ATID-677 | "The condom broke, so you have to take responsibility!" After a drunken night with a coworker, what was supposed to be a one-night stand somehow turned into her becoming my girlfriend... Misono Waka

Kazumi and I are colleagues, and we're both in relationships.
...But we got drunk and before we knew it, we were in a hotel.
Kazumi's sleeping face was defenseless, something I never see at work.
Fueled by alcohol, we gave in to our instincts and had sex over and over until morning.
"Hey, the condom broke..." "What!?"
I don't know how many times I'd ejaculated. Kazumi's voice made my blood run cold.
But I told myself it would be okay because I'd ejaculated so many times and my sperm was diluted.
We went to work as if nothing had happened. ...It should have been just like always.
But then Kazumi said to me, "Hey, will you take responsibility?"
...And so, what was supposed to be a one-night stand turned into a relationship,
and we cheated on each other again and again...
