Because he was looking at law school, Evan had to really kick ass his senior year. He and Yvonne practically lived in the school's library and supplemented that with either going to other libraries or doing online research. Sex between he and the girls declined to half of what it had been over the summer. It was no picnic for Yvonne, either, as she had two men to keep happy and still keep up with her studies. Thus, it was a huge relief when they finally finished the fall term and now only had four more months of undergraduate life to contend with.

In February, the spring semester commenced. Six weeks later, without telling Robert, Yvonne went off of the pill. The Monday morning she didn't take her dose of contraceptive, she was both giddy and apprehensive. She was happy that she was going to eventually have children for Evan, but contemplating the changes to her body, the hormonal fluctuations, the pain of the birthing process, it wasn't going to be all happy fun time. When she saw Robert that afternoon after they finished their classes, she was extra loving toward him. That wasn't because of any calculation. It was just her mood. "Hey Robert, I'm feeling a little lonely. Could you please come home with me tonight?" Robert, being a red blooded young male, knew what this meant and his cock stiffened as soon as she finished the question. "Poor baby," he sympathized. "I'm totally there for you Yvonne," he grinned. She hugged him and they walked into the library to join Evan, Ryoko and Aolani.

It was hard for her to concentrate, though. Her pussy was wet and aching for cock the whole time she was scouring books and articles for the documentary material she needed. Naturally, Evan knew that this was D-Day for his beloved twin, so when she asked if they could all knock off early and go home, he quickly consented. They packed their laptops in their bags and headed out to the parking lot. Yvonne was all over Robert in the back as the minivan made its way toward their home in very fitful traffic. Robert, in fact, was rubbing her clit while he kissed her and brought her to an orgasm that she endeavored to not be too loud about. "Robert, when we get home, I want you to fuck me right away," she whispered in his ear. "No problem, Yvonne," he assented. That demand made him just that much harder. She could have done him right there, but she didn't want her child possibly conceived on the freeway.

When they pulled into the garage, Yvonne grabbed Robert's hand and they ran upstairs to the bedroom she used when Robert was there. She hastily disrobed and leapt into bed. He followed seconds later and shoved his cock right into her. "Oh fuck, Robert, I've so been wanting you all day," she rasped with lust in her voice. He pulled his cock back toward her entrance and then slipped it back in to the hilt as she surrounded his upper back with her legs. Her ardor flew upward at an almost vertical slope. His cock was already pretty sensitive since his semen had been boiling in his balls for hours. "Oh fuck Robert, oh God, oh fuck!" she whimpered as she felt his spear jabbing her sex repeatedly. Instinctually, she wanted as much cum from him as she could ingest into her womb. She held him as tightly in her arms as she could as he continued to vigorously pork her. She wanted him as deep within her as possible and hoped that she could feel the moment his sperm fused with one of her eggs as he continued his campaign into her inner space. She was about to climax when he had attained apogee himself and they orgasmed together in a verbal gumbo of profanities and ecstasy, his dick jetting his hot sperm sauce against her cervix and, she hoped, into a womb that was no longer protected by the pills.

Her passion was burning like napalm and as soon as he rolled off of her, she had her mouth on his penis, tasting the flecks of semen that dotted it as she orally strove to revive his hard on. 15 minutes later, his soldier was at attention once more and she sunk her cunt on it. She leaned forward and braced her hands on his chest as her hips rocked and circled to stir his cock against her vaginal walls. The heat within her rose again and Robert could see how red her face and chest were now while her pubic muscles put the squeeze on his pole in order to extract more juice out of him. "Oh shit, oh God," she panted, the emotions and sensations conspiring to drive the intensity of her hip shaking. Her body jerked with another orgasm  while he enjoyed the friction from her twat clenching down on his prick.

She smiled as she looked forward to the happy moment when the pregnancy test would read positive, her ass bouncing up and down, up and down, up and down, leaving a trail of her natural lube on his schlong. She felt the heat peaking inside of her again and her breathing lurched and puffed and then the muscles in her groin contracted hard when she came yet again. She was becoming exhausted now and pulled off of him. She got on all fours. He kneeled behind her and restored his weapon to its rightful place in her pink cavern, grabbing handfuls of her hips and jackhammering his spike into it over and over, inspiring her to orgasm again before he injected more cream into her jellyroll.

Knowing what was going on with Yvonne and Robert made Evan horny and envious. He bored his cock into Ryoko's snatch and looked forward to the day when he could impregnate his wife. He cored her up a treat, pounding it into her hard before she went off, her musical panting enhancing the pleasure of the moment before he dumped his ball freight into her pink house.

Yvonne's cunt was on fire for the first few days after she tossed her pills out She gave Robert a good workout doing the humpty dance repeatedly with him. She wouldn't let him cum anywhere but inside of her. It was like she was seeking to get pregnant in world record time. The first week of April passed, as did the second. Two days later, her period was due. Three days into the third week of the month, it still hadn't come. Two more days after that, she got up hurriedly to throw up in the middle of the night and stayed home from school because she felt like shit, telling Robert she probably had the flu. Evan bought her a pregnancy test when he, Ryoko and Aolani returned home and her hands practically quivered when she took it with her into the bathroom. She did as the instructions directed and then had to wait. It was only a few minutes, but it seemed like forever. It came up positive and Yvonne squealed. "Oh my God you guys, I'm going to have a baby!" she rejoiced, practically jumping into Evan's arms. She started crying and Evan and his spouse comforted her.

Evan had to be sure, though, and he had Yvonne make a doctor's appointment, which would be two weeks and change hence. She kept Robert around in case the test was a false positive. A couple of days before the appointment, Evan called Robert out into the darkened hallway of the second floor of his house and splashed the Taiwan native's face with his penlight. "If Yvonne tries to break up with you, you will understand her point of view and accept it amicably," Evan instructed.

The doctor confirmed that Yvonne was with child and was at approximately four weeks. The physician added, "I'd like to see you in another month to confirm a suspicion I have about your pregnancy." "Is something wrong?" Yvonne fretted. "That depends on your attitude. Don't quote me on this yet, but I think you might be having twins," he smiled. "No way! Yvonne reacted and then squealed again in celebration. She went back out into the waiting room, where Evan, Ryoko and Aolani sat. "So what's the verdict, babe?" Evan asked. "I might be having twins!" she exclaimed, her face lighting up. "No way!" Evan blurted. Fuck yeah!" he spluttered, doing a fist pump.

Evan decided to take everybody out to eat to mark the blessed occasion. "So what are you going to tell Robert?" Evan interrogated. "I'll give him the 'I feel like I'm growing apart from you and I need to explore more of life and not be tied down' speech," Yvonne disclosed. "I feel guilty about it because he's a great guy and I'm glad I was with him, but my home is ultimately with you, Evan," she resolved. "Ryoko and I will give you all the support you need," Evan vowed. "I know you will honey," she smiled.

The next time she saw Robert, she took him aside and told him it was over. He understood where she was coming from thanks to Evan's suggestion. They hugged on it and said goodbye. Yvonne still cried . Her and Robert had been together for the better part of four years and it wouldn't have lasted that long if there wasn't something there to keep it going.

What lightened her mood afterward, though, was the thought of presenting Evan with twins. She prayed that her offspring would be as close as her and her brother was. That night, she crawled into bed with Evan and Ryoko and as he enveloped her with his arms, she felt a mixture of apprehension for the ride ahead and bliss. Even kissed her passionately and told her he loved her. Then he curled his other arm around Ryoko and kissed her. "It won't be long before this is you, honey. God, my kids are going to be so killer!"
