STCVS-017 Two office pairs cross the line after overtime and on a business trip

The first pair are colleagues who clash at work but had sex one morning after drinking and cannot forget it. Alone during overtime, their bodies touch and they go at it again. The second pair are also colleagues who argue constantly; on a business trip a reservation mix-up leaves them one room. She teases him with her underwear, he responds, and they end up in bed.
