Neither of these occasions involved alcohol.
One of my mates once grabbed my wallet and shoved it down the front of his jeans as a joke. I suggested that he either give it back or I would retrieve it myself. As he didn't comply, I wrestled him to the ground, shoved my hand down his jeans and got my wallet back. Of course I copped a feel too!
This same friend also stayed over one night. I gave him the option of the sofa bed, but he said he would share mine as it would save having to make the other bed up. Well we get in bed but he kept his boxers on (I always sleep in the buff). I made a comment at one point that boxers in bed were for wusses, and he said he thought it was best he wore them to keep the donkey under control (his wife now refers to him as donkey dick).
Anyway, I needed to go to the toilet, so as I was getting heading to the bathroom, I told him that if he hadn't removed his boxers by the time I got back, I'd remove them for him. I got back into bed and we was lying on our sides facing away from each other. I reached back with my hand and said, "Don't worry, I just want to check something". I ran my hand down his back to his thighs and he was still wearing his boxers!
"Erm, what did I say?"
"Okay, for heaven's sake, I don't know what the big deal is!" he grumbled as he took them off under the covers.
"Satisfied?" he said.
"Yeah," I replied, "that's brave!"
"Nah," he replied turning over onto his back, "THIS is brave," he said, and grabbed my hand and placed it on his dick!
That was a GREAT night!!!
There was also another friend who posed for some photos for my drawings. He didn't want to do any full nude shots - which was fine with me, but after a while, he said he didn't mind doing some if I needed some. (this sometimes happens as models begin to relax and realise it isn't that nerve-racking!)
Well I finish off the 4th roll of film and say, "Okay I think that's it." He was still lying on the sofa stark naked and said "Are you sure there's nothing else you want to do?"
I walked over to him, smiled and said, "I thought you'd never ask."
"That wasn't what I was meaning," he said laughing
"Maybe, but you aren't running away either."
I think the next thing I heard him say, was something like "Oh fuck, yeah!"
That was a GREAT afternoon!
Both blokes are now married with kids!
