My girlfriend insists on using a condom! She absolutely won't have unprotected sex with me unless we're considering marriage, which seems so far off! Marriage!! Her sister, who is desperate for raw sex, has been tempting me with her big breasts and the promise of unprotected sex! I like my girlfriend, but it's impossible to resist her sister's soft breasts even through clothes! I took every opportunity to have sex with her sister! Eventually, my girlfriend found out... but it felt so good that I ended up ejaculating inside her in large amounts!
