"Is this the one?" "Yes it is. Thank you." "Well, we also have another in the same color and general style that would be a little better for the ball ...if you would like to look at it." "Sure, why not? But is it much more expensive?" "About $15." "In that case lead the way." She held up the same dress but had a little lace and glitter on it, not much, but it looked sexier. He gazed at it a minute and nodded. "Yeah, your right, that would be a little better. I'll take it. And if she doesn't like. Lisa kissed us both on the lips and apologized for running late, she picked up her drink that Sarah had bought and took a sip."Now what have you been doing with yourself? we haven't seen you for ages".We chatted, old stories were retold, it was like the old days when we younger and with nothing to worry about except getting drunk and getting laid.I was so happy, drinks with good company and a furtive grope on the way back from having a pee, I had already had more to drink than normal and was. I was in ecstasy fucking my step-mum and so was she. Her voice went very high pitched when I made her cum.Not sure how many minutes passed before she told me to stop and lay on the floor. When I was there, she instantly was crawling on top of me, rubbing her tits up my legs and my cock. She slapped it off them a few times, rubbing the head against her nipples before she sat up and started riding me. I felt my cock going in even further now, as she bounced faster. I spanked her ass a few times. I was rather disappointed to see that she was made out of fiberglass. Although her body was flesh tone, her breasts were hard and rigid. I don't know what I was thinking.I dressed her up in a pair of short shorts and a halter top. I tried arranging the light, to show her at her best advantage. I finally hit the combination that highlighted her features and made her look rather presentable. I watched her for awhile and realized that she was just a statue and she would always be only that. After.
