So this has been a dream of mine for quite some time ..
This fantasy requires an extremely large Female bodybuilder .. 6 foot .. 230 pounds .. Think Amazoka in 6 inch heels ( she is 5'7 bare feet )
Standing in front of her she would slightly bend her right knee reach down and pull my 5'8' frame up and on-top of her massive quad muscle that I would straddle while holding on to her massive upper body traps, neck and arms .. She would keep her hands on my waist and simultaneously flex her quad muscle and pull me up and down her well oiled leg while my feet dangle and I ride her thigh .. my body going up and down with each flex of her quad .. until completion ..
Not sure if there are any women who would or could do that ..
