Ben looked through Dave's sister's wardrobe and lingerie drawer and threw some things on her bed. Dave's sister is in her twenties and very hot (her n...ame is Bianca by the way). She is always wearing sexy clothes when we see her out. I was then told to put the clothes, which were on the bed, on! I protested but this was now my dare and I didn't want anyone else knowing what Ben and Dave already did about my fetish.I started to get dressed in Bianca's sexy clothes, which were laid out in front of. As she's rubbing my pussy and it feels really good. My mind is gone. I could not say anything because I was just getting over crying so hard about Jeff. I just let her do whatever she wanted to do. And it felt really so good I just didn't care. This went on for some time and then she pulled my nightie up and put her fingers directly on my pussy area. It felt amazing. She pressed a little harder until her fingers were slightly inside me rubbing up and down against my clit. I couldn't. Luckily I was only relatively young so keeping hard and carrying on fucking wasn’t a problem I could cum three or four times in one session, (where have those times gone, lol). I pulled my cock out of Pams hole, my spunk was oozing out and her labia was coated in both our juices. I beckoned Steve to change places with me. I knelt in front of Pam, leant forward and spread her arse cheeks wide as her lips closed around my spunk covered cock and watched with excitement as Steve slid his saliva. I prided my eyes away trying not to be caught with my bonner. So I dashed to the kitchen. Only to be caught off gaurd, I saw mom squirting breast milk in a empty jug. She looked up and saw me standing there with my cock hanging out. "Tommy come closer please." Mom said touching her tounge to her lips. Her eyes drifted down to my cock. I slowly aproched my mom trying hard not to stare at her d-cup breast. They got this size when my sis was born. And in a way I was jelous that sis got to touch.
