Not much a fantasy but an actual workout. Since - as my handle implies - I enjoy pleasuring women orally. Being dominate, I enjoy prolonging it. Sometimes mixing pain in it. A lady fried of mine wanted to lose weight and tone up. I promised her pleasure, but she had to endure much work. One time on the bench - her legs spread - she is forced to lift weights while I give her a good tongue lashing. She must keep up with the reps. If she stops, a leather strap is planted on both inner thighs, and then she must start over. Probably the best hour workout I have been to. At the end, red welts on her thighs, dripping with sweat and screams of estacy!
