In the dimly lit room, the 18-year-old teen boy, his cock already stiff, hears his roommate's soft moans from the other bed. Tiptoeing over, he peeks to find the 19-year-old, still in his pajamas, stroking his length. The younger boy, intrigued and aroused, whispers, "Can I join you?" They masturbate side by side, their eyes locked, hands moving in sync, feeling the taboo thrill of their shared bisexual awakening.
