Continued from Part 1 ... First day of our weekend visit was mainly chat between us all and a walk out with the children. When Tom and I were away from the girls, he would brag about his past conquests before his marriage and how his large member was a draw to the ladies he had been with. Since the birth of his last child his partner had gone off sex and he wasn't getting any attention at home. The odd innuendo was mentioned towards Sue and I went along with his banter knowing he was edging to see if Sue may be up for some fun. I brushed the conversation towards another subject but inside my heart skipped a beat and I knew he was up for some extra marital fun given the chance. The thought of his large cock riding Sue was coming to near reality and I was excited about the possibility of it happening very soon. Nothing more was said until later and I could see Tom was giving Sue lots of attention and could not take his eyes off her. The kids had all been put to bed and it was getting late when Toms wife announced she was off to bed. Her youngest often got up in the early hours so she was forever tired. A bit later Sue and I decided to retire to our bed, Leaving Tom downstairs. After washing and getting into bed i told her Tom had told me he wasn't getting any sex at the moment and hadn't had any for a while. I told her he had shown interest in her which she confirmed and said Tom had caught her earlier on in the evening at the kitchen sink and had pushed into her behind whilst reaching past her for a mug. She could feel his hard cock pushing into her bottom and feel his breath on her neck before moving off again I asked her how she felt and she admitted she wished he had pulled her pants down there and then and pushed inside her. I was about to suggest she go back down stairs but she beat me to it and said she would go back down if ok with me to see if Tom was still up. My heart was beating ten to the dozen and without a thought I said go for it and felt between her legs to find she still had a pair of panties on and they were wet with anticipation, I said you are ready by the feel of your pants, you better go before he comes up stairs. She slipped out of bed and i realised it may happen sooner that I anticipated and was too late to change my mind on allowing her to go . She slipped on her nightgown, pulled off her pants and threw them at me and said,put these on until I return. I slipped on her wet pants and wondered what, if anything would happen as I lay there rock hard and reality hit me that she was gone and may be about to have sex with someone else. Shall I wank and cum, if i do, will I be able to get hard again when she comes back up. What a dilemma. I lay there with a pounding heart wondering what was happening down stairs. I couldn't hear anything as hard as I tried and just had to lay there and fantasize waiting and waiting, not daring to touch myself in case I shot my load which was a certainty. Time goes really slowly when you are waiting, many things went through my mind and the possible consequences of allowing Sue to fuck someone else. I was the only partner she had and had known her from schooldays. I imagined her being like a kid in a sweet shop for the first time, ready to sample all the sweets. Time went on, she returned very quietly in the early hours and as she opened the bedroom door to enter I asked if she was ok. I was trembling as she slid into bed and said, You have been a long time. She sighed and said, It was wonderful. Did he fuck you, I asked. Of course, she said, It was so big and hard, just wonderful, indescribable. I felt between her legs and found she was sopping wet with his cum, I could feel her lips were swollen and puffy and was obvious she had been well fucked. My fingers slipped inside easily and squelched with the juices. I wanted to fuck her there and then but she said she was too sore as she had been fucked several times in different positions. She wanked me and started to tell me what had happened, I started to remove her pants but she stopped me and told me to keep them on as she knew I like to wear them They had kissed at first, then he took off her nightgown and looked at her naked body and started kissing her body from neck downwards. He removed his clothes and she got her fist glimpse of his hard cock saying she was amazed how much bigger than mine it was. She took it in her hands and wanked him, kneeling in front of him seated on the settee and took it into her mouth savouring her first taste of a cock other than mine. She sucked and slurped on it for some time as he pulled her nipples making her cum for the first time. He held her head and pulled her onto his cock making her gasp for breath and gag on it but she loved it and kept going until she felt it twitch and he tensed up hold her head tight and fed his cum into the back of her throat. She swallowed it all and licked him clean, As I kissed her I could taste him on her breath, so nice, a first for me also My cock was bursting but because she said she was sore I went down the bed between her legs and licked all the cum and juice that was leaking out. She shuddered as I made her cum and then went on to say she thought that would be it but Tom pushed her onto the settee and went down on her, licking her out, darting his tongue inside her slit, She said she was in heaven and came several times, She wrapped her legs around his head and pulled him into her keeping him there until her legs were tired. She described his tongue as wonderful and didn't want it to end but all good things end but got better as he slid up her body and entered her with his rock hard cock. He pushed all the way up making her gasp. then pulled out and pushed his cock head in and out teasing her She was in sexual heaven and said he did her in several positions but was difficult to make love without making a noise as she wanted to scream out in ecstasy At this point, I was bursting and shot my load over her puffy lips and was suddenly satisfied and brought down to earth into reality realising what had happened.
