She said the lecturer beat her up last month when she confronted him at the college for avoiding her, adding that the case was already at the Ilese Police Station.
However, while Adu admitted to having sex with the 28-year-old, he insisted that he used contraceptive, saying the lady seduced him and he gave in to the temptation.
Mosunmola told our correspondent that she underwent a three-year course at the college, adding that several lecturers had asked her out before Adu, but she refused.
She said, "Dr Adu is the Oral Health Coordinator for the college. During my three years study, he taught me two courses each semester. I have never failed his course.
"When I got to second semester, 300 level, he awarded me 38 in one of his courses. I went to his office in August 2016 to know why I failed the course. I needed to pass all my courses to be able to go for my board exam.
"He asked me if I thought I could just come to the school and go like that. He said if I dated him, he would waive the course. He said he didn't approach me in 100 level because another lecturer was interested in dating me.
"The lecturer he mentioned told me in 100 level that it was either I paid him money or used my body to pass his course. Because I didn't agree, I failed his course. I didn't pass it until I got to 300 level.
"I told Adu that I would date him, but I didn't want to have any problem, and he assured me that there would be no regret."
The victim said the lecturer took her to the office of the Head of Department and after some discussions, it was agreed that she could sit for the board exam.
After the board exam at POGIL College of Health Technology, Oke-Eri, Ijebu Ode, on August 21, Adu, who was among those on the panel, was said to have given Mosunmola some of his practical instruments and a laptop for safekeeping.
However, Mosunmola said when the school bus arrived to take the students back to the school, she forgot to give the practical instruments back to the lecturer.
She said Adu later called and asked her to bring the instruments to a hotel where he lodged.
"I was preparing to leave when he called me back that I would be sleeping over with him.
"I met him with another lecturer in my department. I observed that the lecturer also had a female student with him. From the hotel, we went to different places before we finally lodged in another hotel along Ilese Road. While I was with Adu in a room, my other classmate passed the night with the second lecturer in another room.
"We had three rounds of sex. He didn't release on time. He used two condoms for the first two rounds. The third round was, however, flesh-to-flesh. That was when he ejaculated inside me," she explained.
She said the lecturer dropped her off at home and they continued their relationship, until she stopped seeing her menstruation a few weeks later.
The Ogun State indigene said she became worried after she started vomiting, adding that she took a pregnancy test, which was positive.
She said when Adu heard the news, he reluctantly accepted responsibility, but allegedly gave her a drug, Eprostol, to abort the pregnancy.
She said, "I refused to take the drug because the prescription was not from a medical doctor. He came down to my place to persuade me to take the drug, but I still refused. He asked me what I wanted and I told him that I needed to change my accommodation because the pregnancy was a shameful thing for me. He told me not to worry, that he would handle it. After that, we had sex.
"When he left that day, I could not find my phone again. By the time I got another phone and called him, he started acting funny. Sometime, he would just laugh at me."
PUNCH Metro learnt that several people had attempted to mediate in the situation without any success.
Mosunmola said attempts by Adu's HOD, dean, and provost to mediate were rebuffed by the lecturer.
The victim said she later approached the Human Rights Office of the Ogun State Ministry of Justice at Ijebu-Ode, where a lawyer, one Kolade, called the parties for a meeting.
Adu was reported to have agreed to pay N5,000 feeding allowance per month, in addition to paying N7,000 for ante-natal registration.
After paying the allowance for two months, Adu reportedly stopped.
The parties reportedly held another meeting in March at the human rights office to review the agreement.
Conflict was said to have broken out among the parties when Mosunmola presented a list of things required for her delivery, which she valued at N50,000.
Adu was said to have insisted on paying N30,000, which the 28-year-old refused.
"I didn't have any accommodation and I couldn't buy any of the drugs the doctors prescribed for me. I told him I would only manage the N50,000. He left in annoyance.
"Since March, the lawyer didn't call us back and Adu refused to pay the N5,000 he used to give me every month. I called the lawyer late March and asked him to help me get the N30,000, but the lawyer said I should not call him again," she said.
After reporting the lecturer to the Permanent Secretary, Ogun State Ministry of Health, where Adu also worked, without any result, Mosunmola said she became desperate and went to the college on April 13 when she knew Adu would be taking a class.
She said while pleading with him for money for her medical expenses, the lecturer assaulted her.
She said some people intervened and she reported a case of assault to the police at the Ilese division, Ijebu Ode.
"I am now in my 38 weeks and anytime soon, I will have my child. I am an orphan and I don't have any of my baby items ready. I am begging Nigerians to come to my rescue. I know I have made a mistake, but I need a second chance at life. I don't have anywhere to go. It is a church that is accommodating me now," she said.
When our correspondent reached out to Adu to appeal to him to raise the N50,000 for the baby things, he said he had no money and would not borrow because Mosunmola had turned him to a "cash cow."
He said he had already informed his wife about the incident, adding that there was nothing that could surprise him again as he had lost his credibility over the incident.
Adu said, "She was one of my students; but on a personal level, I never knew her until after they released her final results and she failed some courses, including mine.
"Her HOD asked her to come and ask me if I could waive the course for her. She called me on the phone and came to see me in the office. That was my first contact with this lady. When she made her request, I met her HOD who said I should assist her. He said even if I did, she might not sit for the board exam because of the other courses she failed. So, I passed her.
"When they sat for the board exam, I was surprised to see her and I asked her HOD why she wrote the exam when she had other courses she failed. He said people begged for her.
"After the board exam, she came to thank me for the assistance and she asked to carry my bag and the instruments I used to conduct the exam. By the time she was leaving, I collected my bag from her, but I forgot my instruments with her.
"That day, I went to hang out with my friend at the pool of a hotel where we lodged. Suddenly, I remembered my instruments and I called her to keep them well. But she said she could come to where I was and she came. After dropping the instruments, she didn't leave as I expected and I decided not to bother her.
"We were together at the hotel till evening. One thing led to the other. My brother, she slept in my room that night and we had (sexual) intercourse. This was a girl I never dated or had any relationship with."
He said by weekend, Mosunmola called him that she was pregnant, adding that she later said she was only joking about it and wanted to see his reaction.
Adu said the call made him to stop communicating with Mosunmola and he did not respond anytime she called, until she sent him a text message saying the pregnancy had become real.
He said, "I decided to travel down to Ijebu to see her. She brought out the test result and said I was responsible. I told her I used a condom and she couldn't tell me that my condom burst. She said if I was afraid because I was married, I should not bother because the pregnancy actually belonged to her boyfriend and she merely wanted to see my reaction. I warned her and left.
"The next time she called me, she said how would she take my pregnancy to her boyfriend, and that I should take responsibility for it. She said she would abort the pregnancy if I wanted her to, but I must rent a house for her in Ijebu Ode and then she described the kind of house she wanted.
"When I heard that, I told her to do her worst, because it was obvious to me that she just wanted to blackmail me. She had been going round different places, telling people that I impregnated her. The question I ask is, did I rape her? Did I hypnotise her? You came to meet me where I was and we had fun, and now you are pregnant, and you are telling me I am responsible for a pregnancy I am denying?"
He said before Mosunmola could reach his wife, he quickly reported himself to her and begged for her forgiveness.
The medical practitioner said he reluctantly agreed to pay the N5,000 after much persuasion by the human rights lawyer, adding that he regretted the agreement because Mosunmola used it to make more demands on him.
"When she brought the list for the baby things, I asked her, 'Why are you making me as if I am the father of your baby? Am I your husband?
"She suddenly flared up and said I should even go away that she didn't want anything from me again. She cursed me and after that encounter, I decided to stop giving her anything," he added.
He said Mosunmola came to attack him during the lecture. He said she was about stripping him naked when he forcefully detached himself from her.
Adu explained that the case of assault against him at the Ilese division had been thrown out after he told the police the student was the aggressor.
"People impregnate people and nothing happens. Why is she treating me as if I had done something criminal?
"The worst that will happen now is for me to die. I am not a young man; if I die, people will cry and I will be done.
"But I also ask myself, what if the pregnancy is mine? My prayer now is for her to deliver safely and we will determine the paternity of the child," he said
