"What took you so long" Susan asked. "I had to go to the toilet" said Allie. I looked at Allie and smiled at her and she returned my knowing smile. Liam was in the pool splashing around so I dropped my stuff ran and dove into the pool surfacing next to him. Allie followed close behind as Susan continued to read her book and get a suntan. A few hours later we ventured over to the cafe for lunch, grabbing hamburgers, fries and cokes for all four of us. We sat and ate lunch talking and laughing all through the meal just like any other normal family. At the end of the meal Susan suggested that Liam have a rest back in the room and Allie and I can stay by the pool. We were both happy with that idea as we could rub and touch each other in the pool under the guise of normal father daughter playing. So we again head in opposite directions. Susan took Liam up to the room and suggested he wash his hair in the shower. So Liam pulled his trunks off revealing his untanned white butt and his small boy cock devoid of any hair. "I'll be in a second to wash your hair for you" Susan shouted as she undid her bikini top and let her firm breasts fall free. Liam looked through the door at his mom getting undressed and his little cock immediately began to harden. Susan slowly slid her bikini bottoms down revealing her clean shaven mound and plump pussy lips. "I can't hear the water Liam, what are you doing" asked Susan. "Nothing mum, I doing it now" he replied Liam turned and jumped in the tub and turned on the water for the shower. After waiting for it to warm he eased himself under allowing the water run over his head. A minute later he heard the door open and his mom enter the bath room and the shower curtain pulled back and then closed. Liam wiped his eye and blinked a few times to find his mom is in the shower with him totally naked. "W w what are you doing mom?" he stuttered. "I need a shower too so let's share. We used to do it all the time" she said nonchalantly reaching for the soap. "But I'm too old to share a shower with my mom now" he argued knowing too well the sight of his naked mom was going to cause his cock to harden. "You're never too old to share shower with your mom silly boy. Anyway I've seen everything you have " she laughed looking down at his boy cock. He turned back knowing he was defeated and waited for the inevitable. Sure enough 30 seconds later his cock was rock hard. His mom started to wash his back and ass cheeks before she turned him around to do the front. Liam just closed his eyes and turned bright red. "Oh my" Susan exclaimed. Susan looked up at Liam but his eyes were closed. She felt embarrassed for him. She soaped her hand and gently washed his hard cock. She could not believe how big it was. She continued to wash it and then wrapped her hand around the shaft and started to wash up and down the shaft, at least that what she told herself. She was in effect masturbating her own son. Liam's breathing became more intense as Susan pumped his shaft up and down. Liam's own body now betrayed him as his hips started to move to the touch of his mother's hand. Susan now got down on her knees as she continued to pump her sons cock and without thinking opened her mouth and took the head of his cock into her mouth. She was beyond caring about the soap and sucked his cock between her lips as her tongue swirled around the shaft. "Mmmmm" was all Liam could say. Liam's hips were now moving faster and faster as his cock pistoned in and out of his mom's mouth. "Oh god I'm gonna pee mum" Susan pulled his cock out of her mouth and said "Cum on mommy baby. Shoot your cum in mommy's face" Susan continued to pump and then suddenly a stream of cum splashed into her left cheek. She opened her mouth and caught the next in her mouth. She pumped and pumped as her sons seed slid down her throat into her stomach and down her chest and across her hard nipples. "Mom what did you do" asked Liam after he had recovered from his orgasm. "I'm sorry baby, please forgive me." Susan cried. "It's just been so long since your dad and I made love the sight of your hard cock drove me crazy." "Don't cry mom I loved it and I love you, so it's OK" he comforted Susan. "I'm sorry baby" Susan continued to cry as she reached up and kissed Liam on the lips. "Please mom I wanted to do it. I want to do more with you" Liam pleaded with his mother. Susan just kept kissing him on the lips, little pecks between her sobs. Then her kisses started to linger a little longer and harder as Liam started to kiss his mom back. Susan responding to her son's enthusiasm opening her lips and Liam followed suit as their tongues met midway between them. Their kisses were now full of passion as they hugged naked flesh on naked flesh, as their fondled each other in the shower. Susan suddenly pulled away from Liam much to his disappointment but then she uttered the words he would remember for the rest of his life. In a low soft voice almost too scared to utter the words "Fuck mommy Liam. I want you to stick your hard cock in my cunt and fuck me. Will you do that for mommy?" "Oh god yes mom, where do we do it?" he asked enthusiastically. "On the bed" she replied They hurried out of the shower drying themselves before running to the bed side by side holding hand and giggling like teenagers. Susan quickly lay on her back and motioned for Liam to join her. Liam crawled up onto the bed and between his mother's legs. Susan guided him in and grabbed for her son's hard cock. She was impatient to feel a cock, her son's cock deep inside her wet cunt. It had been a long time since she was satisfied and she was not willing to wait any longer. She aimed Liam's cock at her pussy which was slick with anticipation. Liam's small hard cock entered his mom's pussy for the first time. Susan was on sexual fire pulling her son into to her hard and wrapped her legs around him and pulling him into her even more. "Fuck mommy baby. Fuck mommy's cunt" she begged her son. "OK mommy, oh god this feels so good" he replied. Susan guided Liam's action, not before long he got the idea and was pumping into and out of his mom's pussy as hard as he could. "OH OH OH FUUUUCCCKKK" cried Susan as her long awaited orgasm hit her slender frame. "FUCK ME HARD BABY" She screamed "Suck mommy's tits" Liam did as he was asked and sucked on her red hard nipples as he had done not that many years ago as a baby. He licked around her nipples and then took the left nipple into his mouth and sucked on it like a baby, running his tongue over the hardened nipple. That was enough for her as an orgasm rocked her entire being and she shook with utter lust. Liam just kept fucking her as hard as he could as his mom's orgasm peaked and another on built. "Fuck Liam keep fucking me, this is the best fuck I have ever had" she mewled in his ear. "Even better than daddy?" he asked "Fuck yeah baby, you are a stud. You know how to get mommy off baby. Keep f f fucking me" she stuttered as another orgasm built up deep within her body. "I I I'm gunna cum mum" Liam panted "Shoot it in me baby. Give mommy all your juices" she said kissing him on the lips slipping her tongue into his mouth. Liam shut his eyes and let go sending shot after shot of cum into his mom's fertile womb. Which in turn sent Susan to another orgasm. "OH OH OH OH GOOOOODDDD FUUUUUCCCCKKKKKMEEEE" she screamed as she came hard again. Liam collapsed into his mother's arms his cock still deep inside her cunt. They both were heaving hard for breath as they tried to recover as Susan planned their next fuck as soon as her son recovered. Suddenly there was a clapping from the doorway.
