Aunt Bridgette had just finished emptying my balls down her throat and I fell back on the enormous bed. It was extremely comfortable, especially with the over-stuffed pillows and the amount of room one had when lying in it. I lay there as Gram and Aunt Bridgette fell onto the bed next to me. Gram was massaging Aunt Bri's near naked breasts and had her tongue deep in her mouth. Gram was still completely naked and Bridgette was in all black, nippleless bra, crotchless panties, garters and stockings.
Bri had one hand on the back of Gram's head, holding her mouth to hers, savoring the sensation of Gram's tongue. Gram was continuing to massage her tits and tug on her swollen nipples. Aunt Bri released Gram's head and Gram started to kiss and suck on Bri's neck. Bri, tentatively, reached for Gram's breasts and hefted them in her hands.
Bridgette's breathing started getting faster as Gram continued to nibble on her throat and caress her nips. Bri started to massage Gram's boobs and rolled her thumbs over her nipples. Gram had a sudden intake of air and let out a low moan. She continued kissing and nibbling down Bridgette's upper chest. Bridgette had to let go of Grams tits and, instead, began to weave her fingers into Gram's flaming, red hair.
Bri guided Gram to her right tit and she latched on like a babe. She was sucking and tonguing Bri's nipple until it was an inch long. Bri was moaning loudly and her ass was squirming around on the bed. I shuffled down the bed and saw the fluids dripping from her pussy. Gram looked up and over to me.
"Lad, she has another teat. Get on it."
I didn't have to be told twice. I moved back up the bed and took her other nipple in my mouth. I was sucking like milk was going to come out. I was wagging my tongue against it, feeling it getting stiffer. My hand wandered down Bri's belly, tracing my fingernails along. Each pass of my nails made her jump.
I moved over to whisper in my Gram's ear. "Do you want to lick her pussy, like she did you, or do you want me to go down on her again?"
Gram's response was to release Bridgette's tit and start kissing her way down her belly. She maneuvered herself so that she was crawling down between her legs as she traced her tongue past Bri's belly button.
My cock had recovered by this time and was getting harder by the second, watching what was going on between my Gram and Aunt. By now, Gram was laying on her stomach, between Bridgette's spread open thighs. I moved to a position that gave me a great view.
Gram parted Bri's bush, that covered her puss. Licking her lips, Gram moved in closer and planted a kiss on Bri's pussy. She kept kissing her wet lips and I could hear the sound of her sucking as she kissed. Finally, looking over at me, she parted her sister's cunt lips and started running her tongue through the moist pink opening. She was alternating between short little touches of her tongue and long licks, like she was eating an ice cream.
Gram moved her fingers and cleared the hair from around Bridgette's hooded pearl. She moved her mouth a bit and started to lap at that sensitive little button. I heard Aunt Bri repeating over and over, "Yes, God yes." As she started to buck her hips into Gram's now fluttering tongue. I could see a steady flow of fluids out of her cavern as she grabbed Gram by the hair, thrust her pelvis upward and yelled out "Oh God, Yes."
For her part, Gram was down there lapping up as much of her sister's cum as she could get. Bri was still breathing heavily and wheezing as her climax started to come down. I leaned over and kissed my Grandma, tasting my Aunt's cum juice on her lips and tongue. My cock was at full mast, now.
Gran saw it and remarked "Well, what are we going to do about that, lad?"
I moved over to Bridgette and started turning her on her stomach. "Well, somebody here mentioned something about a snake in her cunny, earlier."
I got Bri on her belly and was pulling her hips up. "I think it's time I do something about that."
I finally had her on her knees with her beautiful ass in the air. She tried to get up on her hands as well, but I kept her in the position she was in. I hunched down behind her and inserted a finger into her sopping wet cunt. I started finger-fucking her, slowly, at first and increasing the speed as she got used to it. I added finger after finger into her poon until I had 4 fingers pumping into her.
She looked back at me and said, "Thas nice boy, but I was promised that log in ye groin." "And ye, sis, come around here so I can return ye the favor."
