If you want a little boost in the size department to drive your partner wild, but a hollow strap-on is going a bit too far, why not consider a Cyberskin Transformer Penis Extension? This vibrating model adds 2 inches (5cm) of length and up to 1cm of girth to your beloved penis and is designed to be worn during your regular intercourse (whatever that may be).
Made from Cyberskin for an extra-real feel, this extension has a firm tip with a pocket for the tiny little micro-vibe that's powered by 2 x LR1130 (included) and runs extremely well for its size and considering it's encased inside the sleeve tip.
The sleeve itself is about 7mm thick when relaxed, but stretches (and thins) to about 5mm thick all-round on your average sized penis (it may be thinner for you, depending on your penis size). It can accommodate almost any penis, provided you're over 2.5cm wide and no longer than 14cm. It will also desensitise you against all but the buzz of the included micro-vibe, which can help overly sensitive men last longer.
The Transformer Extension can be trimmed with sharp scissors for a perfectly tailored and snug fit with no excess.
