I don't understand what it is that makes me want to dress in her lingerie, but the urge is very strong at times.

My wife is curvy. She has large breasts and wears size 14 clothes. This is helpful because it means I can (just about) squeeze into them without stretching and ruining her underwear.

She knows about my fetish and sometimes indulges me but I seem to have a high libido at the moment and I'm keen to get dressed up again soon.
