Over the Xmas break , i've got myself into a real tangle . My new gf's daughter came back from uni and we ended up shagging . We're both in our 40's and my gf 's daughter is a lovely 20 year blonde with a real slim body and long legs. A spitting image of her mum. I work in the construction sector and with an extended holiday , it meant I was spending more time at the flat whilst my gf working for in retail was out from dawn till late. Her daughter was also lazing around the flat , often sleeping till late and then walking around in pyjamas. We gone really well and when my gf used to arrive , i was well horny ready for some core sex. With her tired , it used to be quick , with me doing all the work and she laying down or bent over . To build up the excitement , thoughts of her daughter used to come in my head when fucking my gf. This would lead me fucking harder and building my cuming even more pleasurable. My gf is quite loud when she cums and with my hard fucking she used to cum with a loud scream . One of the morning , after my gf left , i woke with a hard on and started to wank myself thinking of her daughter. I imagined licking her wet pussy , sucking her nipples and bending her over the sofa for rough sex. The speed of my wanking increased and i ended up shooting my spunk all over the duvet . As I walked naked towards the bathroom for some tissues, he daughter came out of her bedroom with a tiny nightie on . I froze looking at her , with a semi . She looked at me and commented 'i see my mum doesn't satisfy you enjoy' .. I instanly became hard , and she noticed my 7 inch rising . 'Oh that's wot makes my mum scream at night' she joked. She walked toward me and planted her hand on my cock and softly started to wank it . 'Wow , that's hard and hot ' she commented . I lent forward and we snogged . Her tongue was deep inside me . Both of hands around her waist and I slipped her nightie off . She led me to her bedroom. She was totally naked , her nipples poking up and with her shaven pussy in front of me with her legs in a V shape. 'Lick me, like you do with my mum' she demanded . I positioned my head in between her legs and stared to tongue caress her thighs and eventually to her soaking pussy . 'Deeper' she whispered while moaning . My tongue was deep inside her licking out her juices . I pushed my index finger in her too . She began to softly scream as my finger speed increased . Her lovely pussy was soaked with her juices and my saliva. I wanted to fuck her , I moved up towards her mouth and made her taste her juices by deeply snogging her. Playing safe , I entered her from the top . She guided me in and then wrapped her legs around my waist . I began to fuck her deep and hard . Levering myself on my hands , continued to fuck her rough, she loved the deep strides . She raised her legs over my shoulder for deeper entry . I began to lick her nipples at the same time. I felt the precum and increased the speed again , until my 2nd load of the morning shot deep in her. I continued until she screamed the house down with her orgasm . We snogged afterwards and layed together on the bed together in silence. She broke the silence by saying 'i'm here for another 3 weeks , let's continue to have fun ' I showered got ready and made breakfast while she dressed up in her bedroom. After breakfast we sat on the sofa cuddled up and snogged many times. During the last 2 weeks , i have been fucking her most days and then fucking her mum in the night ...
