1. To be honest, I'm not necessarily "looking for ideas" (I've got my own ideas on this), but I am curious to see what thoughts people come up with on this concept.
2. Good idea - probably the most interesting - although rather than a word limit, I'm inclined say something like "20 - 30 sentences".
3. Write a full story - I would be really impressed if someone actually did that in response to this 'prompt'.
“Sweet lady, I am torn, most terribly ashamed, but a most dreadful need has arisen - literally - else I would never even think to ask. Alas! I must not! Forgive me!”
“Good sir, whatever is the matter? I see that you are in great discomfort, and I hate to see it. How may I be of aid?”
“Blessed damosel! It is my cock, grown so hard now, so violently enraged with lustful need, that I’m sure it will burst if not tended to. I fear, though, that no cure exists save the warm grip of a virgin cunt, one such as your own. I beg you, part those fair thighs so that I might ease my too swollen member within for a brief moment’s respite.”
