I asked my sister if I could nurse on her breasts. She’s 19 and living back home with mom and me. I’m 17 and always h**** as hell. To my surprise she was all for it since her breasts were swollen and felt like they may explode with all the milk. The baby couldn’t keep up with what she produced and the pump hurt her to use. We had played Doctor when we were kids but that stopped when she got her first boy friend when she was 13. I wasn’t even making sperm yet but could o***** and do every thing she wanted me to do for her pleasure. And she would do the same to me. Oral and finger f****** and rubbing off mostly but we did bump uglys without to much penetration. After my niece and I finished suckling and kneading her breasts she put her down to nap and asked If I would like to play Doctor like we used to. I told her no. “I want to play a more grown up version.” We have been at it for the last 3 months and love it.
