The week was quite smoothly going - apart from the constant horny feeling I was with the encasement I was locked in, some thoughts here and there when... I thought I would have seen a strange look at me form colleagues - but then again ensuring myself from the fact that no one knows what is underneath, no one knows what goes on in my mind all the time ... and surprisingly I got myself somewhat under control as for the hardons I got so many times at the begin - that imprisonment, that pain it. Hope I am supported by the ISS family.This is RidingWood (My pen name for ISS). I am based out of Bengaluru and if any chick or aunty wants some action, they can email me. Don’t worry, will have my email address shared by the end of this narration.I’m 5’8, with a lean and athletic physique and my tool is 5-inches long. I am a little dusky, but my dick is an authentic Dravidian dagger! Coming to the story, this is about the sexual encounter I had with my cousin sister (she’s family, so I’m not. And..” I screwed up by saying ‘and’“And what Jack?” As she caressed my hand.“..well you know yesterday..”“Yes I remember that, but I didn’t expect to get you like you did. I mean only my legs where showing.”“…uhh.. well I saw your panties as well and so I’ve been thinking about that too and that’s why I’ve been like this since I woke up. “She just laughed and said:“Well I didn’t know my panties where showing. I didn’t mean to show that.” And I saw her faced blushed.“Well listen jack, I’m OK. The rubber dildo was trying to finds its way in, my legs were stabilized so I couldn’t really help. The dildo went a bit in, and I felt as my but hole was ripping open, I bit my lip very hard in pain. I looked over at my Mistress and only noticed she replaced the candle near her now and I was in complete darkness, she was watching how my ass was ripped open for her. She probably liked what she was seeing as she thrust herself on me, the dildo entered deep in me, I felt my ass widen hard for it.
