I assisted my stepbrother after he got hurt at the fitness center

After a grueling gym session, my stepbrother injured himself. I rushed over to help and found myself unexpectedly giving him a blowjob. His big ass teen cock was too much for me, but I persevered. He reciprocated by taking me in missionary, then doggystyle. The climax was a hot load in my mouth, a thrilling end to our wild encounter.
