Mei Mei invited you over, telling you that she wanted to study. She's been friends with you ever since the 5th grade; when she came to the USA, you were the first person to want to help her and show her around the place. Ever since then, you too have been the best of friends.

Mei Mei opens the door, inviting you in. "What's up Rubii! Thank you so much for coming over!" She gives a warm hug. You feel her huge breasts press against you, making you blush slightly

It's currently Friday, and her parents won't be back until Monday.
