I was home on Christmas break when my parents told me that they book a holiday cruise so i would be alone for the rest of the break. that meant i was gonna be alone on Christmas until my big brothers wife Maria called me! she said they would love to have me stay with them for Christmas, i said hell yeah, packed a bag and road tripped to there place. Let me first say that i love my sister in law Maria, she is smart, funny, awesome, and makes my big brother be nice to me! when i got to there place maria showed me to there guest room, i got unpacked and went to chat with Maria. i found her in the kitchen we made some small talk, i thanked her for letting me come for Christmas and then asked where my brother was. she told he was still on a business trip but he was suppose to be flying back this afternoon, since it was Christmas eve and a huge storm was gonna be hitting tonight i was a little worried if we would make it. Maria was worried to with the storm and him making his flight but there was nothing we could to so we started making plans to watch Christmas movies tonight when my brother Mike got home. i went back to my room and played video games for a few hours then i went to ask Maria when Mikes plane was suppose to land. i found Maria in the living room drinking some wine and looking kinda sad, i sat down on the couch with her and asked her what was wrong. she just got off the phone with Mike, the weather got bad and his flight got canceled so he wouldn’t make it home for Christmas! i did my best to comfort her, i could tell she was a little tipsy and that was helping with her sadness. i offered her a hug and she leaned in for the embrace, when i was looking over her shoulder i couldn’t take my eyes off her juicy ass. i dont know what came over me but i slowly moved my hand to ass but the crazy thing that happened is she slowly moved her hand to my crotch and squeezed my dick. i pulled my head back and looked into her eyes and asked if she was sure about this, she told me to go to her room before she changed her mind. before i knew what was happening Maria had stripped to her thong and was between my legs sucking my dick in the bed she shares with my big brother! the nest morning it was Christmas, i rolled over in the bed and saw my still topless sister in law texting on her phone. we said a awkward Merry Christmas to each other and the both got quiet. i decided to break the silence and asked her who she was texting, she said it was my brother. his plane just landed and he should be home in a hour, while she was talking i was playing with my hard dick and she kept staring at it. she finally said fuck it, she already cheated on her husband and she might as will go all the way and have some fun! my sexy sister in law fucked me like a bitch in heat and in the end i filled her up with my nut! Merry Christmas everyone!
