Letters to Penthouse XXXVI by Penthouse International

Ass
    One of the perks of dating a much older man is that he’s as experienced as I could hope for. There’s no shy fumbling or uncertainty
     when we hop into bed—or when we take turns tying up or spanking each other. My boyfriend, Alan, has definitely been around
     the block and knows what he likes, plus there’s something so sexy about being twenty years his junior. I like the attention
     we get when we hold hands on the street and the fact that even though he’s older, his body’s strong and solid. He works out
     every day and certainly has no trouble getting and keeping huge erections.
    For his fiftieth birthday, I planned a surprise party and told everyone to be prepared to give my man some birthday spankings.
     Thinking about him blindfolded and bent over, awaiting a smack from an unknown hand, was enough to make me jerk off while
     I took a shower. When I emerged, I was still horny and pounced on him. He was lying in bed reading a book, completely naked
     with his upturned ass right in my line of vision. I straddled him, massaging his shoulders before working my way down. “Hey,
     baby,” he said, turning his head enough so I could give him a quick kiss. But when he tried to turn all the way around, I
     pushed him back.
    “Stay there,” I said as I rubbed his back until I reached his butt, which I kneaded in my hands before raising one to give
     him a firm, sharp whack.
    “Oh, Kristen, you know how to get me in the mood,” he said as I continued to spank him, sure that I’d find a healthy erection
     when I finally stopped. He moaned and kept arching his ass closer to my hand. I felt the sweet sting in my palm as I spanked
     him, knowing that he was enjoying this impromptu smacking session as much as I was. I finally took a break, fingered my pussy,
     then let my wet digits trail over his balls.
    “Are you ready to fuck me?” I asked. He turned over, climbing on top of me. The spanking had gotten me so horny, I needed
     his cock inside me as soon as possible. He slid his dick into my waiting hole and pumped me good and hard, the adrenaline
     rush from his spanking spurring us on to powerful, simultaneous orgasms.
    His reaction told me that my plan for his birthday was right on track. I’d made sure that he was occupied by friends during
     the day, so I could get our place ready for the party. I told everyone to hide as we waited for Alan to arrive with his best
     friend, Dave. When we heard their voices, we quieted, and I felt the excitement in my pussy as their conversation carried
     through to the silent living room. His key turned in the lock, and no sooner had he stepped through the door than we all yelled
     out “Surprise!”
    Alan struggled to contain his laughter. Then a huge grin broke out across his face. “You guys! I had no idea!” He punched
     Dave lightly on the arm before seeking me out. The look on his face told me how shocked—but pleased—he was. And he didn’t
     even know what else was planned yet! I walked toward him and gave him a lusty kiss to the cheers of our friends. I had my
     arms around his waist and hugged him tightly before dropping my hands down to his ass. I gave it a light squeeze, then pulled
     away from the kiss to say, “Happy birthday.” He looked around again and then started to mingle. I didn’t let on right away
     what we had in store for him, but I allowed him to chat with our friends while I lined up my ten designated spankers.
    I figured if Alan would like other people to go past fifty, he could request it later, but these ten I’d chosen were friends
     who were eager to get their hands on my man’s ass and would do a decent job. I had them stand in one spot, then lured Alan
     away from his birthday cake, wiping remnants of chocolate frosting from his cheek. “There’s another surprise, one I think
     you’re really going to like. It’s time for… birthday spankings!” He gave me a look for a moment, as if trying to figure out
     if I was really
