Watching Her Boyfriend Shower

Des Irez had recently completed his usual morning routine and exited the bathroom, only to accidentally run into his elder sibling's lover, Lucca Mazzi, who was clad in nothing but a skimpy undergarment and a tank top. While conversing, they discovered that Lucca had spent the night, with the sibling already gone for work. Despite Lucca’s confident and masculine demeanor, Des was more reserved and bashful in their chats.
It became apparent that Des had developed feelings for Lucca, little by little. Eventually, Lucca strode into the bathroom, undressed for a shower, while Des left the room. After a while, Des surreptitiously peeped through the slightly open bathroom door, craving a glimpse. Entranced by the sight of Lucca cleansing his fit physique, Des seized the moment.
Courageously, he sneaked in and picked up Lucca's discarded garment from the floor, indulging in its scent. Holding the jockstrap fueled Des' imagination, leading him to pleasuring himself right then and there. until Lucca unintentionally caught him in the act. Mortified, Des stammered out an apology, but surprisingly, Lucca was unperturbed.
To Des’ shock, Lucca shared that he was bisexual too and expressed his mutual attraction towards Des! With the freedom of an empty house.
