A high percentage will do this for you buddy
It is not " a high percentage" at all.
My AW saved search for 18-35 yr olds in London returns 3944 results.
When I filter it by those who offer Swallow (at discretion) it is 917.
About 23%. Except the reality is going to be lower as all the PG scams / camwhores tick every like.
A fit, young, enthusastic prossie who swallows is a real gem for sure.
