Five permanently horny friends, all in chastity for a month. Today is the big day when the full balls may be emptied. To make the whole thing more interesting, the five play spin the bottle. One by one, the clothes are taken off until the exciting moment arrives and one cage after the other may be unlocked. In the end, a locked sub remains and must dutifully provide the ass for all the others. After a long time, the cocks are rock hard and the balls are so blue that all holes of the bottom are filled while he has to stay locked and desperate.
