Sex with the wife has gotten to be so monotonous and she has really let her self go, i have to use my invagination and think about that hot new secretary down at the office just so i can get a nut.

Troy planned his night with his new girlfriend carefully...right down to the candles,wine,soft music and the newly purchased tub of Astroglide for the invagination that he was sure was gonna happen. Unfortunately his girlfriend got too close to the candles and popped before he could even get the wine poured.

Sally and I were about to get busy, but I couldn't since I was dry. She used her mouth to invaginate my penis, and then we got it on.
