Naomi was a virgin too , hence for her to bend over and invite Rudra was a big step for herself as well . Even then she was more than happy to do it as the one to pop her cherry was Rudra.
Rudra was in a dilemma at this moment as looking at Naomi soo vulnerable he found his resolve weakening as a man as he soo wanted to taste the warmth of a woman for the very first time. However , even though Ruby was a fictional character she was also in a sort of relationship with Rudra hence why the hesitation in Rudra's mind on wether or not this was the right thing to Do.
Rudra understood that he had a strong attraction for Naomi as well and that he wanted her really bad , but he knew that if he did not come clean before doing the deed then he was a scum of a man , which he was not ready to do.
Hence even in the heat of the moment and his hard dick screaming to him to do otherwise , Rudra said " We need to talk first... ".
