After two modeling sessions at the local college, I had one more to go. The second session had ended up with the class tricking me into giving them an erection, by the attractive instructor putting me in a comfortable reclining pose and then quietly and slowly giving me a pantiless upskirt view. This brought me to a raging erection, but then class was over and everyone went home. A few days before the third and final session, she called to say she wanted to use two models, and could I recommend a female model I'd worked with.
Well, since the class had tricked me into having an erection (normally forbidden or at least not to be planned for) I decided it was my turn to pull a trick on them. I knew several women who would welcome the money for modeling, but here's what I did: I gave the instructor my wife's name (different last name) and mobile number. She had modeled professionally years earlier, but wasn't now on anyones' list of models. "Here's a new model who may be interested."
The call was made, and my wife agreed to pose with me. At home we practiced a few standard dual poses, and on the appointed evening we showed up, arriving a few minutes apart. We tried acting like we were just meeting for the first time, and acted respectful of each other. We used the changing room in turns, and then both came to the posing platform. Dropping our robes, we tried to act slightly embarrassed, even loudly asking each other where it would be OK to touch (arms, hands, legs, back, head only). I noticed several more students than the small number of girls from the first two weeks. Maybe the word had gotten out there's be a female model, because now there were several boys, too. You had to be over 18 to be in this class. This would be a two-hour session: short gesture poses for sketching, a break, then a long pose for painting.
