Sibling Seduction

... shouldn't have done this."

"But we did," Lily countered, still holding his shaft. He had deflated, but she knew she wanted to revive him. If he'd let her, and she really hoped he would. "And we can do it again. Consenting adults, remember? Please, Simon, please..."

Simon trembled in trepidation, then gave in and nodded. "I never can refuse you."

Lily smiled back, kissing his lips. "I'm so glad to have a brother like you."

They moved together, rubbing their bodies against each other. Simon's hands went to her tits and her groin ground against his. Simon grew hard again quickly at the motions, started to let him take her inside. Then suddenly he pulled back, shaking his head.

"Don't back out now, Simon!" Lily begged. "Come on, please!"

Simon shook his head. "I'm not backing out. Just... condoms! In my bedside table! Help me put one on!"

Lily gave him a relieved smile, then retrieved the condoms as he demanded. I had to insist on these with Levi, Lily reflected as she unwrapped one and rolled it onto Simon's length. She enjoyed the action, pleased with his safety conscious mind. It would also make his semen easy to collect later, she reflected. She would suck it from the balloon.

Simon let the remainder of his inhibitions fade as she sheathed him, fully accepted his sister's attentions. She was stroking him, then leaning into him, surrounding him with her flesh and smell. Lily's hands were on his head while her legs opened for his shaft. Their bodies ...

"You're... looser than I thought... you would be," Simon grumbled as they coupled. "You only did it once with Levi, right?"

Lily nodded her head. "I play softball, remember?" she whispered. "Bats aren't just good for hitting balls." She squeezed his shaft with her loins, emphasizing her words.

Simon's imagination formed an image of his sister curled around a softball bat, pushing the metal club into her loins, using it as a fake cock. He shook the image away. It was exciting, but nothing compared to the reality of Lily joined with him, using his body the same way. "I... I..." he gasped. "I still don't like that we're doing this. But I can get into it. I can get into it!"

"Good," Lily told him, hunching against him, smiling. "And don't worry about other girls. I'm into them too. Maybe we can find one willing to do it with both of us someday. Would you like that?"

Simon nodded. Tess and Lisa were into each other, but had never given him a full on threesome with both of them. If his sister was a more eager bisexual... "Yeah," he spoke aloud. "That'd be great!"

"Knew you'd like it!" Lily laughed.

The next several minutes, they did not exchange words. They were occupied with kissing, spooning, thrusting ...
