[F18] I gave my cousin a handjob

I was 18 and staying at my aunt's house for the summer when my cousin, Mike, who was 25 years old, walked in on me touching myself in my room. I was so embarrassed, but then I noticed the bulge in his pants. I took off my shirt, revealing my bra. Mike stared at me with shock but i knew he was into me.. I walked over to him and whispered, "Do you like what you see?" He nodded, barely able to speak. I leaned in and kissed him softly on the lips. As we made out, I heard my aunt and uncle return home. 

I quickly pulled Mike into the bathroom and locked the door. I pushed him down and started giving him a handjob, stroking his hard cock. He moaned with pleasure, his eyes rolling back in his head. As I felt him getting close to orgasm, I heard my aunt's footsteps coming up the stairs. I quickly dried him off, then unlocked the door just as my aunt knocked. I opened the door, trying to act casual as Mike hid behind me. My aunt looked at us suspiciously, but I just smiled and told her I was helping Mike find his toothbrush

As soon as she left, I pushed Mike back into the bathroom and finished him off with my hand, he screamed so loudly and his cock twitched as he came for me... he called me "mommy" after i felt so good about myself.. I made him promise not to tell anyone what happened, and he obeyed like the good boy he is.., knowing that he's my property... i really want to get some lube and give him a footjob next he's so submissive and i saw him staring at my feet...
