From: http://www.nydailynews.com/news/cri...tion-sex-best-friend-son-15-article-1.1776438 Woman, 43, sentenced to probation for having sex with best friendâ€™s son, 15 Karen Lee Carstens began the abuse with touching the boy in 2007 at his Texas home when he was 13. It progressed to several sexual encounters while her best friend, and the boy's mother, was hospitalized. A former Texas woman convicted of sexually assaulting her best friendâ€™s son for years, beginning when the boy was only 13 years old, was sentenced to five years of probation Thursday. Karen Lee Carstens, 43, started with touching the boy in 2007 before the relationship progressed to oral, vaginal and anal sex, according to court documents. The boy told police things got really serious while his mother was in the hospital with a gallbladder infection and Carstens was tasked with watching him, KHOU-TV reported. In May 2009, the two had sex on a sofa bed while watching TV. The boy told investigators he cried afterwards because he worried heâ€™d impregnated the woman. She told him not to worry because she knew her menstrual cycle. Another time the boyâ€™s mother was hospitalized, in June of that same year, the two were amourous in the boyâ€™s bedroom. Worried about impregnating Carstens, he asked her for anal sex. She at first declined before agreeing to his request, the Houston Press reported. The woman, once of Spring, Texas, moved out of state to Riva, Md., in 2009, ending the relationship. She told the boy to keep it a secret because she would â€œget in trouble,â€ according to KHOU. She was held on $30,000 bail after her arrest and found guilty in a several-day trial last week, wrapping up Wednesday. â€œI feel like she deserved everything she got, so Iâ€™ll leave it at that,â€ the victim, now 19, told KHOU after the trial.
