I do not believe that Sisera would have lain with Jael for several reasons. First, he was on the run. He had gotten his chariotte mired in mud and his army was being routed anyway, so he jumped from his charriotte and ran. When Jael saw him, I'm sure he was filthy and exhausted and looking for someplace to hide. Since her husband Heber had a friendly relationship with the current Jabin, I would imagine that Sisera kind of knew who she was and felt safe enough to take refuge in her tent since he had said to her that if any man should ask her if there was a man in the tent to tell them no. He was intent on hiding, not having sex. Also, he was extrememly thirsty and in heavy armor of the period. Under those conditions I do not think lust would have been foremost in his mind and Jael was probably a very pios and upstanding woman. She would not have entertained the thought of having sex with a dirty, smelly man whose filth would mess up the tapestries of her well made bed. Also, she may have felt a strong allegience to Barak and Insreal and not to the Jabin so she already had in mind to act as an ally in the Campaigne and not a conspirator with Sisera. He asked her for water but instead she gave him milk which I thought was curious, but on further thought, warm milk would have served to soothe and relax him and put him in a position to want to sleep as opposed to being refreshed, as what water would have done. She needed him to sleep in order to carry out her assasination plot.
