I was staying with a couple whom I was friends with, Fred and Jill. We had some wine, and Their friends Tony and James came by and we all chilled out and drunk a few bottles of red wine.
The topic of sex came up (Fred and Jill are swingers) and Jill jokingly suggested a gangbang. Jill suggested that she & I be the ones to satisfy them sexually. They agreed that that would be fun.
As Jill got naked and began to fellate Fred, Tony, James & I got nude. Tony was uncut, muscular with a good body, a 6 1/2 inch penis, while James is just a bit overweight with a big, thick 6 inch penis. I got on all fours and James carefully smeared baby oil on my willing bottom, sliding two slippery fingers into my anal hole. Then as Fred eagerly watched whilst Jill sucked his 7 inch cock, James pushed his glans into my anal orifice, then pushed until his erect penis was embedded balls deep into my hole. It felt lovely as he entered my oiled boy pussy. Once in James fucked me deep in my anal hole cramming his penis all the way in. Meantime Tony grabbed my head and inserted his thing into my mouth. I licked him carefully, then commenced sucking Tony's erect penis, lapping up his pre-cum. Meantime my anus was expanded by James' thick uncut cock. He pushed the cheeks of my buttocks wide open and he described how good it was to see my pink anus gaping wide around his member. James despoiled my arsehole, soon building up to a good hard rhythm, pushing in his cock deep, his balls pressed against my taint, making me squeal around Tony's cock.
