They simply saw you and Rick, or possibly me, heading for my office during the dance. That is not a problem. I do think they might actually snoop arou...d here so I would suggest that we move our fun times to another location. I even expect them to follow me and may have actually followed me tonight for all I know. If they do snoop around here, I have a plan and I want to share that with you now..."*****************Linda, as planned, made a point of visiting Karen at Karen's house, actually. I raised and started the shower and had nice bath, which refreshed me. Before quitting the bathroom I took Didi's gown, bra and panties. Cleaned all my semen from them and put them on other cloths as it was before.After that it was my favourite way to masturbate in the bathroom. Off course! I was able to do that only on Sunday because Sunday was holiday and only that day Didi and me happen to be one after for bath. I would never wake up until I see didi enter in the bathroom so it was obvious. I was watching a late night film that showed a lot of naked girls, this had got me hard. When my sister sat beside me, she immediately noticed. I tried to will it to go soft, but the more I tried the harder and bigger it got. I don't remember any words that passed between us, but her hand reached out and rubbed me. I do remember the look on her face, it's a look I've seen many times since; her eyes wide in disbelief, lust and desire all rolled into one. I just sat there while she unzipped me. He pulled back enough to withdraw his nuts from my mouth and his dick slid fully off my face and in one swift motion, he lined up with my still open mouth and pushed his cock inside. With his hands on my head, he began to face fuck me, pushing his cock into my mouth with deep, needful thrusts. I fondled his wet balls while he used my face, but he wanted a bit more submissiveness from his new found cocksucker."No hands," he said. "Put them behind your back and keep them there."I did as he.
