and Joe and Linda relished doing it. But always in a good natured way, while Katherine and Grace looked on. Joe - knowing full well it wasn't true - would tell Linda that neither she nor Grace would be lesbians anymore if he could make love to them. Linda in return would threaten to convert Katherine, steal her from Joe, and make her part of a threesome.
The teasing went on in a harmless way until one day Joe laughingly said that anything a lesbian could do - go down on a woman, or use fingers to bring her off - he could do too. But he also could use his cock to give her the best orgasm possible. So men were better than lesbians at making love to women.
That's when Linda said it. "Not only is a pussy better than a cock at giving pleasure to its owner. A pussy is also better at giving pleasure to another woman. A pussy can fuck another pussy better than a cock can fuck a pussy."
Startled, Joe replied, "You mean you can bring Grace off better using your tongue and fingers than I can bring Katherine off with my cock?"
"No. Actually, yes. But what I really mean is, well, two things. First, I do think most lesbians are better at oral sex or manual sex than most guys are at oral or manual sex, or intercourse, and that I can bring Grace off better using my tongue and fingers than you can bring Katherine off with your cock. But my second point, my main point, is that I can provide more pleasure to Grace with just my pussy than you can give Katherine with your cock. I can mount a girl and fuck her better than you can!"
A startled Katherine then asked, "But how could you bring Grace off if you don't use your fingers or tongue? Do you mean with a sex toy? A dildo or strap-on? Or do mean that because you have a pussy, you understand women better, and for this reason whatever you do with another woman is better?"
"No. Actually, yes. Well, what I'm really talking about is tribbing. Also called pussy grinding and scissoring. Whatever name you want to call it, I can grind my pussy against Grace's, my clit against hers, and in this way get her off way better than Joe can get you off with his cock."
After a silence Joe interjected: "Do you mean better than my cock rubbing on top of Katherine's pussy, against her clit? She loves that, so no way. But if you really mean better than me actually fucking Katherine - penetrating her, humping her - it wouldn't even be close."
Grace smiled indulgently at Joe and then turned to Katherine. "Our clits are on the outside. If we were meant to receive maximum pleasure from intercourse, our clits would be inside. But they're not! I wish I could prove it to you. Actually (she smiled again, this time a huge smile) I could prove it to you, Katherine, right now!"
"But I'm not gay. Besides, Grace, you have no idea how much pleasure Joe gives me with his cock", replied Katherine.
"And you have no idea how much pleasure Linda gives me by rubbing her pussy against mine," responded Grace.
Then Linda said it. "I bet I could bring Grace off quicker by tribbing her in the missionary position her than you could bring Katherine off by humping her in the missionary position."
There was a silence. Joe finally replied, "I would take your bet."
Katherine interjected, "So would I."
Then Grace spoke. "And the winners get to so anything sexual to the losers. Anything they want, any way they want."
There was another deafening silence. Then Joe spoke, "Sure. If Katherine agrees."
Katherine looked a bit frightened, "I'd have to let you girls do anything you wanted to me if you win -- you'd probably trib me, right? Both of you?"
Linda replied, "Maybe - among other things. But Grace and I would each have to let Joe - let his cock - fuck us if we lost, which neither of us has done before or - no offense, Joe - would want to do. And Joe probably would want us each to give him a blow job as well as let him fuck us. Am I right?"
Joe nodded enthusiastically. "Yes. One condition of the bet would have to be that the winners could collect any time they liked - not just today. You girls have the advantage that you can come again and again. But, being a guy, I couldn't possibly do the contest, and then fuck Linda and Grace, and also have them each give me a blow job, in one evening. Besides, I would want to look forward to everything. Why don't we give the winners a month to collect?"
"I forgot men take so long to re-charge," said Grace. "How about 3 months?"
Everyone nodded, but then Katherine added, "This contest isn't fair. All three of us girls are seriously risking doing something we've never done. I'd have to make lesbian love, and Linda and Grace would have to make straight love and let Joe cum in their mouths, which even lots of straight girls don't want to do. But Joe isn't risking anything. In fact, he'd love to be fucked by gorgeous lesbians. Right, Joe?"
Joe smiled.
Katherine added, "I'll bet one of you - or both of you - would fuck him with a strap-on?"
