HUNTA-078 - My Best Friend's Girlfriend Came Back to Beg for My D

Honestly, I can't keep up with the plot. Somehow I end up sleeping with my friend's girlfriend, somehow the condom comes off halfway through without her noticing, and by the time the first round is over, she's turned into a nymphomaniac. The girls are all cute. It seems like this series ended with this installment, but I'm hoping for a sequel.
