My wife and I are now in a very good swing with our neighbour Nicky (a single BBW) and her boyfriend. My wife is quite a large woman as well, but Nicky is really big, with huge tits, belly and thighs. We’re now at the stage where the four of us meet about once a week and have a great fuck session. Nicky’s boyfriend has been good about it which is a relief since this isn’t what he was expecting when they hooked up. It only became clear recently that Nicky likes things rougher than my wife, and both my wife and I are taking advantage of this now. But the main thing we do is try to intensify each others’ orgasms. I started the ball rolling by biting Nicky (gently!) on her back while I was fucking her from behind. My wife never liked this much as she prefers to concentrate on the sensations down below, but Nicky has really huge orgasms if I bite her and pull on her nipples during a good hard fuck. She prefers it from behind a fair bit of the time due to her sore hip bones, loving hard thrusting from either my cock or from my wife’s fingers or vibrator. Sometimes the missus will play with Nicky’s tits while she cums, and she makes sure she seriously sucks them. Nicky cums harder and harder with all this physical stuff and it’s great to watch. My wife and I were in the lounge room at Nickys watching her and Michael fucking on the settee. They’d only been going 2 or 3 minutes. Nicky was face down with her big beautiful backside in the air and they were getting closer to the finish with every thrust. We were cheering Michael on, calling harder, harder to him and he really started to give Nicky the business, slapping against her thighs and into her pussy with great force and she responded by grunting and whimpering with pleasure and we knew she’d cum soon. She had her hand down underneath and was frantically rubbing her clit at the same time. The missus scuttled over to the settee and pulled Nicky’s left tit out to the side and sucked hard on the nipple. Nicky’s eyes flew open and she said ohh fuck oh fuck harder, like a bad porn film, but she really meant it and was flying. There were a few more slaps as Michael grunted his way into her faster and faster and then she came loud and long, yelling fuck fuck fuck as my wife hung off her tit for all she was worth. Nicky went rigid and as she did so we saw Michael lose control and shouted out his own orgasm as he came deep inside. It was a great spectacle. Michael got up and sat on another chair. The missus sat with Nicky on the settee. Nicky said, I don’t think I can do another of those for a while. I said why don’t you just enjoy this. I waddled over on my knees, naked, and positioned myself in front of the missus. I reached under her thighs and helped her slump down on the settee and bring her groin to my face. I dived in, licking and nipping gently at her pussy lips and clit. She was already wet-- she gets aroused watching, as it turns out-- so I just knelt there and licked merrily away to my heart’s content. Nicky leaned over and stroked my wife’s tits gently and we all enjoyed that for a while. Michael came across the room, limp, and started kissing the wife, so now she had the three of us working on her and she was starting to get into it in a big way. I sucked her clit gently and she started rubbing herself on my tongue and breathing up. I slipped my fingers into her pussy and spread the wetness all around. The wife said lets do what Nicky and Michael were doing, and without a word we all got up and my wife positioned herself on all fours, arse right up in the air and I got in behind her and slipped in. She was really wet and beautifully hot. Michael went back to his seat. Nicky did what the missus had done before-- pulled a boob out to the side and gave it some treatment. The wife didn’t say a word, but she liked it a lot. Her pussy was twitching on my longer strokes, so I knew she was going to cum big. The missus supported herself on her elbows, so Nicky used her hand on the wife’s clit, stroking me as I came out each time. With her other hand Nicky massaged my wife’s backside, something she loves to feel while I’m fucking her. The wife got more and more wound up with all the pushing and stroking, and soon she was moaning ahh ahh and her cunt was really opening up as I gave her long deep strokes. Nicky switched from massaging the wife’s bum to mine as I thrusted in and out, without losing her rhythm on the wife’s clit. With a set of longer louder moans the wife started cumming and her pussy clamped down on my cock, making me cum straight away. She was going ahh ahh ahh Jesus Nicky ahh and it took easily 30 seconds for her to come down from this massive orgasm. I was in there, but I was limp. There was stuff everywhere, all down our thighs and on the settee...
