My Mrs used to live with a guy,houseshare only many years ago. They have stayed in touch and text /ring each other all the time. I get on ok with him too and have spoken to him a few times. He is very skinny with glasses and not much to look at but she has known him for years and he makes her laugh a lot so they have stayed friends. She hasnt to my knowledge met up with him in ages but called me recently to say he had showed up at her shop and wanted to go for a drink after she finished. She asked me if i could join them but i declined as i had other things to do. She came in about nine thirty and had obviously had a bit to drink. She said they had a good laugh and i thought no more about it. A few days later i had to look up a number on her phone,it was late and she had gone to bed early so i helped myself. After finding the number something made me check her recent texts. Amongst others was a couple from Russ saying how much he had enjoyed their fun together and how he wanted more?! More what? He said he would love to stay overnight and thanked her for the invite. What invite? Nothing was mentioned for a few days, then she casually dropped in to the conversation that good old Russ had asked her if he could stay over for one night as he was working locally and would love us all to meet up again. Hmmmm. I agreed he should stay the night. He arrived Saturday and i was gardening,she was at work. We chatted and shared some wine. Near to five o'clock he said he would wander down to meet my Mrs from work. They came home about six thirty having stopped for a few drinks and a take away. More drinks were consumed during the evening until after midnight, tired, i said i was going up. She followed but he said he was going to watch a late film and turn in later. It was about four o'clock when i woke up and noticed she wasnt there. I snuck downstairs quietly and peered around the stairwell in to the living room. The sight before me gave me an instant hard on. She was on her back on the floor,her white silky slip pulled up,one strap pulled down. Her pussy was exposed and one breast. He was kneeling beside her in just boxer shorts. They were pulled down exposing a large rigid cock. It looked bigger than mine and perhaps thicker but the contrast of this thing against such a skinny guy was strange to see. He had a hand between her open legs and was fingering her whilst she held his cock. He shuffled forwards and she raised herself a little on one elbow. She guided his cock in to her open mouth. She was struggling to hold it downwards as it was very erect. Her mouth slid up and down over it and he softly stroked her hair. This seemed to go on for an age but then he withdrew and got between her legs. In one movement he rammed it straight up her making her whimper and grunt. He fucked her hard, fast and without stopping for what must have been a good fifteen minutes. I could see his cock withdrawing fully and slamming back up her, making squelching noises. His balls jangling about. His stamina was truly impressive. She held her legs wide open and he gripped her arse cheeks and sucked her revealed breast. They snogged and i saw her biting his neck and gripping his back. She had cum at least once from what i could make out but he hadnt seemed to yet. He stopped suddenly and said something to her. He slid out, resumed his kneeling position and she moved towards his wet cock. With me she wont suck my cock after i have fucked her, saying she doesnt like to taste herself on me. She showed no signs of disgust with him though and swallowed it straight down then procceeded to suck him. Her hand cupped his balls. He slid the remaining strap from her shoulder to free fully both her breasts. Within seconds i heard him say something about cumming. He groaned and was obviously empying himself in to her mouth and down her throat, he held her head firmly. His cock must have been right down her throat and she seemed to be struggling as he held her head. It must have been a good minute before he let her go and it slipped free. She gasped loudly and panted for air. He let her recover for about twenty seconds only before holding her and shoving it back inside her mouth. Holding her shoulders and gripping her hair he started to face fuck her. She steadied herself and amazingly let him do it. I could see she had reached between her legs with one hand and was playing with herself. After a couple of minutes he groaned again and slipped it from her mouth. Holding her chin with her mouth open he shot his sperm in to her mouth. He then slid it back in and down her throat firmly. He held her long blonde hair tightly and she soon started to wriggle. He slipped out of her mouth and slumped to the floor leaving her gasping again. As she lay back i saw she had two fingers still embedded deep inside her pussy. I had never seen her so submissive. Although she had clearly almost choked on his cock she seemed to have really got off on it. As i watched she squirmed and writhed. She pumped her fingers deep and hard into her pussy very quickly then went rigid and with them still inside her she came heavily. I left her kissing his wet groin as they lay together and i returned to bed. A blow job from my Mrs is normally an occasional thing and quite slow and gentle. You think you know a persons likes and dislikes. The episode has aroused me to new levels. He is staying again in September and she has mentioned us all going away together.
