My girlfriend insists on using condoms and no internal ejaculation! Her sister, however, is okay with internal ejaculation! And she has huge breasts! While visiting her house, I was seduced by her sister and secretly had sex! When she said 'It's okay to ejaculate inside♪', I couldn't hold back! The thrill of possibly being caught by my girlfriend, combined with the pleasure of internal ejaculation sex that I usually can't do, gradually drew me in... In the end, I ejaculated a huge amount in front of her!
