Okay, this is the cheap way xD
I use 2 balloons, you can adjust them to any size
I like to use saliva on them to make them slippery (or if you have any baby oil...)
Try it, it really feels good and it feels like a pair of big tits (with even nipples
)
Seriously, that's what I do :boobies:
PD: Now, can you tell me the name of the girl being titfucked in your avatar?
