Invasion of the vagina with a penis or reasonable facsimile

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.
