The Malesation Traveller is a practical penis pump that you can take on any trip.
Simply turn it up to the full size and it's ready to go when you are! Extends to 21-cm (approximately 8.25-inches); opening is 8.5-cm (approximately 3.3-inches) and includes a travel bag. From your church to your front porch, you can pretty much use it anywhere.
It even collapses for discretion's sake. What are you waiting for - get to pumping!
