Once inside the shed three sets of eyes saw the set up. I figured it was time to break the ice, undid Mary's blouse, took it her bra & shorts off, lea...ing her wearing only a smile. Sorry boys, it's your birthday, but I unwrapped your gift. They again looked at each other, me, then Mary. Mary started undressing them as their hands found her body & began to examine it.They eased her onto a mattress, each taking a tit into their mouth, Will started fingering her pussy, as Paul began kissing her.. Finally, with a push, he entered her vagina once again and kept it inside for a while. Then with some force, he started fucking mom’s pussy. After 2 mins she stopped crying and started moaning again. Grandpa cut through all such pretentious bullshit. Now, mom was more comfortably supporting grandpa’s rhythm. He continuously smelled and kissed mom’s back while her bare boobs kept jumping with impact. This continued for about 5 more minutes and finally, he again gave a loud moan keeping his dick. Did I want to join in? Yes I did, but I didn't and I can't even give a clear reason as to why I didn't.Seeing Karen naked was a turn on. Watching Karen suck cock was a turn on. Seeing Karen taking cocks in her pussy was a turn on and hearing her squeal as her ass was reamed was a turn on. That sexy body with one, two or three men in it was a turn on. Yes, three! She took Dave in her ass, Phil in her pussy and sucked Marv's cock all at the same time and my cock was so hard from watching that I. She didn't want to cum, she had been ordered not to.She pushed my head away from her cunt, but I looked up at her saying, "I want you to cum for me Jean. I want to taste you as you cum."She looked down at me, her breasts rising and falling with her labored breathing. Her face red, she watched me as she pulled my face back to her clit. She watched me until she exploded in orgasm, crying my name as she came.We lay very still for a long time, my face resting on her thigh, as she slowly calmed.
