Under normal circumstances, Liu Yiru would have refused, but the stimulation from the couple outside and her son's persistent caresses had left her burning with desire.
Almost against her better judgment, she agreed, guiding her son's hand from her chest to her groin and saying, "Good boy, help mom here. Just touching the surface won't be enough."
Ye Fei was overjoyed.
He gently pulled aside her soaked panties and placed his fingers on her wet, throbbing core, teasing the slit.
"Mom, is this your pussy?" he asked.
"Naughty boy, don't use such vulgar language!" Liu Yiru scolded, though she was blushing at the lewd term. She playfully pinched his member before continuing to stroke it.
"Alright, I won't," Ye Fei grinned, slipping a knuckle into her tight, tender opening and moving it gently.
He noticed that while her outer warmth was higher than other women's, it didn't reach the intense heat he felt deeper inside.
