This happened when I was 35 and She was 20. I'm 6 ft, 190lbs and she is 5'4' I say about 165.
I took a week off to get some stuff done around the house. So everyday I would sit outside have my coffee and talk to the mail man for a bit as he has been our mailman for six years or so. So Friday rolls around and I see a young mail lady, hair up in a pony in uniform but ample on top if you know what I mean. The day is really hot and humid, I can see she is sweating buckets. As she comes by she smiles gives me my mail. I offer her a glass of cold water and she says yes please. I tell her come in and enjoy the AC.
I get her a tall glass of water and sure enough the cat runs by and trips me. I splash the water all over her landing on the floor!
I get up saying sorry over and over. When I stand up, she is soaked and I can see the outline of her big tits. I ask her if she wants to put her top in the dryer. She says sure and takes it off in front of me. I get an instant hard on looking at her in her white bra and big tits. I take her top go downstairs, she follows me. I put the top in the dryer. I nervously try not to look at her.
She suddenly laughed and says liking my tits are you and points at my hard on. I say god yeah, they look great. Show me how much she says next and I will show you them. I drop my pants and release my 7' rock hard cock. She says stroke it for me, come on. I start stroking slowly and next she reaches back and undoes her bra. The tits were huge with big torpedo nipples. Next thing I know she grabs my throbbing cock and pumps it really fast. I groan as cum starts spewing from my cock.
Beep dryer done, hand her her top she gets dressed and leaves. A+ mail service
