"fuck..." Riya cursed while lying on top of Kevin, breathing heavily. Her thighs still tightly squeezing Kevin's penis, which was oozing semen onto her thighs. Kevin looked at her with a smirk, and she blushed as they shared a moment of post-orgasmic reflection.
'We... we kissed,' she said to herself with shock, finally realizing the forbiddenness of what they had done. The taboo pleasure had transformed into guilt as she felt the sticky, hot liquid on her thighs and Kevin's semi-hard penis trapped between them.
Before she could fully register it, Kevin's lips were on hers again, and his tongue was playing with hers. At first, Riya responded out of surprise, but then her annoyance grew. She pushed him away and firmly said, "Stop kissing me." saying his, she started to get up from him.
Kevin flashed a sly grin and, with a teasing tone, replied, "Why, my dear big sis, what's wrong with a little kiss between brother and sister? It's all in good fun!"
