A few mins later she comes bk with some cloths, jeans a black shirt she gives me a kiss and whispers in my ear "hmmm i love ur hard cock we will have ...un later but now get dressed and we will meet a mate of mine shes dieing to meet you to"she walks out the room to her room i get dressed as quick as i can i wanna try and see her change to my heart is racing so much i think it might just jump out i want her mouth around my cock again.after a while i am dressed i hear her walking towards me. Make my pussy cream for it!" She screamed.I sat behind her and positioned the dildo on the bench. I rubbed her pussy lips with it and she groaned. I pushed the tip of the dildo into her pussy. She rotated her hips on the head of the dildo and then tried to push down. Unfortunately, with her hands tied, she really couldn't move all that much. I pushed some more of the cock into her. I looked at her face in the mirror. She was the vision of concentration. Her brow furrowed, her lips curled and. Of course, the subject matter had something to do with it, but it was so smooth and sensual in my hands, I almost felt like I was molding her flesh between my fingers. As it is with most of my working sessions, I became engrossed in my work, so I never heard her come in. It wasn’t until I felt her naked body against me, her hot breath on my shoulder,that I knew. ‘Oh my god Jenn, you scared me to death.’ ‘Are you accustomed to allowing naked women sneak up on you like that?’ ‘Only a select few,’. She smiled and thanked me for my help. When she got them off she grabbed the waistband of my underwear and pulled them down too exposing my hard-on.Cherry said, “Okay girls, remember the rules? His cock has to go in your mouth before it goes in your pussy and then someone has to lick it clean afterwards.”Then Cherry slipped her mouth over my cock. All I could think of was that it was going in her pussy next and that I would loose my virginity. I was pretty sure that my sister was a virgin.
