One of my friends was always horny, she would just randomly start humping, with the technique called the straddle and hump, while you were laying down or anything.
So later on one day we were in her basement and she was dancing. I told her she was going to be a stripper one day cause she was always so horny. I said give me a lap dance so I can she if your good or not,(I was pretty horny myself) and she did. she put me on the couch and moved her hips in a circular motion moving on my hips. Every once in awhile she would grab my boob and lick it. She then grabbed my pussy and I was so surprised. I orgasmed quickly because she was rubbing my clit and she was humping me. Then she told me to give her a lap dance, so as she sat on the couch I put my knees around her thighs and started humping her and then I touched her pussy as she did to mine. So I started rubbing it and then I took off my shirt and let her lick my nipple. I rubbed her pussy and humped her while she was sucking, she obviously orgasmed quick too. Then she told me it was my turn again and to lay on my back. She straddled my waist and layed down. She put her finger up me and started humping. Then we both started humping each other really quickly (just in our underware now so I could feel her wetness) and grinding on each other's pussies. I stuck my finger up her and she moaned. Then I turned onto my stomach and she started humping me from behind and we were dripping wet. So I reached down her pants and fingered again her until she came into my hands like crazy. So we both got fully naked to do it again, our pussies were rubbing together and we took turns sucking each others tits. Then she fingered me again, it was amazing, then she brought her pussy up to my tit so my tit was tickling her clit. She orgasmed all over my chest and I licked it up.
Other times I would be laying on the couch with a pillow on top of me and we would hump each other through the pillow and grind on each other.
One time I was bending over and she came up behind me and pulled my pants down, she grabbed my hips and humped her pussy into me until I orgasmed onto the floor. We're not gay or anything, we're just horny. When she's not around, I grab a volleyball and put my naked pussy onto it and hump quickly until I orgasm, it works fantastically.
