First one is "First Impression 天海つばさ" - IPTD-500
Second one is "つばさ先生の誘惑授業 天海つばさ" - IPTD-593
つばさ先生の誘惑授業 roughly translates
(coz my 日本語 is shit!) into "Tsubasa-sensei no yuwaku jyugyo" or "Tsubasa teacher seduction class".
The actress in both is 天海つばさ or
Amami Tsubasa.
I've attached torrents to both but I have no idea if they're still being seeded.
