Megan then surprised herself by joining him on the bed and slowly slid...ng back the sheet to allow his now fully erect cock to spring free. She then carefully wrapped the black silk and lace panties around his shaft and began to slowly stroke it. "Megan, you have to stop." "Why? Doesn't it feel good?"
