She told Jenny that they were going to do what they had talked about and she was expecting her to get a really good video for their Term Paper. Turnin...g back to me she asked, You dont mind jacking off in front of two 16 year old girls, do you? If it will be too distracting for you we can leave and let you talk and video it for us, if youd rather? Debbie and Jenny both had looks on their faces that were saying Please dont make us leave? Please let us stay and watch you jackoff your gorgeous cock. I said to her, "You seem to be enjoying your job." "WhenI get to show people attractive, stylish shoes, I do," she answered. "Sooften people only come in for butt-ugly shoes."We thanked her for her help and paid for our purchases. As we walkedthrough the mall, we passed a clothing store that carried plus sizes. "Ihave an idea," Linda said, and she led me by the hand into the store andover toward the skirts. With her infallible radar homing, she found abright red knit skirt in my size. It was. "White hot lightning bolt of complete embarrassment as I froze in mid-hipthrust then turned around with my nerves jingle-jangling all over and mybrain popping like flashbulbs going off. Big sister Emily stood therein the door I'd so foolishly left slightly open."The things you see when you forget to knock," she said."I was... just..." I didn't know what I was doing. Well, I knew. I justcouldn't come up with something to excuse what Emily had already seen.My face felt like someone's mouth. Are you going to cum?” She asked. “How do you hold on so long? Jon is finished in 30 seconds.”“I could finish quickly too but I have trained myself to hold back.” My balls were now slapping on her wet buttocks as I had increased the speed and the length of my thrust.” I knew that the side effect of holding back the way that I had was that when the time came it sometimes took longer than I wanted.I kissed her again to try to increase my stimulation. She responded passionately and pulled me hard.
