Sisterly Act
My elder sister who`s 29 yrs is married to an awesome guy, handsome & caring , I have been staying with them since they my only family and I get along very well with both of them, btw am 25 yrs, my sister is 25 weeks pregnant , couple of weeks ago her husband and I were having rounds of beer and he confessed to me that my sister`s doctor has asked him to refrain from having sex { my sis has some complications } , he said he loves my sister very much but the depravity of sex is killing him , he said he`s tempted to hire services of escorts, in the past her husband had never ever been hitting on me sexually or been suggestive or tried to get in my pants
I myself was going through a dry spell for more than a year, I gave a thought, if this guy goes whoring he`s surely gonna catch STD`s plus other complications , the best would be me letting him have sex with me, I opened my legs for him with a condition that after the baby we will completely stop having sex, he agreed and promised to adhere
From that evening we regularly having sex and loving it
My twin sister gave me two blow jobs to practice before giving her boyfriend one. I convinced her to swallow for the second one... Your welcome Danny..lol. That to say years later, both single, I asked for some help... Blow jobs started up and that led to sex... We are pretty regularly fuck buddies now. She's actually pretty submissive and a lot of fun.
After my hot older sister's divorce, she wasn't up for dating or meeting new guys, but, still had needs. Was at her apartment one night, just hanging after she made us dinner, and she went to her bedroom to change. Into her thin, short, and, left open robe. Standing in front of me, in the living room, she talked about needs and how we've messed around before, and "if you want me, come get me". I rose to my feet, approached her, separated the robe, and we started up a bit.
Getting into it, she leaned in and only said "Now", and I knew what she meant. We ended up in her bedroom the rest of the night, and, for the better part of a year, continued having sex 2-3 days per week. I was like her automatic FWB, her ready-made boyfriend (I'd sometimes take us out for dinner, and pay), and benefitted like crazy. Only her one downstairs neighbor asked who I was, once. Guy thought I was her "new man" and going to move in, since I spent so much time there.
That's very nice of you to do that for your sister. Plus you get to be pleasured so it sounds like a win win.
