She hid the pains of her young heart under a sincere smile, and ...o one had noticed that something might be wrong. Only Geneve queried once, for she knew her sister well enough to notice the unfamiliar sad twinkle in her eyes.

She started talking again while I continued fucking. Some five minutes later Cathy stopped talking again. I was enjoying this fuck and didn't stop. After about 30 seconds of silence Cathy asked quietly, "Are you...are you having sex with my s*s?" I kept stroking as I thought about my answer.

I thanked him and he told me I was more than welcome.We boarded the bus just after the sun had set. It was dark on.
