One day during overtime, I couldn't go home due to a heavy downpour and Karen-senpai offered to let me stay. Alone with her, seeing her wet, see-through body up close made my reason crumble! Even though I have a girlfriend... but the incredibly erotic body of the senpai I've always admired! There's no way I could resist such temptation! I just want to cum, no matter what! I greedily indulged in her soft, large breasts, having sex multiple times until morning, releasing inside her in the living room, in the bath. Ignoring calls from my girlfriend, we kept going at it until right before work. A record of our two forbidden sexual escapades...
