Seriously can't pass this up. -Kohai's passionate sex won't stop until morning

"If you show me this cute side of you... I can't control myself." So intense... It's too much...!! Yukako, a 30ish year old office worker who is perfect at her job and private life, isn't able to rely on someone else. But only her Kohai, Kotaro, respects her and accepts her as she is. For some reason, the direct words and actions of Kotaro makes her overcome with emotion... After getting drunk at a company party, she pushes over Shotaro who had taken her home--!? "I'm really going to do it...?" With a manly expression, he sucks strongly on her lips, and there's heat from his fingertips that move up and down beneath her underwear... "Still... Not enough." Never been wanted like this before... What should I do--!?
