Now he looked at me, waiting I should do as I had been ordered.I felt the butterfly buzzing and the known heat it gave me every time I used it on my b...rning clit. He also put a finger over my mound, waiting for me.I closed my eyes and opened my red lips, to moan while the burning sensation was being built up in my cunt.Then suddenly it was there, that amazing dull ache, that crazy slow throb. As I felt it even deeper, making me gasp a bit and moan, I knew I was in trouble. Because that bastard. ''Wow, that's so cool. So, you really like my boobs then?' Sophie stuck her chest out as she asked.'Yes Soph, I think they're absolutely beautiful. Just like the rest of you. You're a total stunner. I mean it. I shouldn't say it but you're exactly the type of girl I go for. It's just a pity you're my sister and you're only 16 hahaha' I joked. I then thought how that wasn't much of a joke and that I was finding my sister's naked body very attractive.'Yeah, yeah.' Sophie replied.'No, c'mon, I'm. "Bathroom too. Uh, no tub I'm afraid, just a shower, but..." Let's take a look," she suggested playfully. "I hope it's a big bed." Yeah." I thought I had enough memories by then, but Stacy was already moving and I followed her like a lost puppy."Ohhh ... This is a nice bed." She sat on it and the bed wasn't large, just a twin mattress, but already made-up and comfortable enough."The bathroom is..." I gestured towards an open door."Hmmm..." Stacy sighed, laying back on the bed and bringing her. I then saw four feet under the stall door, and Peter did too. He shuffled to the side to give a view to the boys and me via that crack. I looked, and saw eyes peeking in and laughing. Peter kept fucking my face and this audience must have been more than he could handle as he said “Gonna cum in your mouth to lube it up for the rest of the guys Mary” as he began to cum in my mouth. “Swallow that cum slut” he ordered, which I did eagerly. Then he pulled out, unlocked the door, walked out and said.
