I would have to say that I am a fan a larger boobies (NOT the grotesque sizes like G and up!), but I have to also say that it depends on the lady and her build. On some an A or B look wwwwaaayyyy better than a C or D cup would.
Now, have to say that the new enhancements Samantha Jaymes has been showing off do make my mouth water. Looking forward to her recovery being over and giving those newly enhanced boobies a proper workout!
