"Cottie Brown had been involved with the defendant Alston for roughly six months. They shared an apartment, and when they fought, she would live with her mother until he called to ask her to return. Brown testified that at times she had sex with the defendant to "accommodate him." On these occasions, Brown would "stand still and remain entirely passive while the defendant undressed and had sexual intercourse with her." She testified that Alston beat her on occasion and that she left the apartment and ended the relationship after he struck her when she refused to give him money. Alston appeared at Brown's technical school a month later and prevented her from entering the building and grabbed her arm, saying that she was going with him. Brown agreed to walk with Alston, and he let go of her arm. Alston stated that Brown was going to miss class that day and threatened to "fix her face" to keep Brown's mother from continuing to interfere in their relations. Brown told him that their relationship was over, and Alston replied that he had a right to make love to her again since "everyone could see her but him." Brown agreed to give Alston her address in an unsuccessful effort to persuade him to permit her to return to school. They passed a group of Alston's friends and finally arrived at the home of Lawrence Taylor. Alston briefly went to the back of the house and, when he returned, asked whether Brown was "ready," and she replied that she "wasn't going to bed with him." Brown complied with Alston's order to lie down on the bed, and the defendant pushed apart Brown's legs and had sexual intercourse with her. Brown testified that she cried, but did not attempt to push Alston off her. They then talked. At some point following this incident, Brown let Alston into her apartment after he threatened to kick down the door. He spent the night and the two made love several times. The defendant testified that she did not resist because she "enjoyed it."

Was Alston guilty of the rape of Brown?
