UD-548R - I was written off by a relative, an aunt.

One day during summer vacation, a relative's aunt came to visit from far away. I was a first year student at ○ School and was home alone due to my parents' urgent business. A frustrated lady came into my room and seduced me by showing me her cleavage. I grabbed my son who had grown bigger and took him into my mouth. The woman's unruly behavior doesn't stop and she ends up playing with her virgin nephew who has no experience! !
