I'm looking for 2 h-manga which titles I forgot. 1st one:

The first one involves a man marrying a student. Everytime they have sex, the neighbor next door, the student't teacher, will be envious. The next chapter involves the student waiting for the husband to return. The husband was brought back by his manager, drunk. As they both carried the husband to the room, the manager saw a dildo on the bed, and thought the student was trying to seduce him. Sex happens.

Next day, the student takes the bus to school, and met her ex-bf on the train. Sex happens. There are a few more chapters after this but I don't seem to remember it all too well.

2nd:

I'm giving them imaginary names. These names are not real. John and his girlfriend, Jane, goes to the pool. Jane brought her best friend, Tina, and John brought his best friend, Tim. John and Jane wants to hook Tina and Tim up. As they sat down, Tina started seducing John, even going as far as to giving him a leg job. They soon entered the pool, and John and Tina got it going. Jane said she'll go off with Tim to buy some drinks. While John and Tina enjoyed their time together, Jane was going on with Tim. One quote I remember from this manga was this. "So Jane, you do this for John all the time?" said Tim. Jane replies, "No, he isn't as perverted as you." or something on that line. Please help me guys!
