Belldandy walked to the bed and Urd got up to greet her. The sisters looked each other in the eye, sending a mental signal between them. Belldandy looked away and blushed while Urd smiled softly. What happened next returned life to Keiichi’s spent penis. Urd placed her arms around Belldandy and kissed her. Gently at first, but growing in intensity and passion. As they kissed, Belldandy’s hands began to rove over Urd’s naked body. She moaned into the kiss when Belldandy’s hands found her breasts. Before it could go on any further, Urd pulled Belldandy away from her body. While they kissed, Keiichi had been lying on the bed with his member slowly rising.
“You’re ready,” Urd whispered to Belldandy before giving her a small push towards Keiichi. The two looked at each other for a moment, nether moving or saying a word. Then when it seemed Urd would have to intervene to get them started, Belldandy started to undress. Keiichi’s eyes took on the sight of Belldandy’s slowly undressing form and his penis became fully erect.
“This is my first time,” Belldandy said softly and Keiichi nodded. With how pure and sweet Belldandy was, it came as no surprise that she was a virgin.
“I’ll be gentle,” he reassured as he got out of bed and embraced Belldandy.
“Fuck me, Keiichi.” Keiichi's dick stiffened immediately at her words, this was he only time she hadn’t called him ‘Mr. Keiichi’. Positioning himself at her entrance, he hesitated, making sure she was ready for him. Belldandy nodded and closed her eyes. Very slowly, so as not to cause her any undue pain, he began pushing his way in, an inch at a time. Belldandy stiffened, the feeling of something so big inside of her was different, almost painful, but felt good as well. As he finally buried his full length inside her, she let out a sigh of pleasure at being filled. Her train of thought was interrupted as Keiichi began to slowly withdraw, the movement bringing his groin in contact with her clit, sending a shiver of pleasure through her.
"Are you all right?" he asked, concern clear in his eyes. Belldandy only smiled, letting her actions speak for her. She raised her hips to meet his, driving him deep inside her in the process. Taking this as a sign to continue, he began moving his hips in time with hers, sliding slowly out of her before pushing back in. The two lovers slowly sped up their pace, getting faster and faster, his thrusts getting harder and more forceful until he was fairly driving in and out of her. The slapping sounds of good wet sex filled the room, joined by Keiichi's moans and Belldandy's soft cries. It didn't take long for the pair to reach their limit.
Keiichi grunted as he went over the edge, his dick twitching inside her, sending load after load of semen into her sex. Belldandy was only seconds behind, as the feel of his cock pulsing inside her triggered her own orgasm. With a loud scream, she clamped her legs around his waist as her internal muscles squeezed every last drop out of him. Completely spent, Keiichi collapsed atop her, and they simply lay there for a few moments, exhausted. As soon as he could muster the energy to do so, Keiichi rolled off of her to lay on her side. Belldandy let out a small moan as she felt him pull out of her, and then turned to wrap him in a loving embrace.
Urd, who had been standing in the corner watching, walked to the bedside and sat down next to the panting pair. Lightly she brushed her sisters long brown hair out of her eyes and smiled down at her proudly. Her sister had finally taken the final step in love and become not only Keiichi’s girlfriend, but also his lover.
