Because everyone is home at the moment, it has been quite a while since I have house-sat for anyone, but I have enjoyed using family, friends and neighbours places to carry out my perverted antics for many years.
Anne is a very pretty widow and near neighbour, that has two married daughters, and our families have grown up together for well over twenty years. We have always helped each other out in our close community, and we have each had the other's house keys as a back up. The last time I got to use her place was when her girls, Kirsten and Katie, took Anne away for a few days holiday last year.
On entering her place, I strip completely behind her front door, leaving all my clothes there. I find walking naked through someone else's place incredibly arousing, imagining they are actually still there and could catch me at any moment, with my shaved erection waving about in front of me as I wander through every room.
I like to play with my penis as I walk, rubbing the head of my cock on doorknobs and surfaces as I go, leaving a faint trace of my body aroma as I go. I sit on everything I can, fingering my sissy asshole then sucking my finger, or roll around on the floor, grinding my throbbing dick into all surfaces, enjoying my kinky routine.
In the kitchen I push handles of utensils up my asshole as I wank, before licking and wiping them clean, I do the same with toothbrushes in bathrooms as I piss in sinks, showers and baths - before I wash the evidence away.

All of this is the build-up to the main event, dressing in Anne's clothes (especially lingerie). Over the years I have been lucky enough to have found the occasional pair of panties left by one of her girls, but as Kirsten and Katie now live in their own places, this is very rare now. It has been a massive turn on to sniff and masturbate in panties belonging to a mother and her two very attractive daughters over the years, and I thank them for unknowingly giving me the means to ejaculate so often.
I like to dress as completely as I can in Anne's clothes, stockings, suspender belt, panties, camisole top, skirt, blouse, but her feet are too small for me to get in to her shoes, which is a great pity, as I would love to complete the look that way. I usually return to Anne's kitchen, to find something to insert up my anus as I finally jerk myself off. Carrots from the fridge feel wonderful up my bum - though whatever I use, I make sure won't be missed, as I always remove the object when I leave.
With my rectum stuffed, and my shaved sissy cock in my hand, I choose a room I want to spunk in (and I have cum in every one of her rooms - four bedrooms, three reception rooms, two bathrooms, kitchen and garden). My only rule here is, wherever I shoot my load, I must remove all traces of it. I usually lick it off any surfaces I cum over, or lap it from my hand if I have been wanking in her bed or on her settee.

Finally, when I have cum as much as I want to, I return Anne's clothes to where I got them from, and go back to her front door naked, to put on my own. Very often, I have returned home still with whatever I used up my asshole in Anne's place, and find that I have to masturbate again once I get in, reliving my wonderful wanking session I have just had in the comfort of her home. It is a massive pleasure to have neighbours like Anne.
