I turned back, and without a word, Rachel closed her lips around my erection, now throbbing painfully from such a long stimulus without being allowed ...o cum. Quickly, methodically, she squeezed and sucked powerfully, drawing my sperm out of me until with great relief, my balls loosed and I was spurting my load down Rachel's throat.She drank and drank and drank, swallowing every drop. And when I finished, she merely licked her lips then stood up and kissed me gently. She was still fully dressed.. "Oh Josie you really are nothing but a little tart now, hahaha, there is nothing but a sissy girl left. I love the hair, its perfect to show you off. You see I noticed that because you have been kept as a woman all these years that you were getting a little confidence and frankly making it very easy for you to blend in and pass as a middle -aged female."She went on to say, "But now you look like a female that is a total bimbette, a women that is trying to be young and looking very inappropriate. As we were behaving much better towards each other than we had done before our relationship had progressed to sex, our parents had decided to go away for the weekend, leaving myself and Sue to look after ourselves, with me being in charge. Yeah, like that was going to happen. I may have been in charge as far as Mom and Dad were concerned, but Sue had her own ideas about that.We stood at the gate early one Saturday morning, watching as Dad finished checking the car, and making sure everything. After checking out from the counter she said bye and she walked out of the supermarket.I went to my car and put all the grocery into my car and while I was taking my car out of the parking lot I see her, she was standing outside of her car and was talking on the phone. I got out and I asked her if she need help.I pulled my car where she was standing I lowered my window.Me: do you need some help?Aunty: no I am fine. You go ahead.Me: why are you giving me such attitude. I am just trying to help.
