Wow, she was wearing low cut type blouse with a threaded knot at back and I checked it slowly with a stethoscope. Now I ask her to turn towards me and...I start checking her front part of the chest and I keep my steth on her breasts and it was difficult for me to hear sounds as she had 38 size breast inside tight blouse.So I asked her if she could loosen her blouse a bit or lift breast with her hand a bit. She was very happy to loosen the blouse actually and she untied the thread at the back. Their touch was now skin to skin. The feeling of his smooth chest rubbing against her breasts was orgasmic in and of itself she thought this was such a treat and just blushed from ear to ear. She had seen his cock all those years ago when they had fooled around in his bedroom but she yearned to see and get a better feel of him so, standing in only her knickers, she stepped back and simply began to admire his body. With her memory refreshed, his cock was how she remembered it but this time hed. “If you guys are going to start coming, I better stop talking and let you concentrate,” Fiona said, “but first, a few words of encouragement, for you, Wayne.” She leaned closer to me with a mischievous smile, and said, “Fuck that pussy, Wayne. Fuck it. Fuck your sister’s pussy. Work it baby, work it. Own it, baby,” giggling, “Go on, give it to her, big guy.” I kept up my fucking motion, trying not to be too distracted by the sexy little nutcase beside me, and as I felt myself getting closer. I kissed her soft thighs and the outer folds of her pussy before plunging my tongue back inside her, tasting once again the now familiar taste that was my step sister.Samantha let out a high pitched moan, a wonderful sound I hoped I would cause my step mom to make, as my tongue entered her and started snaking around, exploring the interior of her feminine part once more. I slowly reached my hand up her body until I found one of my sister's boobs and started fondling it, feeling her breast's.
