One was about this god prince? who was kicked out by his dad to earth. the only chapters I can remember is one where he helps this athlete student regain her ability to run and jump by having sex with her. Another he helps two lesbians by having sex with one to turn him into a man so they(the lesbians) can be together. He has sex magic.
The other was more comical and was about a guy (college age) and a little devil girl(tsundere) and a childhood friend (girl). it had more than 20 chapters. i remember an angel character coming down, and later his future daughter. Some chapters took place in his college. Including some girl that had fantasies of being watched by her whole class.
Sorry that last one is vague its been a long time.
