Two brothers, bound by blood and boredom, find themselves alone and horny. They start by jacking off, each in their own room, but the thin walls can't contain their moans. Soon, they're masturbating together, sharing their fantasies. One brother, hung like a horse, can't help but imagine his sibling's tight ass. The other, equally endowed, dreams of his brother's eager mouth. They edge each other, pushing their limits, until they can't take it anymore and explode in a mess of cum and relieved sighs.
