My boyfriend abstained from sex for 30 days, but I slept with his busty girlfriend first! (Hitomi PPPD-745)

After a month of abstinence with his girlfriend, the anticipated 31st day arrived, only to find he had to go on a business trip! His O-cup girlfriend was already in a beastly state with a 120% sex drive! He had no choice but to ask a trusted friend to take care of her… but unexpectedly, he ended up sleeping with her!
