I was wide eyed.. As she said this. I sleep in boxer shorts and since I just got up. Little Micky was up too.. I went to see quickly and put up a T-sh...rt.. She came with following the directions I had told her.. and knocked on my door.. I opened and she was in with a swift step.. “My my… You seem to be all cleanliness master”.. I blushed and said ” can’t help.. I like neat, clean things,, and winked at her”. She smiled and said .. “So what will we be doing today?”. I was again a dumb ass.. So. Jake chuckled, stared deep into my eyes then mouthed the words: “Drop the towel” I hesitated. He mouthed again: “Go on, drop it!” My tummy bubbling almost uncontrollably, nervously and silently I let the towel fall to the floor. “Wow!” Jake’s voice was a hoarse whisper but I heard it. For a few moments I stood naked apart from my short white socks looking down on my gorgeous brother, my knees clamped tightly together, my arms crossed over my tiny boobs. Jake stared up at me, his eyes raking. Shortly after I pulled Tammy’s tits out, one came over wanting to know if he could play with them also. “Are you wanting some cock?” the guy asked after a bit, “I sure want to give it to you, I‘m tired of jerking off.” “We can do that.” Tammy replied. “Let me get more situated.” She stood up turned around, pulled her skirt up, bent over putting her hands on the arm rests of the chair to balance herself if the guy really started to hammer her hole, she spread her legs, reached under pulled her. I reminded him that I am old enough and further more need to learn from other people’s experience. He agreed to tell me the situation so instead of driving me home we drove to somewhere exclusive and began telling me the whole thing.When he first dated her, it was really for sexual reasons. He had not wanted her to be his steady. He already knew she had several boyfriends before him and knew she was not a virgin then. Nevertheless, he dated her anyway. While not dating her, she was free to go.
