Could it be rape?

Marci had liked him. When she met Kirk two weeks ago after a party at a fraternity house, he was attentive, caring, and eager to know all about her. He was willing to talk about himself and his feelings. They had gone out twice during the next week, and on their second date, they had spent almost an hour kissing in his car in front of her campus apartment. Just kissing, that’s all; she was pleased that he didn’t seem particularly aggressive or interested just in sex like so many of the other guys she had dated. The next weekend, she invited Kirk over to her room for pizza and a movie. After dinner, they began kissing on the bed, and his hands began to wander. Marci stopped him and told him that she wasn’t ready to be sexual with him. He said he was sorry, but as the kissing continued, he began to force his hands under her clothing. The more she protested, the more forceful he became. She told him no and pleaded with him to stop, but he was bigger and stronger, and with all his weight on top of her, she just felt powerless. She tried to fight but couldn’t. For some reason, she didn’t call out for help. He got her panties off and his pants down and pushed himself into her. When he was done, he told her how great it was and actually wanted to kiss her. When she told him to get out, he acted hurt, as if nothing wrong had happened. Could this be called rape?
