Hi Lisa, welcome!
I wrote one about a month ago that may or may not interest you. It's called "n2oh!!!" and I posted it in three parts. You'll have to go back about 4-5 pages to get to them. Here's a brief descrip so you can decide whether it's worth the clicks:
A guy and two girls (all three in their early twenties) experiment with laughing gas and the two females (who are both bi-sexual) consent to being tickled, one at a time, by the other two. I, personally, would describe the climax in part 3 as "hot", but check it out and see for yourself. I included some hetero and lesbian love making which is why I'm recommending it to you.
Peace
