No comment was made about this and we seemed to go an as before.Throughout our whole lives we had played together, tickling, wrestling, pushing each o...her around and generally never hesitating to lay hands on each other in fun. I found that Mike hands were starting to find their way to forbidden places and linger longer than they had before and it was as if he was replacing his loss of 'voyeuristic privileges' with his grabby/feely groping. Often either of us would hide and spring out or sneak. We had a clear view straight up my wife's dress as she negotiated the steps. We could see the whole of the length of her tapered slim legs, the stocking tops and suspenders. The upper reaches were shadowy but the panties were clearly new. Like the suspender belt they were pale lemon and very sheer. The clearest view was of her beautifully rounded tight little bottom as the rear panel of the panties was transparent, the front was lacy but I couldn't see clearly. Sandy was easily old enough to be. On Monday night, I went to the kitchen to get some juice. As I passed through the living room I noticed Sis was sitting on one end of the couch in just a nightshirt and panties. Her right knee was raised against the back of the couch leaving a good view between her legs. I went back to my room, removed my sweatshirt and pants, then put on the nightshirt she left on Saturday. I already had a pair of panties on.I went back into the living room and sat on the other end of the couch with my left. She was very horny. So was I. I was sucking her boob like a hungry child, the only difference, it was for pleasure, extreme pleasure. With my hand, I spread her legs and raised her dress a little high. As expected, usne panty bhi nikal diya tha. I started rubbing her pussy and slowly slide 2 fingers inside. I was fingering her passionately while still sucking her boobs vigorously. She came close to my ear and said “2 finger se kya hoga, kuch mota feel krao”. Fir kya tha dosto, me to wahi chahta.
