Our sex life was definitely more active though. We had started watching interracial porn during sex and her orgasms always came during the big money shots. I would fuck her with four well lubed fingers while she played with her clit and watched the video. One night I was watching her big ass writhe and buck to meet my hand, making me pump my hand harder. Just as the big black dick on the screen emptied it's load on the actress, I pushed my hand forward hard. I could feel her pussy widen as an orgasm began moving through her body. Her pussy opened and my entire hand was sucked in all the way to the wrist. She cried out as the orgasm built and started bucking her gaping pussy against my hand. I wanted a chance to really see how far I could push this, so I jumped at her Mom's offer to take the kids for a week in early summer. We dropped them off on a Saturday morning and drove the two hours back to our house. We had planned a romantic evening, with dinner and a few drinks. I had other plans too. After dinner we walked to the down town park on the way to the area with the college bars. I showed her the little present I had brought, a small bag of psychedelic mushrooms. At first she said no. I reminded her of all the fun we used to have with them and finally she said yes. We slowly nibbled the caps and smoked a joint watching the sun sink. It was dark by the time we made it to the row of bars. I was high from the joint and the wine at dinner, but I was just starting to feel the effects of the mushrooms. Little tracers let me know they were good. Really good. At the first bar we talked casually and had a few beers. The mushrooms were making me antsy and I readily agreed when Tami suggested we check out a different bar. We walked past several bars, some too bright, some too crowded before we finally came to Red's. More a cowboy bar than a college bar, but it was dark and quiet inside. We sat at a booth and drank Red Bull and vodka while we talked. We talked about everything you could imagine. Tami was more vibrant and animated than I had seen her in years. She talked with a loud voice and broad body language. It was a good time. I looked up from my drink and noticed that the bar was slowly filling up. There were some couples and a few bar flies, but most were men. I got up to use the restroom and when I came back I saw that Tami was not at the booth. After a second, I saw her standing at a nearby booth talking to a large cowboy type. He was lighting a cigarette dangling from her mouth. A few minutes later he was joined at the table by a large man in a mechanics shirt. She looked really hot, in a little back dress that barely held her big boobs in and a cigarette dangling from her mouth. When I walked up to the booth, she said "Oh! This is my husband. He is from Georgia too." Seems that the two guys were visiting workers from not too far from my home town. Their names were Chuck and Terry and they were mechanics of some sort. Like I said, Tami was on a roll. We stood by their booth for 10 minutes as she talked and talked. Terry, the fat one in the mechanics shirt, suggested that we could sit down. Before I could protest, Tami accepted. I spent most of the next forty five minutes wishing that we had stayed at our own table and talked. I was peaking on the mushrooms and feeling the effects of the redbull and vodka and it was quiet boring listening to Tami talk to to guys I had no interest in hearing her talk too. I was hoping to get Tami even more messed up and taking her to the adult book store, but she was only interested in chattering on and on. She asked them about their families. She asked them about their homes, their jobs and everything else you could think of. Eventually I quit listening and started watching the dance floor. I must have passed out for a few minutes, because Tami was shaking my shoulders saying "Hey, Chuck and Terry want to smoke some weed. Let's go outside." I felt the world sway under me as I stood up. I could tell Tami felt the same way from the way that she swerved through the crowed. Outside on the street their were tons of people. "We could walk over to the park" I suggested. "We are just staying right over there" Chuck pointed down the street "We can smoke there." They shared a small room at street level in one of those pay by the week type motels. I sank into a chair at the back of the room and started packing weed into my pipe. Tami sat on the bed next to Chuck and Terry sat on the other bed. I figured I could use it, so I packed an extra large bowl full and started passing it around. The more it went around, the quieter Tami got. She always gets quiet when she gets high. Tami lay back on the bed and mumbled something about trailers. I laughed lightly. I closed my eyes for a second and looked up to see the two workers were looking at Tami. Her slinky black dress had rode up on her heavy thighs. Her breathing was heavy and I wasn't sure if she had passed out or not. I closed my eyes again, but this time I stayed very aware. Two minutes passed when I heard Terry say "Looks like you better get your wife home. It's getting late, you don't want to let it get too late." I looked over at Tami and saw that her dress was even higher than it had been. "She's ok" I said "If she isn't bothering you." There was quiet and I closed my eyes again, letting my thought drift. Suddenly I became aware of a light moaning. I looked up to see that Tami was still passed out but Chuck had his hand on her pussy, rubbing it over her panties. Terry was on the other side of her, dry humping into her big hips. I knew that she would not be passed out for long, the two guys were going to wake her up. I knew how I would deal with it too. I got up from the chair and walked over to the bed. I bent over Chuck and pulled the dress strap off her shoulders, exposing her huge tits in the dim light. "There" I said "Get you some of that." Terry pounced on the opportunity by going straight for it. I saw him wrap his bearded mouth around my wife's huge nipple and suck. It seemed like time stood still as I saw her body react to the mouth on her nipple. A light moan escaped her lips. I bent down again, this time I pulled her panties off. I bent closely and watched as Chuck dipped a finger into her wet pussy. I saw it clearly as he rubbed the wet finger into her clit. I saw as her big ass bucked against his finger. I heard her say "What? What?" "Tami. I want to watch Chuck and Terry fuck you. I want you to lay there and let them do what they want. Do you understand?" She shook her head yes and closed her eyes. This was all the go ahead that the two men needed. Chuck began pushing his flinger against her clit while Terry pulled his hard penis out of his pants and dry humped her ass cheeks. After a few minutes, she started pushing back against Chuck's fingers. She was going to have an orgasm. When she came, I saw a flood of juices run around Chuck's fingers. The young cowboy type pulled down his pants to reveal a slender body and a good sized penis. Without any ceremony, he moved between her legs and sunk straight into her pussy. "God damn you got a gape of a pussy girl. Damn good pussy." For about 45 seconds he pumped into her fat juicy pussy before he started to cum. As he pulled out, I caught a glimpse of white cum stuck to her pussy. I was moved aside as Terry moved into position. I had not gotten a good look at his penis before, but man was it huge! Not really long, but as think as my wrist. I got behind him to watch as he lined up above Tami's pussy. I think that he was expecting more resitance, but my cock throbbed as I watched my wife's huge pussy open easily to accept him. She screamed out as an orgasm rumbled through her body, just from having the huge cock inside her. His fat belly hung over into her fat belly as he started pounding the massive cock into her pussy. "Lick my pussy!" She screamed. Tentatively, I leaned forward and started licking at the point where his dick entered her pussy. Slowly, he stopped thrusting deep into her and moved his cock toward my mouth. He quickly pushed it in and pulled it out. I looked at Tami's pussy and could see it was a gaping hole with cum clinging to the edges. He stuck his dick back in her pussy and pulled it out. The gape was amazing. Just then he rammed his cock into my mouth and pumped several times and then pulled his cock out and held it a few inches from Tami's upturned gaping pussy. He came in a spurt and a gush as steam after stream of cum went into Tami's gaping hole. I instinclively reached forward and put four fingers into her cunt. I could feel that her pussy was full of cum as I started moving my fingers back and forth. As she bucked her pussy against my hand it sank to the wrist. I pushed my hand even further into her pussy as another huge orgasm wripped through her body. I pulled my cum covered hand from her pussy and started jacking off over her pussy. It oly took a few seconds to add my load to the two already there. Afterwords, we dressed in silence and headed off across to park towards home. As soon as we got in the door, I lay on the floor and made her sit on my face. I could tasted the musk of the cum in her pussy, I could feel it rolling down my throat. She had her final orgasm of the night humping my face on the floor using other men's cum as lube.
