Choose a day you can stay at home and be undisturbed.
Get naked and on all fours. Clean your ass and prepare it for the horsecock.
Gallop through the rooms in anticipation of what is coming your way for 15 minutes.
Now slowly, still on all four insert the dildo, eyes closed, in one slow stroke to its full length in your ass. Fuck yourself with full strokes for half an hour.
For the rest of the day you leave it in an do your daily business naked with that dildo in.
If you need to pee, fill the seringes with your pee, give your ass 100 strokes for one seringe and spill their content in your ass.
You can use white panties to hold that dildo in place.,
