I'll explain the rules, its pretty simple really. The game begins with three or more players. For this example let's say a threesome- 2 male and 1 female. The two males are the 'strokers' and the female is the 'strokie' Wine and dine the female. Humour, heart felt intimacy and a hardon is always a great start. Get her comfortable enough to accept some passionate kissing, a massage with extra benefits, a find and grind etc. You know the drill. Once she's in the groove, flip her over onto her hands and knees. This is where the game really begins... The dominant of the three (you already know who that is) of you takes position kneeling behind the strokie and inserts his manhood. Then he begins to take ten strokes. Once he has finished his ten strokes, he is to pull out and move away for the next stroker to take his turn of the strokie. The next stoker, then takes ten strokes in the strokie and then moves aside for the next to take his turn. 10 strokes is called a round. Round two. The first stroker at the beginning of the first round takes his turn again but another ten strokes are added. He then begins to stroke twenty times. Then pulls out to make room for the next stroker to take his turn. Each round, another ten strokes are added. First round- 10 strokes each. Second round- 20 strokes each. Third round- 30 strokes each Etc... Etc.. Got my drift... Fortunately/unfortunately there has to be a winner...a loser... and a prise. The loser is the first stroker to cum. In my honest opinion for this game there are no losers. I'm sure you can understand ; - ) 4) Now it's up to you as to the rules. The winner now has the right to cum in her pussy.... mouth... or ass. Depending on the agreed value of the prise at the beginning of the game. Its not rocket science... Lol... Side note. If you want to mix it up, depending on your relationship and experience. ~ You could have her call out each stroke. ~ Assert to her that she is not allowed to cum until the winner takes his pleasure in a hole of his choice. ~ If/when she she does loose count or orgasms, the penalty for her is that the game begins again at ten strokes each But... For each next consecutive stroke a spank is added to her ass. If she fails again... The game returns to 10 strokes each and a firmer punishment is added. ~paddle ~Crop ~whip And so on.. It can be made made a game of edging to the extreme. If you want it to.... Don't be afraid to add a little dirty talk if it is a heightening element to play. Why not put her in a spreader bar over a love seat for a harder pounding. Use your imagination and a few toys from the draw to really make it a worthwhile game to play for all involved.
