I have used that time to explore their underwear drawers and beds, getting naked and cumming in their panties then put them back for them to wear.One ...f the twin’s has a boyfriend and I can tell the difference looking at their underwear – hers is much more skimpy and sexy than her sister’s – silky thongs etc versus cotton panties.A few months ago I went in to the house and heard a noise so I thought the main bathroom fan was running. I walked in to switch it off and there’s she is in her. The sensation was incredible.I showered with cooler water to try and calm myself down. When I was finished, however, Grandpa re-inserted the cleaned plug. My ass felt open and ready and I had months before I would have any kind of sex at all.When my make-up was flawless and my hair dried and curled as Grandpa had instructed me, I had to get dressed. Grandpa had laid out my clothes, as usual. I put on the baby blue dress, made entirely of lace with long sleeves that belled at the wrists. . . I can see her size up his tool with her feet and she begins giving him a slow foot job, Within 1 hard minute of trying to fight the load back, I shoot all into her mouth and at this point Robert has his hands wrapped around her feet and he's using her feet to jerk himself, I use my right hand to jerk the last of the drops out into her mouth and use the left to grab her by the back of the neck with her head in my lap still I whisper in her ear "I'm go upstairs and wash up, finish him off in. . Touching her ass.
