This work features bright yellow-green competitive briefs that are notably small in size. Designed to fit snugly against Arrow-kun's smooth, navel-hair-free skin, the tight fabric enhances arousal simply by being worn. The briefs possess a strange, irresistible charm that makes you want to grab his cock, and as it gradually grows, gentle stroking causes it to bulge noticeably against the fabric. With the cock spilling out from the tight confines of the briefs, the wearer can rub and stimulate himself exactly as desired, intensifying pleasure to the fullest.
