Even if your dїck is long enough, you’d probably only get the head of it in your aŠŠ and bending it around to do so, would eliminate the possibility of keeping an erection.
You wouldn’t be able to fụck yourself, only stick the head in and out of your anụŠ.
You could “clone” yours, make a mold of your own ḕrḕctїon and then produce a duplicate of it with silicon.
Not very effectively.
If you want to feel what it’s like to be fụckḕd with your own dїck though, there is a way.
