Vacuum Insert
Push soft belly,
air remaining inside
can be pumped out
This idea is brought to us from Madrid Airport
where doll package was squashed by a truck tire
receiving no damages inside at all
① Place Insert into position lubricated |
②  Push the soft belly down to squeeze air out |
| ③  At the same time put the cock tip at the entry like above |
④  Release hand so that cock starts to enter |
⑤ ...and penetrates deeper |
⑥ ...enjoy to&fro movements |
| ⑦  finally finishing proudly as the model cock |
Right ! the soft belly "sucks" your cock instead of "blowing" |
