ルームメイトが私を誘惑して彼女とセックスする

For several days my roommate has been cleaning the apartment in a quite seductive way and every time we have a moment together she is in her underwear saying she is more comfortable... But on one occasion she comes into my room half naked and doesn't. I resist the urge to fuck her... The best of all is that she let me penetrate her without a condom and asked me to fill her vagina with semen!!!
