Mum loved it, of course. She got all coy and silly when he came on to her like a horny boy. I figured he was trying to tell me something rather than h...r, but I couldn't help feeling jealous.We sat down to eat, Mum and Dad sitting right near each other, Tim drawing his chair close to mine. Dad paid no attention to me at all, and Tim did the opposite. He couldn't stop engaging me in conversation, and in the meantime his hand searched for mine under the table. I withdrew irritably. Nothing. The thin material did little to disguise the mass of his member. I felt the heat coming off him.He stirred.I quickly removed my hand, both from him and me.But he didn't wake. He just moved his head so he was now 'looking' away from me.After a minute of doubt I once again placed my hand on his crotch. This time he didn't make a sound.I allowed my hand to rest on him as my other hand slowly stroked my rock hard cock.Gently - almost inperceptively I started to move my hand over him. I could feel. We went down stairs and got something to eat I felt so hot walking around the house in a robe and panties that I got a hard-on. Mom sent the two younger boy to bed not long after they came in the house and sis went up not much after she was out of the bath room. Then Mom and Dad said that they were going to bed and for us not to stay up to late. After they were gone, I sat on the chair across from the one that bro was in and let the robe fall open. I could see that he was getting a woody and I. Truth be told, I was hoping for a repeat of the previous week's teasing, but she never looked my way. So I quietly resigned myself to enjoying the memory. She chatted with her friend, crossed and uncrossed her long legs, and occasionally brushed her hair back. I simply watched her, with only half my attention on Gabriel and the Scharffen Berger chocolate he was talking about.I was most of the way through my second drink when I felt the need to use the restroom. I set my pipe down, took the last.
