In our group of a dozen or so open-minded artists, we take turns posing one another. Some weeks it's my wife's turn among the seven or eight women to be the female model, and I usually assist by holding her legs and/or labia open whilst others guide the male model's cock into her to get the pose just right. We set up several poses, all showing his cock just entering her so we have good views of the penetration. Once coupled, the models hold the pose without moving, then we reposition them for the next pose. No fucking; just artful placement of body parts. In, hold for ten minutes, out, change the pose, repeat. For two or three hours. Sometimes the male can't make it through the whole session, so in a typical evening I might end up helping guide more than one cock into my wife. Of course, all of this takes place under bright, soft lighting.

The women each seem to be able to handle the full three hours, but most times it usually takes five or six men one after the other to perform all the penetrations required, all with that week's woman. The women seem to always be ready and to have great endurance; not so the men.

(To clarify, when you're not the model, you're helping position the models, then standing at your own easel painting or sketching.)

We sometimes start with the prepared female in position, open and ready, then guide the male's member into her. Other times we might position the male first then lower the female onto him. We males aren't always ready with an erection, but the females seem to always be wet, especially after one or two penetrations. Lots of artistic variations; never any fucking. Like fitting Lego blocks together: Insert Tab A into Slot B.

Extremely shy when not actually in a pose, when the session is over my wife immediately puts on a robe, likewise during the breaks. She's a model, not an exhibitionist. And mine is the only cock that gets to 'bottom' out or ejaculate inside her.

Anyway, back to the main theme of this thread: I have indeed helped guide other men's cocks into my wife's vagina. We are artists.
