I'm trying not to sound like I'm bragging, but I've over 6'5" and everything is in proportion, and she's barely 5 feet tall and very petite.She sank a...ll the way down - there was a gasp as I hit the end of her, filling every inch. She threw her head back and cupped her right breast in one hand, and while her fingers worked their magic on her clit I cupped her other breast in one hand, squeezing her nipple while my left hand squeezed her buttock.Her rhythm increased - I rose to meet her a couple. It doesn't take more than one to ruin a good party. There were a few minutes that got awkward trying to figure out which room was to be used but Becky solved it by saying, "You are in your women's room. Please, no doubling up tonight if you know what I mean."Breakfast the next morning was a buzz of conversation. Everyone wanted to tell something about their partner. Becky laid down the ground rules, and cautioned everyone not to speak unless it had a happy ending, so to speak. Everybody. She just lifted again and again pounding me repeatedly under her bum, howling with laughter as my gasps got weaker. Eventually tired she settled to just sitting on me, panting from her exertions. Kathleen laughed, "That should have softened him up s*s. turn around and sit on his face and I'll teach you how to wank boys off".Janet turned round and shuffled backwards until her massive backside engulfed my face, I panicked as my airways were cut off by her bulk, but thankfully she moved back a bit. Upstairs as Jane was getting ready to go she talked on her phone with her best friend Jane. Jane had given her the hottest idea she had heard a few weeks earlier, and couldn't wait for her husband to have fun with her when they got back."Now you took the two rolls I gave you right?" Yes Jane, when I get back we're going to fuck all night. He has no clue that I even am doing this, he's going to have so much fun tonight treating me like a slut when we get home." Jane said as she finished putting.
