"I haven't been doing much exercise lately and I feel tired, so I'll try yoga, which is said to be good for your health." I invited a yoga instructor to my house, and luckily she was a beautiful woman! She was wearing a tight, tight outfit and gave me a close, step-by-step lesson, so I was horny the whole time. And her hand was touching my erect penis... Maybe she was horny too? "Sister, please give me a lesson that feels better than yoga!"
