The bed started to bang against the wall, and she was almost screaming, there was no way on earth her mum couldn't have not known what we was doing. A...s I was pounding my cock into Karen's gorgeous pussy, I felt my balls tighten, and I knew I was going to cum. Karen could also sense this, and yet again today she shocked me with a pleasant surprise when she said "come on baby, fill me up, let me feel your cum shoot deep inside me baby". That was it I couldn't hold out any longer, and I felt spurt. She started her fucking slowly by drawing almost all the way out of me. Very gradually she began picking up speed. Over the course of a couple minutes, she worked her way up to a respectable fucking tempo and just settled in there. Her hands were on my knees pushing them back into my chest as far as she could. She was leaning her weight on me as much as she could while she was fucking me. The sight of my sister fucking my ass with a strap-on was absolutely the hottest fucking thing I had ever. ...I won't let anything bad happen to you ok?"I nodded nervously.Linda slipped out of her dress, to reveal Black lingerie, and stockings all similar to mine. She lay back and Mike took my shoulders and lay me back also.We lay at oposite ends of the settee, like sardines in a tin. Our stocking clad legs entwined, the feel of which always delighted me. I closed my eyes as Mike removed my panties and playfully squeezed my cock through its leather harness.He lubed us. first my ass and then Linda's. " Used to sleep out on the trap line, sometimes," Jim said. "Didn't have two sleds to haul all the stuff, either. Didn't even take me a tent. Just curled up in the sleeping bag in the sled basket, and threw the tarp over me. Dug me a snow cave, sometimes when they'd been a lot of snow." Doesn't seem that comfortable," Mike commented."I went though a hell of a lot worse when I was in Italy with Battery D," Jim said. "Did get a mite wet and cold at times, there."Eventually, they got the sleds.
