California glass wide neck wine jar. Use glass cutter rotating drill to make two small round holes near base. Holes permit finger tip control of pressure inside jar as inserted penis slides back and to in jar neck. You see all of your penis. Lubricate inside of jar neck with varied lubricants, or no lubricant, to vary the stimulation sensations. Any leakage from penis conveniently contained by the jar. Bliss!

My girlfriend has used a cucumber before, stretched her cunt nicely.

Fuck yeah! I bet that was fun to watch?

Where to get a cutter like that, what does it look like?

My wife used to make and altar curtains. One day a lady that she worked with and renting a room from a friend of ours. The lady asked if she could alter her bedroom curtains.
Wife went round and fixed the curtain and saw a cumber on the bed side table We have called her 'Cucumber Rosemary' ever since AND wife saw her at work too but never said anything just smile to herself
