The gloryhole's curtain rustles as a big, black cock pushes through, seeking release. A hungry mouth envelops it, slurping and sucking, while a hand jerks the thick shaft. The cock-owner moans, pushing deeper, fucking the mouth. They switch places, the cock-sucker presenting his ass. The black cock spears his hole, raw and bare, fucking him hard and deep. The cock-sucker jerks his own dick, cumming all over the gloryhole's wall. The fucking intensifies, the cock-owner pulling out to cum in the mouth, ass to mouth, before trading places again for another round of hungry cocksucking.
