But she seems bewildered about some of those particulars. It seems from her account that Jerry was not only nervous but hesitant about explaining what... was happening last week. After prodding her about particulars it seems she thought boys could cum at will. I set her straight and even volunteered to physically show her the fundamentals. Wow Katie was all too eager for a lesson. She was a little cautious when I required her to be partially naked; she bought the “mental stimulation” theory. So on. Closing my eyes as I did so conjured up just the one image of Linda lying naked, parting her thighs, revealing her sex, touching herself, rubbing herself, sliding a finger or two inside herself while her thumb toyed with her clit. And what was she thinking about as she brought herself pleasure?My penis was enormous, throbbing for release, and in a mad moment I wrapped the sweatpants around myself and started jacking off like a monkey. I was going to blow a big load right on that swath of cloth. And Candice replied asking, just how are you wanting to punish me. I thought about it for a moment and then while stroking my hard cock, I replied saying, I'm gonna make you kneel on all 4s like a dog, take my hard cock and enter you from behind, spank your sexy ass while I fuck you hard and rough. In anticipation I awaited her reply while jerking my cock and then to a fright my bedroom door opened and my sister walked in on me playing with my cock. Oh shit sorry she said and turned around back. The sheet settled lightly over Lila again, as the palms of Janet's hands under the sheet were brushing the insides of Lila's thighs. Janet leaned over, lips parted as her mouth opened. She swirled the tip of her tongue around Lila's swollen clit, making contact through the sheet. Lila twitched every time that tongue made contact. At last, Janet started to pull the sheet down, from the bottom. The motion of the sheet sliding against Lila's very aroused flesh was like a thousand tiny fingers.
