It was some years back when this took place. I had just returned home and walked into the house, and as I passed the living room, I saw my wife sitting on a chair adjacent to the couch. On the couch was our Baby sitter, Kathleen, a statuesque auburn haired, green eyed beauty of a girl, a college sophomore. No doubt, this girl could have been a model or on the cover of any number of magazines, even at 19!
Kathleen was on her stomach, wearing a pair of sweat pants and a college T-shirt with a school name on it., I saw after she got up later. I then noticed the black cylindrical case that contained the rectal thermometer we used for our daughter, as well as the small jar of Vaseline on the table next to the couch.
I watched intently as my wife lowered the co-ed's sweat pants down, exposing a pair of tight fitting white panties, and a pair of beautifully tanned, long legs. Next my wife lowered the delicate garment peeling it down and leaving the panty resting behind Kathleen's knees. This beauty gave new meaning to "tan lines"!
Taking the thermometer out of the case, my wife held it up, read it, shook it down, placed it on the table. Taking a tissue, Linda, my wife, dipped it in the jar pulling it out with a dollop of Vaseline on it.
With her thumb and index finger, she spread Kath's cheeks, and at that moment, I saw what the adage, "The carpet matches the drapes!" was all about. I spied her spread legs and the tuft of reddish hair between her legs and the swath that ran up between her cheeks. After rubbing the Vaseline coated tissue on the girl's anal orifice, Linda retrieved the thermometer, repeated spreading Kathleen's cheeks and I watched as the silver metallic bulb entered her rose bud opening, the bulb being inserted and buried as it entered her along with an inch or two more of the glass rod with its red dotted top.
Removing her thumb and index finger, Linda let the cheeks close on the instrument, remaining there for about three minutes. Then Linda pulled it out, wiped it and read it. Next she wiped Kathleen's anal area, and pulled her panties and sweats back up.
This happened because Kathleen was supposed to sit for us that evening, but on arriving was coughing and as Linda said, "looked flush", so she decided rather than take a chance of the baby getting anything, felt it prudent to get our sitter's temperature. Kathleen as my wife said, "not so much as a peep out of her objecting". She did take the temperature and Kathleen was at 101.2F, so it was decided that she'd not sit, but we'd pay her and on a future visit when better she'd do a free sit. Now that she was again clothed I entered the room, and feigning ignorance asked what was going on. Linda told me, and I wound up taking Kathleen back home in my car. We called her Mother, explained what had on, and the next time we saw Kathleen was about two weeks later, and in good health.
