I always wondered what lesbians do during sex.

My wife and kids are out of town this holiday weekend visiting my inlaws down in Florida where they retired. I had planned on cheating on her. She really pissed me off a week or so ago. So, you know, fuck her. Anyway, so last night I'm out cruising the bars -a rare occasion for me- and things were looking kind of dismal. Thought about getting a hooker, but I told myself that I shouldn't do something that risky. Might catch something and pass it on to my wife. Anyway, at the third seedy dive I get to, I meet this lesbian couple. One was a fox, and the other one was plain and mannish. But after we got to talking and tossing back a few, both of them looked hot to me. They were fun girls. No doubt about it. So I end up at their place. A really nice apartment (why do gay people always seem to have nice things?). We have more drinks. Smoke some really awesome bud. The next thing I know I am bed with them,all three of us naked. Here's the thing: everything we did was oral. They got each other off, they got me off, I got each of them off, by way of human lips and tongue. So seeing as I have never had sex with two lesbian before, is this normal? No penetration on my part. I wanted to of course, but I got so caught up with what we were doing, I thought fuck it, go with the flow. I was hot as a pistol. I still wonder is this how lesbians do it?
