To your room

Your room is nearer which makes it a logical choice. There's also another reason which is you don't want to do her on the same bed she and your father have sex. You push Rumi to the bed and begin kissing her. While not resisting, Rumi doesn't really respond actively to your kisses.

You stuck your tongue inside her mouth, forcing it to open a bit so that you can french kiss her.

You lick the light pink nipples of her small, perky breasts, eliciting an unwilling gasp from her. She closes her legs around you and gently put her fingers through your hair as you feast yourself on her body.

Eventually you've worked yourself enough to not deny the act anymore and positions your manhood at her entrance. This causes her to raise her eyebrows. "Wait," she says softly.

"What is it?" you answer despite not wanting to wait anymore to be inside her.

"Around this time, I'm fertile," she says. "If you don't have any, there are some condoms in the main bedroom,"
