My girlfriend begged me to watch while her secret admirer took her from behind while I jerked off

In the dimly lit room, a stranger expertly slides his hands over the girlfriend’s curves as she lies back on the couch. Her boyfriend watches intently, his breath growing heavier with each languid touch. The stranger’s fingers trace her lips before moving down to tease her nipples through her thin blouse. She squirms with pleasure, her eyes fluttering closed as he unbuttons her top and exposes her firm breasts. He takes one nipple into his mouth, sucking softly while one hand drifts under her skirt. Her boyfriend shifts closer, his eyes locked on the scene as his own desire builds. The stranger’s fingers find her moist center, stroking her gently while his other hand grips her thigh, holding her in place as he pleasures her. The girlfriend moans softly, her hips arching against his skilled touch, ready for more.
