My husband's nephew came to Tokyo and stayed with us for a week. He's a real bookworm, so he started studying hard as soon as he got home. His attitude made me want to seduce him, and although he ignored me at first, I managed to get him to erect (huge cock)! Then, while my husband was away on a business trip, I set up a reverse night visit and took his virginity... but my libido exploded after our first time having sex! I wasn't satisfied with just one time, so even though I ran out of condoms, I forced myself to have sex raw, and when Yumi tried to escape, I covered her and inserted my cock into her and repeatedly inseminated her!
