Just as I started to undress to follow her command, I heard from the bed, “I’m waiting...” I quickened my pace and as soon as I pulled that soft..., sexy material against my rock hard cock, I nearly finished right there. It felt so sexy. I emerged to a big smile on her face asking what she though, posing a little of course. She said they were perfect and that I was right about sexy things not being made for me, but she was willing to share. Also noting that my rock hard cock oozing with precum. He looked so sexy, lying back on his bed in just his jeans, blindfolded. He wasn’t muscled up, but had a beautiful flat stomach and cute browny-pink nipples. His pale skin made him look incredibly beautiful.I undressed, down to just my panties. He had never even touched my boobs through my shirt before, so this was a big jump in the physicality of our relationship.I straddled him. ”Touch wherever you want,” I declared grandly.His hands wandered to my stomach. ”Not THERE,” I howled. Next day morning when my sister came to my room she was shocked, there was a porn running on my pc and she was watching it hesitantly, i was in my toilet watching her through a small hole after sometime i flushed my toilet, by hearing this she kept the coffee and went away.I came out drink coffee and went to kitchen to see how she will react, but she was like normal like nothing happened, so i opened the topic, and asked her have u seen the show on my pc morning when you came to my room, she. . really hard." Seriously? Why, Mom?" I don't know, Honey. One night years ago, your dad just started biting my nipple and I just loved it. I swear i couldn't get to bite hard enough. Since then I've done a lot of playing around with them." So, you mean, biting like this?"She took one of my nipples between her teeth and ground back and forth gently."That's kind of nice, Honey. And whatever you do will be awesome for me. But I really like them to be bitten pretty hard." Like this?" she asked.
