Blue-thong-clad bodybuilder, a vision of chiseled pecs and bulging biceps, indulges in a private, solo frottage session. His rock-hard abs glisten with sweat as he grinds his massive, veiny cock against the bedsheets, the friction through the thin fabric driving him wild. The tight blue thong accentuates his beefy thighs and quads, flexing and tensing with each thrust. He groans, his breath ragged, as he edges closer to release, the head of his cock peeking out from the thong's waistband, dripping pre-cum.
