Which is Ballbra. As in bra for the balls (and is it us, or has this unnerwear model got a bit of a gut?)
Anyways, what it is is… a pantie, which features an ‘exclusive hi-tech’ pouch (how hi-tech can a pouch be? Is there wiring and circuitry in it?) which, by day (’cause underwear has different functions according to the time, right?) provides unrivalled ‘lift, support and comfort’ to the general penage area.
By night – like Jekyll and Hyde – it’s a whole nother story…
Oh, yes, by night, the elasticated hi-tech pouch bit ‘cradles’ the testicles (aka ‘balls’) to intensify orgasms. We’re assuming in much the same way as a hi-tech cock ring. But we may be wrong as we have not had our scientists put the ‘hi-tech’ness of it all under the microscope.
Not only that, they also come in black. From here.
